58 -- TRANSLATED GPS RANGE SYSTEM (TGRS) POC Lee Powell, Contract Specialist, 904/882-8601, Ext 317 Tanya Lambert, Program Manager, 904/882-8601, Ext 352 Craig Pope, Contracting Officer, 904/882-8601, Ext 315. Aeronautical Systems Center, Weapons, Air Base and Range Product Support Organization, Range Applications Joint Program Office (RAJPO) is considering the acquisition of a Translated GPS Range System (TGRS) to provide Time-Space-Position-Information (TSPI) for high dynamic participants in Department of Defense (DOD) test and training missions. Because of the near term requirement for the TGRS capability maximum use of commercial 0ff-the-shelf items is encouraged for the development of the system components. 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 SV signals. When properly configured, it shall also provide for the secure transmission of host vehicle wideband telemetry information. This segment shall consist of the Digital GPS Translator (DGT) with an optional Power Booster Unit (PBU). 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 may consist of either: 1) a relay translator which receives and retransmits participant segment signals for processing by the range segment, or 2) a translator processor which provides a real-time TSPI state vector for vehicles equipped with participant segment components and relays 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 GPS Translator Processor (GTP), a Mission Control Console (MCC), a Predetect Signal Recorder (PSR), and an antenna/preamplifier. The basic requirements of TGRS are as follows: 1) to provide the capability for enhanced post-flight trajectory analysis on tests involving intercept and kinetic kill impact of a target vehicle nearing the terminal phase of a ballistic trajectory. Tracking of both the target and interceptor is required. TGRS participant segment components will be mounted in both vehicles to provide retransmission of translated GPS signals and vehicle telemetry for subsequent reception and processing for position data by remote land based TGRS range system components. This data may be required for both vehicles from lift-off until the impact event; 2) to provide the capability for line-of-sight and over-the-horizon (via relay aircraft) range safety tracking for the Advanced Medium Range Air to Air Missile (AMRAAM) as a subsystem to the Next Generation Target Control System (NGTCS). TGRS participant segment components will be mounted in the AMRAAM to provide retransmission of translated GPS signals and AMRAAM telemetry for subsequent reception and processing for position data by remote TGRS range segment components. This data will be required from weapon launch until weapon impact. Additionally, the TGRS may provide enhanced post-flight trajectory analysis. This Sources Sought Synopsis is for planning purposes only and shall not be considered an IFB or an RFP and is not to be considered as a commitment by the Government. The program office plans to schedule and conduct one-on-one dialogues with interested prime contractors who have existing candidate systems that meet the TGRS requirements and who respond to this Sources Sought Synopsis within 20 days. These individual dialogues are to answer questions, regarding the TGRS technical and schedule requirements, and to discuss offerors recommendations for a draft RFP. The Government plans to release the RFP in August 1995. The Government reserves the right to award without discussions. The TGRS capability needs to be operational starting in early 1997. Information associated with this program may be classified up to and including Secret. All potential contractors will be required to obtain export control certification from the Defense Logistics Services Center (DLSC), Battle Creek, MI 49017-3034 (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. 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 extension 317. Such information should include and briefly describe plant, professional, and manufacturing resources, knowledge of the technologies involved, experience with global positioning systems and description of the firms candidate system and what vehicles/conditions the system has been integrated into/tested under. Information sought includes size, weight, and power requirements, environmental testing completed (vibration and temperature), Mean Time Between Failure (MTBF), Dynamics, State Vector Update Rate, and Data Latency. Acknowledgment of receipt of responses will not be made nor will evaluation of information provided be given. Firms wishing to be considered for this effort and desiring further information, and to schedule a one-on-one dialogue with the Government team should contact Tanya Lambert, ASC/VXG 904-882-8601 extension 352. No collect calls. Responses to this notice must be received no later than 20 calendar days after publication in the Commerce Business Daily. (0107)
