STPSat 5 [SNC]
STPSat 5 is a planned experimental spacecraft for the Department of Defense's Space Test Program (STP).
STPSat-5 will carry a total of four technological or scientific payloads to low-Earth orbit in order to further the DoD�s understanding of the space environment. The experiments are chosen by the DoD Space Experiment Review Board.
The satellite is based on SNC's SN-50 bus, which is compatible both with dedicated launch vehicles and ESPA-class secondary launch adaptors.
Following experiments were on board:
- The Strontium Iodide Radiation Instrumentation (SIRI) experiment, produced by the Naval Research Laboratory (NRL) sought to demonstrate a new gamma radiation sensor in space.
- The Ram Angle and Magnetic field Sensor (RAMS), also from the NRL, was developed to demonstrate a new attitude determination sensor for small missions.
- The integrated Miniaturized Electro Static Analyzer Reflight (iMESA-R), from the US Air Force Academy, was built to collect space weather data to aid mitigation for RF communication and navigation signals.
- The Rad Hard Electronic Memory Experiment (RHEME) was developed by the Air Force Research Laboratory (AFRL) to test new radiation hardened memory solutions.
- The High Bandwidth Anti-Jam Low Probability of Intercept/Low Probability of Detection (LPI/LPD) Optical Network (HALO-Net) payload from the Space and Naval Warfare Systems Command was designed to demonstrate components of a new satellite laser communications system.
The satellite was launched on Spaceflight Industry's SSO-A multi-satellite launch on a Falcon-9 v1.2 (Block 5) rocket.
