SUMMARY OF CHANGES

SECTION A - SOLICITATION/CONTRACT FORM

The required response date/time has changed from 20-Oct-2015 04:00 PM to 10-Nov-2015 04:00 PM.

The following have been modified:

OVERVIEW

The Personnel Recovery Device (PRD) is a militarized personal locator beacon, and part of the Personnel Recovery Support System (PRSS), designed as an alert and notification system that a Soldier has become isolated, missing, detained or captured (IMDC). The PRD will be capable of transmitting both non-secure and secure waveforms.

The non-secure distress signal will be transmitted over the Cospas-Search And Rescue Satellite Aided Tracking (SARSAT) network; the secure encrypted signal will be transmitted over a Government owned and monitored network.

The PRD contractor is responsible for the non-secure waveform and an interface range to allow for Government programming of the secure waveform; the Government will provide the PRD contractor with a surrogate waveform as Government Furnished Information (GFI) in lieu of the secure waveform. The actual secure waveform is classified, and will never be provided to the contractor. The PRD contractor shall use the surrogate waveform for its PRD design, qualification and acceptance testing. The secure waveform will be inserted into the PRD by a Government agency upon receipt and acceptance of the PRD by the Government.

Two (2) Phases are envisioned for this procurement to reach the desired objective PRD production rate capability and qualification of a single contractor to produce a maximum approximate quantity of eighteen thousand (18,000) PRDs annually.

Vendor Questions:

All questions in regards to the subject RFP shall be submitted in writing via email to ACC-APG, ATTN: Michael A.

Mitchell at michael.a.mitchell3.civ@mail.mil. The cut-off date and time for questions is hereby established as 3:00 p.m. EST on 16 October 2015. Questions submitted after the cut-off date and time may or may not be answered.

The Government will determine if answering questions submitted after the cut-off date and time is in the best interest of the Government.

1 SCOPE

This specification defines the functional, mechanical, environmental quality, test and verification requirements for a new Personnel Recovery Device (PRD). The PRD is an alert and notification transmitter carried by US soldiers at risk of becoming isolated, missing, detained or captured (IMDC). The PRD transmitter is an element of the next-generation Personnel Recovery Soldier System (PRSS).

1.1 Item Description

The PRSS Increment 1b system consists of the new mil-spec personnel locator transmitter PRD, a secure waveform mode, and an operation transport layer consisting of various receivers integrated into a DOD Search and Rescue/Personnel Recovery (PR) network architecture as shown in Figure 1.

Figure 1. PRSS increment 1b functional block diagram

The PRSS Increment 1b PRD is a variant of a commercial off-the-shelf (COTS) Personnel Locator Beacon (PLB) but includes both a legacy COSPAS-SARSAT mode (non-secure mode) and a new secure communication mode with additional capabilities. The PRD offers improved accuracy, decreased latency, smaller size, and has lower power consumption as compared to commercially available COSPAS-SARSAT PLBs. When operating in the non-secure mode, the PRSS Increment 1b PRD is intended to operate in precisely the same manner as commercially available COSPAS-SARSAT PLBs and is intended to meet the applicable sections of the Specification for COSPAS-SARSAT Distress Beacons C/S T.001 Issue 3 – Revision 14 October 2013. Requirements for the PRD include the non-secure COSPAS-SARSAT mode as well as the new secure mode.

