A -- DESIGN, DEVELOPMENT, AND DELIVERY OF TRANSLATED GPS RANGE SYSTEM (TGRS) EQUIPMENT POC Mr. Lee Powell, Contract Specialist, 904/882-8601, Ext 317 Ms Tanya Lambert, Program Manager, 904/882-8601, Ext 352. Design, development, and delivery of the Translated GPS Range System (TGRS). This announcement is the precursor to the release of the Draft Request for Proposal (DRFP) for the TGRS. The contractor shall deliver equipment as indicated: Digital GPS Translators (DGTs) to various Department of Defense (DOD) Users and Ranges, GPS Translator Processors (GTPs) to various DOD Users and Ranges. Options to the contract will provide DGTs, GTPs, predetect recorders, repair kits, field engineering support, etc., to various DOD Users and Ranges. The TGRS shall meet the following requirements: 1) shall be capable of operation in ballistic or tactical missile host vehicles subjected to 100 g acceleration (goal is 150 g acceleration), 100 g/sec jerk (goal is 150 g/sec jerk), and 30,000 ft/sec velocity, The TGRS shall be composed of three major elements: the Participant Segment, the Relay Segment, and the Range Segment. The Participant Segment shall be mounted in a missile or other host vehicle under test. This segment shall provide accurate reception, frequency translation, digitization, and encryption of GPS Satellite Vehicle (SV) signals. This segment must also provide for secure transmission of other host vehicle telemetry signals (up to 16 Mbits/sec) in addition to and merged with transdigitized GPS signals with a maximum data rate of up to 20 Mbits/sec. The combined data rates will not exceed 20 Mbits/sec. This segment shall consist of the DGT and Power Booster Unit (PBU) whose combined size shall not exceed 10 cubic inches. The Relay Segment shall be mounted in an airborne relay platform. This segment shall provide an over-the-horizon (OTH) link between the participant segment and the range segment. This segment shall consist of a GTP which receives and processes participant segment signals, provides real-time TSPI state vectors for the host vehicles and transmits this data to the range segment. The Range Segment shall be mounted at a fixed reference ground site, or optionally in an airborne or shipborne reference vehicle. This segment shall provide real-time TSPI for participant vehicles by processing line-of-sight (LOS) translated GPS signals from participant segment components and OTH relayed signals from the relay segment components. This segment shall also provide enhanced post-flight trajectory analysis for participant vehicles by processing LOS translated GPS signals. This segment shall consist of the GTP, a Mission Control Console (MCC),a Predetect Signal Recorder (PSR), and a reference receiver antenna/preamplifier. The TGRS must satisfy the following key technical requirements and characteristics: (a) shall provide real-time and post-mission GPS dual band (L1/ L2) processing and secure signal transmission from host vehicle to the GTP, (b) shall be capable of supporting digital translators (goal is analog and digital), (c) shall be capable of detecting and eliminating unhealthy GPS satellites from the real time state vector solution, (d) shall be capable of all-in-view GPS satellite tracking, (e) shall be capable of real time processing of tracked vehicle state vector updates at a selectable 1, 10 or 20 times per second, (f) under the maximum dynamics listed above, shall provide real-time state vector solution accuracy not to exceed 9.0 m horizontal position, 16.0 m vertical position, 2.0 m/sec horizontal velocity, and 3.3 m/sec vertical velocity, (g) under more benign dynamics (10 g/sec jerk), shall provide real-time state vector solution accuracy not to exceed 4.1 m horizontal position, 6.8 m vertical position, 0.15 m/sec horizontal velocity, 0.25 m/sec vertical velocity, (h) under the maximum dynamics listed above, shall provide sub-meter accuracy enhanced post-mission trajectory analysis, (i) shall simultaneously acquire and establish track of multiple (4 required, 8 is goal) vehicles with the dynamic vehicle tracking accuracies specified above within 3 seconds of launch without prior knowledge of nominal or actual vehicle position and velocity, (j) shall be capable of accepting and outputting baseband signals from the tracked vehicle to and from a predetect recorder, (k) the GTP shall be capable of accepting data concurrently from both right-hand and left-hand circularly polarized S-band antenna feeds, aligning the pilot carrier phases, selecting the better signal in real time, and recording the two signals independently, (l) shall meet EMI/EMC requirements, (m) the GTP shall be a maximum of 10 inches in height and be configured to mount in no larger than a standard 19-inch rack, (n) the GTP shall be equipped with a self-contained P-code GPS reference receiver, (o) shall be designed as a turn-key system, (p) shall have the capability of post mission processing of recorded mission data, (q) shall be .999 reliable, (r) the GTP shall be capable of receiving and processing translated GPS S-band signals from 2200 to 2400 Mhz in 1 Mhz steps with polarization diversity, (s) shall have selective availability/anti-spoofing (SA/A-S) capability, (t) shall be capable of supporting host vehicle L-band patch (switching) antenna configurations, (u) shall be supportable under a two-level maintenance program, (v) shall be capable of being remotely configured and operated except for data retrieval to a removable storage medium, (w) shall be capable of simultaneously tracking multiple host vehicles in flight. A technical data package is not available. Interested sources must demonstrate the following capabilities: (a) Delivery schedule is of the essence. System must be qualified and delivered by October 1997 to support planned user testing in the 3rd quarter FY98, (b) Must have developed and utilized Translator Processing Systems in the support of Government tests which used GPS translators to track ballistic objects in space, (c) Must have total system and product support capabilities (e.g. reliability, manufacturing and producibility, human engineering, logistics support analysis, training and technical manuals). (d) Must have proven capability to conduct formal program, technical, and test reviews (e.g. Preliminary Design Review, Critical Design Review, Functional Configuration Audit, Test Planning Working Group). (e) Must have a quality control and quality assurance system in place. (f) Must have an in-place field service organization to provide up to three years of product support for equipment delivered to Department of Defense ranges. The contractor shall provide on-call field engineering and technical support to the Government in order to operate and maintain the TGRS equipment located at the applicable ranges. The contractor shall supply all labor, services, supplies, support equipment, and technical data. Firms requiring associated data are to provide names of personnel requiring access and validate their capability to receive Scientific and Technical Information (STINFO) under 22 U.S.C. 2751 and U.S.C. 50 Appendix 2401. It is unlawful to export items containing export controlled technical data. Potential contractors will be required to obtain certification from the Defense Logistics Services Center (DLSC), Battle Creek MI 49016-3412, telephone 1-800-352-3572 in accordance with DOD 5230.25 prior to being provided access to unclassified data. Certification is accomplished using DD Form 2345, Military Critical Technical Data Agreement. This requirement for DD Form 2345 certification also applies to any subcontractors being given access to reproduced data by another contractor. It is not the intent of the Government to obtain proprietary information by means of this synopsis. Any hardware or services which the Government may elect to procure as a result of responses to this announcement will be announced separately. All documents for TGRS will be available in Microsoft Word 6.0 on the Eglin Bulletin Board for downloading by potential bidders. The Eglin Bulletin Board telephone number is (904) 882-5310. Information and particulars to document your capabilities and qualifications to satisfy the TGRS effort must be submitted to ASC/VXGK, ATTN: Lee Powell, 904-882-8601 Ext 317.
