Space-Based PNT Testing and Simulation

Satellite in space

Assure PNT for Every Space Mission

Space missions depend on precise positioning, navigation, and timing (PNT) — from low Earth orbit (LEO) constellation deployment to lunar exploration. Testing PNT systems in realistic space environments is essential to mission success. Keysight’s global navigation satellite system (GNSS) and PNT simulation solutions help recreate orbital dynamics, signal conditions, and interference scenarios — so space-based PNT systems perform as expected in orbit.