3 REQUIREMENTS

3.1 PRD Functional Requirements Overview – Secure Mode Description The PRD is intended to be a rugged, hand-held, radio transmitter with miniaturized electronics, having a built-in Global Positioning System (GPS) receiver module, used for signaling soldier distress. The PRD operates within the 406.0 to 406.1 MHz band in the non-secure mode. In the secure mode, the PRD operates on a government-selected frequency within the range of 360 MHz to 425 MHz. PRD units issued to soldiers by the Government are set to operate in either the non-secure or secure modes but not both modes simultaneously. The soldier is neither permitted nor able to switch from one mode to the other. This operation can only be accomplished by trained Government personnel (e.g. Signals Officer, COMSEC Custodian). In the secure mode, the PRD transmits a digital distress message containing PRD identification information and a GPS position to remote receivers. The messages (including GPS location) are encrypted to protect PR data from adversarial or casual interception. Factory-produced units are to be delivered to a Government facility where final configuration parameters are loaded into the PRDs and tested. These configuration parameters are input into the PRD via a cabled connection or other physical connection to the PRD – a wireless connection is not permitted. This step is completed and the unit is retested using a Government Furnished Equipment (GFE) test set. The product manufacturer will be supplied a similar GFE test set which tests waveform and communication link functions for use in final acceptance testing at the factory. Although the configuration parameters may be changed at the factory multiple times, neither the issuing site nor the soldier will have the ability to make configuration changes. The issuing site will only have the ability to change the mode between secure and non-secure as well as update device time.

3.2 PRD Level of Repair/Maintenance

The PRD shall be designed and manufactured in a manner that supports the level of repair/maintenance as shown in Table 1 below.

3.3 Non-Secure COSPAS-SARSAT Function

The PRD shall perform as a COSPAS-SARSAT PLB with respect to waveform and function per C/S T.001 with the following exceptions. These exceptions are detailed in their respective sections of this performance specification.

• User replaceable batteries

• Configuration parameters allowing for device “personality” changes (e.g. Transmit Repetition Interval Multiplier (TRIM))

• Operating Temperature Range (Class 2)

The PRD is required to pass full COSPAS-SARSAT compliance against C/S T.007 approval standards except for deviations required in this performance specification. Compliance testing will take place during Qualification Testing (QT).

3.4 Electrical Requirements

The following requirements pertain to the secure mode unless otherwise specified. All measurements shall be verified using methods defined in C/S T.007 unless otherwise specified.

3.4.1 Antenna(s)

The device shall use a single Ultra High Frequency (UHF) antenna common to both secure and non-secure modes. The antenna shall be compliant per C/S T.001 with the following exceptions.

The antenna shall operate over the frequency range specified in paragraph 3.4.5 and shall be linearly polarized. Antenna Voltage Standing Wave Ratio (VSWR) shall not be measured with integrated antennas as long as Equivalent Isotropic Radiated Power (EIRP) meets specification in section 3.4.2.

The device shall be equipped with an integral GPS antenna.

Operation of the antennas in any normally operational position, combination, or sequence shall not result in a failure of the PRD to successfully fulfill all performance specifications. The PRD shall not be damaged when operating with either a short or an open circuit on any antenna circuit.

3.4.2 Transmit Power

EIRP shall be compliant per C/S T.001 with the following exceptions. EIRP across the secure mode frequency band (defined in 3.4.5) shall be 5W nominal +2dB/-7dB. Output power rise time of the non-secure and secure signal shall be less than five (5) milliseconds measured between the 10 percent and 90 percent power points.

EIRP shall be measured as defined for a PLB in C/S T.007 using configuration B.2 of C/S T.007.

3.4.3 Secure Mode Spurious Emissions

Spurious and harmonic emissions shall not exceed the levels specified by the following signal mask, when measured in a 100Hz resolution bandwidth.

fc fc + 1 tm fc + 2 tm fc + 4 tm fc + 5%

0 dBc

-15 dBc-15 dBc

Figure 2: Secure mode spurious emissions mask

3.4.4 Transmit Repetition Interval (TRI)

The PRD shall have a configurable Transmit Repetition Interval (TRI) which specifies the time between the leading edges of consecutive device transmissions.

The PRD shall have five configurable TRIs, TRI(1) through TRI(5), with an associated five durations D(1) through D(5) which shall be available for each mode, secure and non-secure. As with all other configuration parameters, the TRIs and durations D shall be stored in non-volatile memory within the PRD such that the removal of batteries does not affect parameter storage.

As an energy saving mechanism, the PRD shall be capable of using a given TRI(1) repetitively for D(1) seconds, then transition to the next TRI(2) repetitively for D(2) seconds followed by a TRI(3) for D(3) and so on until the batteries are exhausted.

