Laboratory tests explore how commercially available receivers respond to meaconing and spoofing, with the goal of developing useful test methodologies and metrics to assess receiver robustness and resilience to real-world spoofing threats.
The fifth GPS III satellite rising in 2021 will ride aboard a previously used Falcon 9 first-stage booster, in a first for a National Security Space Launch mission. Space Exploration Technologies Corporation (SpaceX) has contracted with the U.S. Space Force’s Space and Missile Systems Center Launch Enterprise to reuse the booster rockets.

A satellite launching in November will use GNSS – Radio Occultation (GNSS-RO) to collect highly accurate global temperature and humidity information as an aid to more accurate and more advanced weather forecasting. Developed by NASA’s Jet Propulsion Laboratory (JPL), the spacecraft’s GNSS-RO instrument tracks GNSS satellite signals to measure the physical properties of Earth’s atmosphere.
