Objective: • Education of the future Navy Space Cadre… • Transponder for low cost data exfiltration. • Low cost COTS Solar Panels for Responsive Space • Low Cost Cubesat Launch and bus system • Small AUX Payload space for small SERB experiments • Previous Priority: • 48 of 51 DoD • 30 of 30 DoN • Complementary Experiments: • Provides continuity to xponders of PCSATs, ANDE, RAFT, GO-32etc • Common AX.25 protocol at 1200/ 9600 baud • Off the shelf $500 RF systems exist and space proven. $30 solar panels 2008 DOD SERB

  5. Psat USNA-0601 CUBESAT Deployment Midn Ridge 2008 DOD SERB

  6. Major Instrument or Equipment: Psat VHF transponder for data exfiltration Educational “Force Tracking” Bus support for other small SERB experiments Instrument or Equipment Operation: Dual uplink TDMA data receivers Aloha, Slotted Aloha, and file store/forward Low cost COTS solar panels for responsive space Low cost CUBESAT for multiple opportunities Sun pointing for lower cost solar power system Low cost attitude control +/- 40 degree requirement Psat (USNA-0601)Technology & Development ! Experiment Funding: Hardware Status: • All technologies are mature and off the shelf • Have space heritage (PCSAT, ANDE, RAFT) • PDR: Fall 2008 • Flight Ready: Fall 2009 2008 DOD SERB

  7. Psat (USNA-0601)Military Relevance ! Military Needs: • Education and experience for future naval officers in the space cadre • 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) • Data Exfiltration and service to low power/low-priority users • Tactical situational awareness and constellation support • COTS testing for Responsive Space & other small SERB experiments Ocean Buoys w/ RF Terminals GROUND STATION Documentation: • USSpaceCom Long Range Plan, p77-79 – education- space cadre • NDAA (P.L. 104-201) Directs …Ocean Research and Sciences • CNA study (June 04) identifies data exfiltration requirement 2008 DOD SERB

  8. Experiment / Flight Data: Free-Flyer or Piggy-back or cubesat Apogee/Perigee: 400 to 800 km (>5 yr life) Inclination: 20 to 98 deg (lower, if higher) Physical Data: .02 m3, 20 kg, nominal 20 W Shuttle/ISS Required: [No]: Acceptable: [No?] Experiment Retrieval Required: [No] Repetitive/incremental step flights: [No] Psat (USNA-0601)Flight Requirements ! • Need for Spaceflight: Medium is the message • Future Officer Aerospace Education – space cadre • Remote Data Relay requires Comms orbit. • Space Performance of COTS required • Space environment needed for aux payloads Requested STP Services • Launch Services • Launch Integration 2008 DOD SERB

  9. Psat (USNA-0601)Technology Transition/Data Application Plan ! • Data Application Plan • Data from all experiments available live via Internet from global ground stations • AX.25 Data/formats handled transparently by Satellite and Global Infrastructure • New-User, New Experiment, New Data transparently accommodated instantly. • Global infrastructure tied into Google maps and satellite images • Global infrastructure has existing WEB telemetry displays built-in. 2008 DOD SERB

  18. P-SAT (USNA-0601)Intro and Background Background • Psat transponder can draw from thousands of experimenters for large scale experiments. A larger spacecraft can support other small SERB experiments. • Multiple transponders on smaller picosats can form a constellation for greater coverage and reduced latency. • Not only the sensors and users exist, but the global Internet collection and distribution system also exists from PCSAT1 & 2. 2008 DOD SERB
