TRI-SERVICES EXPERIMENTS CONTRACT (TSX-6)

FOR THE AIR FORCE SPACE TEST PROGRAM

DATE

  1. TSX-6 PROGRAM OBJECTIVES

  1. Introduction. Tri-Service Experiment Mission 6 (TSX-6) supports the Space Test Program (STP) charter by providing Department of Defense (DoD) experiments access to space. TSX-6 will host at least two DoD experiment packages: the OPREX Spacecraft Evaluation Module (OSEM) and the Polymer Battery Experiment (PBEX).

  1. TSX-6. The primary objective of this mission is to collect data from the OSEM, PBEX, and any other experiments in accordance with their requirements documents. The TSX-6 spacecraft (SC) will be commanded and controlled via stand-alone ground control stations located at the SC contractor and experimenter facilities. The SC will downlink OSEM and PBEX payload data to the ground control stations. Initial Launch Capability (ILC) is expected to be approximately November 1999.

  1. OSEM. OSEM will collect and evaluate a data base of selected, scientific information associated with small communications signal links between spacecraft and ground stations. The experiment utilizes and evaluates several modulation and detection techniques under a variety of natural, man-made, earth, and deep space interference conditions. Experiment data will assess and quantify communications phenomena and will be instrumental in determining the frequency and power density required to optimally perform closed-loop communications.

  1. PBEX. PBEX will evaluate the performance of advanced all-plastic batteries in space by measuring the performance of a test battery during alternating charge and discharge cycles. The plastic battery is rechargeable, utilizing a plastic anode, cathode, and gel electrolyte.

  1. Period of Performance. Basic contract for maximum of 24 months from contract award to initial launch capability. Two 24 month contract options for two similar spacecraft to support experiments to be specified by the government.
  2. Mission Life. Design, build, integrate, and test space vehicle for a 90% probability of 3 year life. The design goal is a mission life of 5 years.
  3. Ground Stations. TSX-6 will not use the Air Force Satellite Control Network (AFSCN), but option vehicles may require compatibility with the AFSCN. Design, build, integrate, and test three stand-alone ground control stations with encrypted RF communications capability. Design, build, test, and integrate ground control software.
  4. On-orbit Checkout. Perform early orbit operations checkout.
  5. Training. Develop training and operations manuals for experiment agency and associated contractor personnel; perform handover training and execution. After on-orbit checkout, spacecraft and experiments will be operated by the experimenter.
  6. Anomaly Support. Provide on-call support during the on-orbit phase of the program.
  7. Insight. Provide sufficient government insight into design capability, reliability, and availability to support government confidence in mission success and to support Mission Risk Assessments, Mission Readiness Review, and Flight Readiness Review.
