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.
