4.0 SINCGARS INTERFACE AND CRYPTOGRAPHIC KEY LOADING INTERFACE (J1)

4.1 Physical Interface.

4.1.1 SINCGARS. The SINCGARS interface transfers SINCGARS Time Fill data from the AN/PSN-11 into the SINCGARS radio via J1. Refer to Figure 4-1 for J1 contact locations.

Figure 4-1. AN/PSN-11 J1 Contact Locations

4.1.2 Cryptographic Key Loading. Cryptographic keys are loaded through the AN/PSN-11 J1 connector (refer to Figure 4-1).

5.0 DATA INTERFACES (J2)

5.1 Physical Interface. Data interfaces use the AN/PSN-11 J2 connector.

Data interfaces include TOD output, 1PPS precise time input/output, external reprogramming, National Marine Electronics Association (NMEA) 0183 output, remote OFF signal, and bi-directional RS-232/RS-422 serial data. The data port J2 connector and its mate are identified in Table 3-1. Cables supplied for connecting the AN/PSN-11 to a HAVE QUICK radio, a personal computer, or another AN/PSN-11 are identified in Table 3-2. Figure 5-1 illustrates J2 contact locations. See Section 8 for the location of J2 and connector clearance when the AN/PSN-11 is within the installation mount.

Figure 5-1. AN/PSN-11 J2 Contact Locations

5.2 Electrical Interface. Electrical characteristics are provided in Table 5-1.

5.2.1 TOD Interface. This description of the TOD interface is intended to reflect the actual operation of the PLGR, and is provided to ensure interoperability with HAVE QUICK radios that have previously used the PLGR as a source of time synchronization. Compliance with this interface description does not guarantee interoperability with all radios implementing the HAVE QUICK frequency hopping algorithm. Refer to Table 5-1 for electrical characteristics.

5.2.1.1 Message Format.

5.2.1.2 Bit Stream. The signal transmission is comprised of a series of 400 logic 1 pulses, followed by 112 data pulses (logic 1 or logic 0). The duration of the transmission is 307.2 ± 1.0 msec, and the bit rate is approximately 1667 bits per second.

5.2.1.3 Message Structure. The message structure consists of, in order, 400 synchronizing pulses, two start-of-message bytes, hours, minutes, seconds, day of year, year, and Time Figure of Merit (TFOM). Each of the time and TFOM bytes consists of a nibble of parity together with a nibble of data in Binary Coded Decimal (BCD) format. The message structure is shown in Table 5-2.

5.2.1.4 Parity Structure. The parity nibble that is generated is unique for each nibble of data, and the parity with the data forms a modified Hamming Code byte. For the receiving equipment, this code allows detection and correction of a single bit error. The code also allows detection, but not correction of two bit errors in any byte. Refer to Table 5-3.

5.2.1.5 Message Timing. The TOD message is timed to have the rising edge of the first of the 400 logic 1 bits to start at the coordinated universal time (UTC) 1 second roll over. When the TFOM is 5 to 1, the accuracy is within 10 µsec.

6 7 8 9 10

11 12 13 14 15

5-2

5.2.1.6 TOD Enabling. The TOD transfer is accomplished with the PLGR powered on, receiving satellites, and connected to a compatible HAVE QUICK transceiver. The HAVE QUICK TOD message is enabled via keypad or serial data interface command. Thereafter, at each 1-second boundary, a data transmission will occur, if the TFOM is 7 to 1. If the TFOM is 8 or 9, the data output is withheld.

5.2.2 1PPS. The 1PPS interface electrical characteristics are described in Table 5-1.

5.2.3 Remote ON. The Remote ON interface electrical characteristics are described in Table 5-1.

5.2.4 External Reprogramming. The external reprogramming voltage characteristics are described in Table 5-1. This signal is used to clear the AN/PSN-11 erasable programmable read-only memory (EPROM) during reprogramming.

Reprogramming data itself is sent to the AN/PSN-11 using the RS-232 or RS-422 serial data ports in accordance with the protocol described in ICD-GPS-153.

The AN/PSN-11 reprogramming cables described in this IS use only the AN/PSN- 11's RS-232 serial data port.

5.2.5 NMEA 0183. The NMEA 0183 interface is described in ICD-GPS-153.

5.2.6 RS-232/RS-422. The RS-232/RS-422 serial data electrical characteristics are described in Table 5-1.

5.3 Cables. Tables 5-4 through 5-8 contain wire lists for the standard cables used with the AN/PSN-11. Figures 5-2 through 5-7 illustrate the standard cables.

6.0 EXTERNAL ANTENNA INTERFACE (J3)

6.1 Physical Interface. The antenna interface transfers radio signals to the AN/PSN-11 from the antenna and transfers power to the antenna from the AN/PSN- 11 using the AN/PSN-11 connector J3. The antenna interface J3 connector is defined in Table 3-1. See Table 3-2 for the remote antenna cable National Stock Number (NSN). See Table 3-3 for supplied antennas NSNs and part numbers.

6.2 Electrical Interface. Electrical characteristics of the J3 connector are provided in Table 6-1.

Table 6-1. J3 - Antenna Interface Electrical Characteristics

6.3 Antenna Characteristics. Table 6-2 describes the minimum performance characteristics of the external antenna. These characteristics may be used to determine GPS receiver performance characteristics when interfacing to existing remote antennas.

For purposes of this document, it is assumed that the antenna consists of one or more antenna elements and an associated self-contained ground plane, RF filtering and amplification as needed to meet requirements, an appropriate enclosure (radome), and a single antenna-to-receiver interface cable.

The antenna provides for the reception of right-hand circularly polarized (RHCP) radiated signals from the NAVSTAR GPS satellites and outputs them to the receiver. Antenna gain is measured in decibels referenced to the gain of an ideal, lossless, RHCP, isotropic antenna (dBic). The antenna provides RHCP signal reception over a minimum solid angle cone of 160 degrees.

6.4 Antennas and Cables. Figures 6-1 through 6-4 illustrate the helmet antenna and cable, AN/PSN-11 to remote antenna cable, remote antenna, and aircraft antenna. Figure 6-5 illustrates the envelope that will fit within the Paladin antenna housing.
