Psat (USNA-0601) Experiment Concept

• • • • •

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 Description: Free-Flyer /Piggyback

• VHF Data Transponder – Remote Data Relay – w Global Internet Gateways – Draw from education experimenters – Scaleability and Constellation – 9 dB link advantage to UHF – Using low cost COTS • Bus support for other Serb Payloads – ODTML UHF transponder – UHF RFI Mitigation – MIDN Radiation Sensor (usna) – Dragon particle detector (usna)

Previous Priority:

•48 of 51 DoD •30 of 30 DoN 4/27/2020

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

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

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 m 3 , 20 kg, nominal 20 W • Shuttle/ISS Required: [No]: Acceptable: [No?] • Experiment Retrieval Required: [No] • Repetitive/incremental step flights: [No] 4/27/2020

Background P-SAT (USNA-0601) Intro and Background

 Psat transponder can draw from thousands of experimenters for large scale experiments. A larger spacecraft can support other small SERB experiments.

4/27/2020   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.