In the event the PRD reaches the end of the final duration (D5), it shall continue the programmed TRI(5) until the end of battery life or the device is deactivated.

The secure mode shall have a fixed 30 second delay and the non-secure mode shall have a fixed 50 second delay prior to the first transmission following PRD activation. In the event of a device reset while in an active mode (Ex. End of battery life), the PRD shall use the same 30 second and 50 second secure and non-secure mode delays prior to resuming transmissions.

Non-Secure Mode: The PRD shall have a TRI as described per paragraph 2.2.1 of C/S T.001 with the following change:

The PRD shall constrain non-secure mode TRIs to integer multiples of the repetition interval described in paragraph 2.2.1 of C/S T.001. TRIs for the non-secure mode shall be implemented via a configurable Transmit Repetition Interval Multiplier (TRIM) that adjusts the TRI on multiples of approximately 50 seconds. The TRIM parameter shall be an integer number having a valid range from 1 to 255. In non-secure mode, the TRI is not directly configurable; instead it is automatically calculated from the configurable TRIM parameter. The TRIM parameter is only used in the non-secure mode.

• TRI(1-5)_Non_Secure = (~50 seconds * TRIM)

• TRIM_Non_Secure = 1-255

• D(1-5)_Non_Secure = 0-65535 seconds

Figure 3: Non-Secure Mode Transmit Parameters

Secure: The PRD shall have five configurable secure mode TRIs with five accompanying durations. Unlike the non-secure mode, the secure-mode TRI is a configurable value directly.

• TRI(1-5)_ Secure = 36-4095 seconds

• D(1-5)_Secure = 0-65535 seconds

Duration #1 (D1) Duration #2 (D2) Duration #3 (D3) Duration (D)

**TRI is not a user parameter in non-secure mode. Instead, it is automatically calculated using the Transmit Repetition Interval Multiplier (TRIM) user parameter. TRI = TRIM * 50 Sec. For example when TRIM = 2, TRI = 2 * 50 = 100 Seconds.

3.4.5 Transmit Frequency

In secure mode the PRD shall have configurable frequency from 360MHz to 425MHz and be capable of 1 kHz steps.

3.4.6 Transmit Modulation

The secure mode transmit modulation shall be Binary Phase Shift Keying (BPSK) with an Error Vector Magnitude (EVM) no greater than 10%.

In order to meet the secure mode spectral mask defined in section 3.4.3, the PRD will likely need to have digitally filtered baseband data. Additional information regarding waveform shaping shall be included in the Secure Mode Waveform Specification.

The secure mode transmit modulation bit time shall be configurable from 1.60uS to 40.00uS and be capable of 100nS steps. The bit time shall have no greater than 5 parts in 106 of timing error.

3.4.7 Transmission Length

The PRD shall transmit the secure waveform for up to 2.1 seconds depending on configuration parameters loaded.

3.4.8 Transmit Frequency Stability

The PRD shall meet transmitted frequency stability as defined in C/S T.001 with the additional secure mode short term variation to not exceed 10 parts in 109 in 1 second across the operating temperature range.

The configured transmit center frequency shall not vary more than 5 parts in 106 from that configured center frequency in 5 years.

3.4.9 Global Positioning System (GPS) Functions

The transceiver shall include an integrated commercial L1 GPS receiver capable of acquiring (in conjunction with appropriate antennas, 3.4.1) and processing GPS satellite signals to generate GPS location data with an accuracy of 20 meters threshold, 10 meters objective.

*Fixed 30 Sec. delay after user activation never Changes

The PRD shall include an initial GPS position no later than the second non-secure mode or secure mode transmission from a cold start and clear view of the sky. To allow for adequate GPS position refinement, the Time-to-First Fix (TTFF) shall be no longer than 65 seconds after activation. If for any reason GPS acquisition is not immediately possible, whenever the initial GPS coordinates are obtained, the PRD shall transmit the position at the next in-cycle non-secure mode or secure mode message. While attempting to acquire or update position data, the GPS function shall be full time. During secure mode operation, the GPS position shall be updated prior to each transmission. If a position fix is unavailable within 65 seconds of the time of transmission, the position data in the emergency message shall be filled in with a default value (defined in the Secure Mode Waveform Specification). During non-secure mode operation the GPS updates shall conform to C/S T.001.

