NRL Launches Orbital GNSS Environment Sensor Aboard STPSat-7 - Inside GNSS - Global Navigation Satellite Systems Engineering, Policy, and Design
- NRL launched three experimental payloads on STPSat-7, including GOSAS to study the orbital GNSS environment.
- GOSAS provides dual GPS receivers to monitor space weather effects on GNSS signals from orbit.
- GOSAS follows the GROUP-C mission, which detected GPS ground interference from orbit on ISS.
- STPSat-7 launched from Vandenberg Space Force Base with a Minotaur IV rocket.
- LARADO and GARI-1C accompany GOSAS to advance debris detection and gamma-ray sensor tech.
- Space Test Program enables flight opportunities for research with potential military utility.
- Experts say space weather understanding is critical for GPS accuracy and military communications.
- GOSAS aims to formalize orbital GNSS environment characterization as a dedicated mission objective.
- The mission aligns with growing counterspace awareness as GPS jamming affects LEO satellites.
