70 -- HARDWARE Sol F33600-95-R0069. POC For additional information, contact Pam Strader, ASC/PKWRE/(513)257-2698. The National Air Intelligence Center (NAIC), Wright-Patterson AFB, Ohio, has a requirement for a system to collect data and perform real time monitoring of the GLONASS and GPS satellite constellations. The contract will purchase, install and maintain the receiver. The objective of this contract is to obtain a 3S Navigation R-101 L1/L2 GLONASS Receiver that will be used as the only tool for SpaceSignals Analysis Branch. The equipment must be capable of receiving GLONASS P-Code at L1 and L2 frequencies. The receiver must have multi-channel capabilities in order to collect data on multiple satellites at one time. It must output pseudorange and raw hexadecimal broadcast data to be compatible with current analysis software. It must have a compatible interface with the current Signals Exploitation Division's VAX computer network. 1. General Specifications are: a) 6-channel GLONASS P-Code receiver; b) GLONASS and BPS C/A-Code available; c) L1/L2 GLONASS AND L1 GPS antenna; d) Software to manipulate data into usable format; e) Pseudorange and raw hexadecimal data output; f) Environmental rugged antenna; g) VAX network interface; h) Timing reference input/output; i)Screen capture software; j) C2 security accreditation software; k) Data format and processing software compatible with other existing government receiver locations; and 1) IBM PC/AT compatibility. 2) Detailed Specifications are: a) 6-channel GLONASS P-Code receiver with combination of L1 and L2 frequencies; b) 12-channel GLONASS C/A-code or 6-channel GPS C/A-code or combination of the two available at L1 frequencies; c) Antenna must have range between 1240-1620 MHz to collect L1/L2 GLONASS and L1 GPS signals; d) Proprietary software applies digital signal processing techniques to received signal in order to read data; e) Data output formats: (1) Raw pseudoranges, integrated carrier phase measurements and associated RMS errors; (2) Carrier-smoothed pseudoranges and associated RMS errors: (3) Carrier-to-Noise ratios; and (4) Broadcast GLONASS data, Hexadecimal format; f) Antenna operable in temperature range between -25 degrees and +70 degrees C and 100 degrees humidity. Storage temperature range between -25 and +85 degrees C; g) Ethernet interface cared and telnet software for high-speed communication with VAX network; h) Timing output referenced to GLONASS time. Timing input available to connect high performance atomic standards; i) Screen capture software to print scatter plots generated by receiver; and j) Security accreditation software providing C2-level security and full compliance with Defense Intelligence Agency (DIA) Security Concept of Operations. NAIC is contemplating a sole source contract with 3S Navigation in Laguna Hill, CA. Solicitation will be issued approximately 30 Jan 95.