3.4.10 Real Time Keeping

The PRD shall have a Real Time Clock (RTC) that maintains a maximum clock drift of 54 minutes for five years (20 parts in 106) before a clock resetting is needed.

3.4.10.1 Clock Operation Holdover

The PRD shall maintain a holdover time of 10 minutes to allow for battery replacement in the field without the RTC resetting.

In the event the RTC is reset while in Secure Mode, the PRD secure waveform shall use a default time value until the RTC is set by an authorized, trained user. While in Secure Mode the PRD shall sense if the RTC has reset and shall provide an indication within the Built-In Self-Test (BIST) defined in section 3.4.15.

3.4.10.2 RTC Time Sync Procedure

The PRD shall have an RTC time sync procedure that pertains only to the Secure Mode of operation. A loss of RTC time while the device is in Non-Secure Mode shall not impact device behavior.

The PRD shall allow RTC time synchronization (as indicated by a BIST failure while in Secure Mode only) if the batteries have been depleted, removed for longer than the clock operation holdover, or 5 years has elapsed since it was last set.

The procedure shall be complex enough that a soldier in the field cannot accidentally put the PRD into RTC time sync mode. The RTC time sync mode shall only be available if a BIST failure has occurred.

The RTC time sync procedure shall be performed only at a Government installation where trusted GPS time and position have been verified directly prior to the RTC time sync process.

Once the RTC time sync mode has been entered, the PRD shall attempt to acquire GPS and then automatically set the RTC to trusted GPS time. The PRD shall give visual feedback of RTC time sync success or failure.

The RTC time sync procedure shall also be possible through the Universal Serial Bus (USB) configuration interface as well as through an OEM defined procedure without utilizing custom equipment. Field RTC time sync shall not require a computer interface to set trusted GPS time.

3.4.11 Battery(s)

The PRD shall be powered by non-rechargeable lithium battery(s) of type CR123A or commercial equivalent. The battery(s) shall be replaceable by an untrained person without the use of special tools. Replacement shall be accomplished without damaging PRD environmental integrity.

The PRD shall operate > 24 hours (threshold), > 48 hours (objective) across the operational temperature range once activated. Operational duration shall be tested in accordance with C/S T.007 Paragraph A.2.3 with the changes listed in this section. The PRD shall be designed and manufactured in a manner that supports the level of operational duration as shown in Table 2.

Activated Operational Duration Transmit Repetition

< = 6 minutes 24Hrs Secure -10F (-23C) 150F (65.5C) 24Hrs 48Hrs

Table 2: Activated Operational Duration

The following configuration shall be used to demonstrate the operational duration at a temperature of -10F (-23C). The following assumptions are made for the transmit repetition interval:

• Non-Secure: S1-S5: D=65535, TRIM=2 (continuous 110 second TRI)

• Secure: S1-S5: D=65535, TRI=360s (continuous 6 minute TRI)

The standby duration of the PRD shall be > 1 year (threshold), > 5 years (objective) across the operational temperature range while leaving enough battery capacity to perform the required activated duration. In the standby mode, the device shall maintain its real time clock (RTC).

The PRD shall be designed and manufactured in a manner that supports the level of standby duration as shown in Table 3.

3.4.13 Reverse Battery Protection

The PRD design shall have reverse battery protection to prevent electrical damage of the PRD and batteries if the batteries are installed incorrectly.

3.4.14 PRD Indicator Lights

Light Emitting Diodes (LEDs) shall be visible on the exterior of the PRD case. The LEDs shall illuminate in coded patterns to indicate the status of PRD transmissions, GPS functions, and self-test results. LEDs shall indicate normal PRD operation, GPS status, successful transmission, abnormal operation, and failure condition(s).

