Description: ISS attached or Free-flyer Multichannel VHF / UHF transponders Multimodes: Voice, Telemetry,Video, Image, Data, Msgs Ground Stations: Internet-linked Global Volunteer network Off-the-shelf, low-cost ($100 to $200) transceivers Downloadable software defined sound-card modems Open-ended experimental bandwidth Complementary Experiments: ODTML – Ocean Data UHF RFI Mitigation MIDN – Human physiology Radiation Detector SCIENCE (USNA-0203)Experiment Concept ! Objective: • Education of future Naval Officers in Space Programs and Technology • Low cost 1200/9600 baud telemetry bus for STP Experiments • Experimental UHF transponders for DOD & student education/training OR • Previous Priority: • 43 of 43: 2005 DoD SERB 2006 DoD SERB

  3. SCIENCE (USNA-0203)Technology & Development ! Major Instrument or Equipment: • ODTML • UHF RFI Mitigation Receiver • Multiple UHF transponders • Multiple modes (voice, data, TDMA FDMA) • Supports additional experiments (1200/9600 bd) Instrument or Equipment Operation: • Educational Experiments/Communication • Science data from attached experiments • Remote Sensor Data Relay Experiment Funding: Hardware Status: • Technology is Mature • Technology is Space proven on PCSATS • CDR: Spring 2007 • Flight Ready: Spring 2008 2006 DoD SERB

  4. SCIENCE (USNA-0203)Military Relevance Military Needs: • Support additional STP experiments (1200/9600 baud links) • ODTML, MIDN, UHF RFI Mitigation Receiver • Education of Midshipmen and Space Cadre in Space Applications • DOD Schools: Service Academies (4) Graduate Institutions (3) ROTC Units (550 Schools) • DOD Comms Cadre: Civil Air Patrol (1800 units) Military Affiliate Radio Stations (8000) US Coast Guard Auxiliaries (33,000) Ocean Buoys w/ RF Terminals GROUND STATION Documentation:USSpaceCom Long Range Plan, p77-79 2006 DoD SERB

  5. Experiment / Flight Data: Attached payload or Free-flyer Apogee: 400 to 800 km Perigee: 400 to 800 km Inclination: 20 to 98 deg (lower if higher) Physical Data: 0.25m3, 25 kg, nominal 50 W Shuttle/ISS Required: [No]: Acceptable: [Yes] Experiment Retrieval Required: [No] Repetitive/incremental step flights: [No] SCIENCE (USNA-0203)Flight Requirements ! • Need for Spaceflight • ODTML and UHF RFI coverage • Communications Orbit for Global coverage and range Requested STP Services • Launch Services • Launch Integration 2006 DoD SERB

  6. SCIENCE (USNA-0203)Data Application Plan ! • Data Application Plan • Real-time data collection and distribution by existing internet linked system • No cost Operations by volunteer ground stations and other schools and universities • Transparent data relay, collection, distribution. Independent of system operation • Only sender and receiver of data need to collaborate • WEB Browser access to all data 2006 DoD SERB
