  1. WALLOPS FLIGHT FACILITY ELECTRICAL ENGINEERING BRANCH CODE 569 LOW COST TDRSS TRANSCEIVER (LCT2) PROGRAM REVIEW APRIL 2004 Wallops Flight Facility - Code 569

  2. Agenda • Program Overview • Program Team • Background • Current Task Scope • Technology • Schedule • Flight Tests Wallops Flight Facility - Code 569

  3. Program Team Wallops Flight Facility - Code 569

  4. LCT2 Background & Objectives • Utilize space based communications assets for over the horizon range tracking activities • Lower launch costs by minimizing down range tracking assets • Provide increased range availability • Enable remote/austere launch operations • NASA’s Tracking and Data Relay Satellite System (TDRSS) provides S-, Ku-, and Ka-Band space based data communications • TDRSS has been historically used by government satellites and high altitude balloons • Presently TDRSS communication flight hardware is very costly • LCT2 is an effort to make TDRSS communications flight hardware more economical and less intrusive for flight vehicles with low weight and power margins Wallops Flight Facility - Code 569

  5. Current Program Task • Design a TDRSS transceiver that can be transferred to industry to enable future range operations cost savings and enable rapid response range operations. • The goals are: • Develop a transceiver design compatible with the TDRSS S-Band forward link and DG1 mode 2, DG2 return link formats • Develop prototype units for demonstration on sub-orbital platforms, including sounding rockets, long duration balloons, and UAV’s • Develop low cost solution for technology transfer to industry for future commercial production • Lower cost from $250K per Transceiver seen today to $75K per Transceiver Wallops Flight Facility - Code 569

  6. LCT2 Technology • LCT2 is leveraging • DSP Technology from Satellite Cross Link Simulator development from Goddard Space Flight Center • Autonomous Flight Safety System (AFSS) GPS and INS technology from NASA’s Wallops Flight Facility and Kennedy Space Center • Inertial Navigation System – INS • Global Positioning System – GPS Wallops Flight Facility - Code 569

  7. LCT2 System Wallops Flight Facility - Code 569

  8. Development Status • Upcoming Tasks • Integration & Test • TDRSS Compatibility Test • Thermal & Vibration Testing • Flight Test • Performance Evaluation • Continue Flight Testing when available • Integrate GNP-10/LCT2 Package • Thermal Analysis • 30 Watt Transmitter Development • Flight Test • 30 Watt Transmitter – June 2003 to March 2005 • Completed Tasks • Requirements Analysis • Trade Studies • Prototype Design • Prototype Fabrication • Prototype Testing • Mechanical & Thermal Analysis • Production Unit Design • In Progress • Production Unit Layout • 12 Watt Power Amplifier Design Wallops Flight Facility - Code 569

  9. Development Status • Receiver– June 2004 to December 2006 • Completed Tasks • Requirements Analysis • Upcoming Tasks • Trade Studies • Prototype Design • Prototype Fabrication • Prototype Testing • Mechanical & Thermal Analysis • Production Unit Design • Production Unit Layout • Integration & Test • TDRSS Compatibility Test • Thermal & Vibration Testing • Flight Test • Performance Evaluation • Continue Flight Testing when available • Thermal Analysis post Flight Test Wallops Flight Facility - Code 569

  10. Program Schedule Wallops Flight Facility - Code 569

  11. Flight Test Schedule • Flight Test #1 July 2004 • Transmitter – 12 Watt • Bit Error Rate Test • Flight Test #2 June 2005 • Transmitter – 30 Watt • Metric Tracking Package (GNP10, IMU - Inertial Measurement Unit) • Metric Tracking Test • Flight Test #3 January 2006 • Transceiver – 30 Watt • Forward Link Test • Flight Test #4 June 2006 • Transceiver – 30 Watt • Metric Tracking Package (GNP10, IMU) • Flight Demonstration December 2006 Wallops Flight Facility - Code 569

  12. Flight Cost Estimate • $60K per Flight Test Includes: • Flight Hardware • Mounting Deck • LCT2 • Antenna • TDRSS Network Operations Support • Sounding Rocket vehicle costs shared by multiple users • Can piggyback on technology demonstration flights sponsored in part by Sounding Rocket program Wallops Flight Facility - Code 569