3.4.15 Built-In Self-Test (BIST)

The PRD shall have a BIST diagnostic capability to verify operational readiness. The software shall not contain proprietary restrictions. The level of BIST diagnostic capability shall be in accordance with (IAW) the PRD Specification and strive to achieve 99% accuracy. The PRD BIST shall perform the following functions:

• Indicate that BIST is in progress

• Detect if the real time clock has reset and present a failure via a visual means in the event of an RTC reset (Secure Mode only)

• Estimate remaining battery life by:

o Verifying battery voltage is not end of life o Count all non-time based energy consuming processes (e.g. BIST, Transmissions, GPS updates, etc.)

• Recognize when batteries have been changed and reset an internal counter to ensure

BIST accuracy for battery voltage end of life indication

• Indicate if the PRD is in secure or non-secure mode

• GPS functionality

The BIST check indicators shall display pass/fail information. If a failure occurs during the BIST check, the LEDs shall indicate the type of failure. The PRD shall interface with a computer for detailed BIST result reporting. The PRD shall have a diagnostic mode that displays detailed BIST results via the USB computer interface. The BIST function shall be initiated by a button on the PRD case and through USB computer interface.

3.4.16 PRD Activation/Deactivation

The PRD case shall incorporate functional controls on its exterior to enable operator manual activation. On the exterior of the case, the PRD shall have manual button(s) that precludes inadvertent operation, such as a cover or detents. This inadvertent operation safeguard shall prevent possible erroneous button presses. Inadvertent PRD activation shall be shutdown manually by the operator. Button activation shall be discernable tactilely (by touch) and shall be operable with one hand and without the use of any tools.

The PRD shall only activate when the distress button is continuously depressed for 5 seconds.

Inadvertent PRD activation shall be shutdown manually via functional controls on its exterior.

3.4.17 Multi-PRD Interoperability

At a minimum, four (4) PRDs shall be able to function concurrently within a 100 ft.2 area at a minimum distance of 1 ft. apart, to ensure proper signaling and GPS operation. The PRD shall not be disabled by inadvertent noise or jamming, and shall not be disabled if there is deliberate jamming.

3.4.18 PRD Activation User Feedback

Any form of PRD user feedback shall be covert for secure mode activation (e.g. visual indicators have reduced brightness while activated) so as not to alert adversaries in the immediate area.

PRD user feedback does not need to be minimized in the non-secure mode.

3.4.19 Programming Anti-Tamper

The PRD shall be designed to prevent software configuration from being changed by an unauthorized person. Authorized persons shall be required to present the secure mode Unit Identification to the device before the PRD will allow new parameters to be changed.

3.4.20 Non-Secure to Secure Switchover

The switchover method shall be performed by appropriately trained and authorized personnel only. The switchover shall not require specialized tools to switch the PRD from non-secure to secure modes of operation. A non-wireless physical mode switching capability is preferred, however; neither the environmental integrity nor the operational reliability of the PRD shall be compromised. The intention of this requirement is to keep soldiers from changing the device mode once the PRD has been issued. The time associated to switchover the PRD shall be within two minutes.

The selected mode shall be evident by visual indicators on the PRD.

3.4.21 Transmit Data Characteristics

Basic secure mode data transmission characteristics shall include the following. Additional characteristics shall be supplied in the Secure Mode Waveform Specification.

• Differential encoding

• Digital channel encoding and access schemes

• AES256 data encryption

• The user interface shall be password protected using the device’s secure mode 6 digit hex Unit ID (UID) as the password. Until the UID is changed, the default shall be “000000”. If an incorrect password is entered 5 times in a row, the PRD shall lockout the configuration interface for 10 minutes. If the interface cable has been removed the interface shall return to password protected status. If the PRD cannot sense the cable connection, then it shall timeout and return to password protected status after 10 minutes of inactivity.

• Upon USB connection the device reads out the following basic parameters without password entry:

a. RTC Time
