Requirements Title: 13 Meter SGLS/US B/X- Band Auto-tracking Antenna System with Installation and Radome

Background: The NRL is interested in procuring a full motion 13-meter S and L band (1750-1850 and 2200-2300 MHz) antenna with Unified S-band (USB) capabilities in both the transmit and receive as well as the full X-band receive capabilities in the 7600-8500 MHz bands. An antenna system that is a full motion antenna, commercial item, and that has been engineered to meet the performance requirements in the attached document. These requirements are unique with the Department of Defense and are required to meet the mission requirements. More specific information is listed below.

Specifications/Characteristics:

2.1.1 ANTENNA SYSTEM REQUIREMENTS:

2.1.1.1 Track, receive, downconvert and demodulate telemetry in S-Band 2200 to 2300 MHz.

Downconversion of telemetry is an antenna capability requirement; however the downconverters in the antenna are not required.

2.1.1.2 Track, Receive, downconvert and demodulate EOS Data in the X-Band 8025 to 8500 MHz. Downconversion of telemetry is an antenna capability requirement; however the downconverters in the antenna are not required.

2.1.1.3 Modulate, up convert, power amplify and transmit commands in both the L and S band, selectable, 1763 to 1840 MHz and 2025 to 2110 MHz with a minimum EIRP of 93 dBm

2.1.1.4 Antenna feeds polarizations for L and S Band shall be selectable for Right or Left hand Circular polarization

2.1.1.5 Antenna Feed polarization for X-band shall be simultaneous Left and Right Hand Circular Polarization with an Axial Ratio of <1 dB

2.1.1.6 Antenna feed section shall have provisions for adding band pass or notch filters.

Requirements are to be determined. X-band feed shall include a band pass filter to limit operational band to 8025-8400 MHz,

2.1.1.7 All waveforms must meet National Telecommunications and Information Administration (NTIA) mask requirements.

2.1.1.8 Ability to auto track on the S and X band receive signals with automatic switching to X-band when it is present. The Auto track system shall maintain tracking within a 1 dB beamwidth.

2.1.1.9 Coupled test ports for injecting test signals into the S and X band receive path and for monitoring the L and S band Uplink path.

2.1.1.10 Optimize to operate at the highest velocity that is electrically and mechanically possible to minimize the Keyhole effect on contacts that are tracked directly over the antenna site.

2.1.1.11 Track 0 to 180 degrees in elevation and +/- 360 degrees in azimuth

SALIENT CHARACTERISTICS

2.1.2 GROUND STATION ELECTRONICS

2.1.2.1 Operate on 120/208V, 60Hz, 1 or 3 Phase electrical power or on 480V, 60Hz 3 Phase electrical power, to be compatible with current power supplied by the host site.

2.1.2.2 Capability for antenna-pointing schedule

2.1.2.3 Provide the capability for the ground system to automatically generate the system G/T

2.1.2.4 Provide for the ability of any hardware errors, failure warnings or alarms to be monitored remotely through a machine to machine interface protocol via Neptune

2.1.2.5 To accommodate cyber security compliance, all machine to machine interfaces must meet or exceed SNMP v3 standards

2.1.2.6 Provide all status and control as displayed on the front panel of equipment to be accessible via software interface for use in Neptune for remote control and monitoring.

2.1.2.7 Where possible, provide a useful life of > 10 year, assuming normal operating environment, normal maintenance, sparing and recapitalization. Any equipment with <10 years useful equipment life cycle will be approved by the government prior to purchase.

2.1.2.8 Provide an overall mean-time-between-failure (MTBF) of the equipment

2.1.2.9 Provide a mean-time-to-repair (MTTR) of the equipment

2.1.2.10 Support IA certification and accreditation in accordance with the Cyber Security Plan.

2.1.2.11 Provide the capability for remote diagnostics and maintenance of hardware and software via remote login.

2.1.2.12 Provide the ability to remotely power on/off the equipment

2.1.2.13 Capability to fly-wheel (operate while communications is lost with the Blossom Point

Track Faciltit SOC) for TBD minutes/hours.

Estimated Delivery Date: Delivered within 13 months through site acceptance testing.
