Objective:

Design, develop, and test a reentry body antenna or antenna system capable of transmitting high speed, real time, inflight, encrypted data. The data transmission should be in bands alternate to S band such as the K & Ka bands and communicate with geostationary satellites used as a pass-through mechanism to relay the encrypted data to ground.

Description:

The development of a next-generation telemetry communications antenna for Navy Submarine Launched Ballistic Missile (SLBM) reentering test bodies is critical in advancing developmental technologies being evaluated on flight tests. While common ground tests such as wind tunnels, arc jets, and vibration provide insights into predictable reentry environments, flight testing remains the gold standard in evaluating reentry bodies (RBs) and their onboard technologies. Flight tests evaluate a reentry body’s ability to withstand the harsh and sometimes unpredictable environments of flight to include launch, separation, and reentry.

The current technology to monitor SLBM payloads during flight include a transmitter/receiver system between the reentry body and ground stations. Data is captured during flight and transmitted to the ground in the S band (2-4 GHz), making data transfer slower than higher frequency bands [Ref 3]. Due to the S band being a highly populated frequency band and the power on the RB required to telemeter data in the S band back down to the ground receiver, midflight data transmission is both slow and costly. Additionally, since the transmitter/receiver system today is only between the RB and ground station, real time data transmission is lost during a portion of the flight when the RB is the furthest away from the ground, otherwise commonly known as “over the top” of the flight trajectory as well as during reentry when the body enters plasma blackout. To solve this problem, the technology proposed should use alternate frequency bands, such as K and Ka bands (18-40 GHz) and make use of geostationary satellites as a pass-through mechanism to capture real time data from the RB and telemeter the encrypted data back down to the ground at high speeds in order to minimize data transmission latency and loss. The use of alternate frequency bands allows for high data rate information exchange [Ref 1]. This new technology would solve the issue of losing real-time data transmission midflight.

By having real-time, high-speed data throughout the duration of flight on a flight test, the Navy can better understand technology performance throughout the various environments and environment transitions and can more effectively diagnose issues or failures resulting in faster technology maturation.

Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by 32 U.S.C. § 2004.20 et seq., National Industrial Security Program Executive Agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain at least a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and SSP in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.
