Positioning Reference Signals (PRS) over Satellite

Standardized 3GPP downlink reference signals allowing smartphones to calculate hyperbolic time difference fixes across passing satellites.

3GPP PRS Architecture

Standardized 3GPP downlink reference signals allowing smartphones to calculate hyperbolic time difference fixes across passing satellites.

Orbital deployments adhere strictly to 3GPP NTN specifications, CCSDS packet telemetry, and radiation-hardened spaceborne payload standards.

Sub-millisecond synchronization across high-velocity Low Earth Orbit constellations.
Radiation-hardened spaceborne transceivers supporting 3GPP NR-NTN Release 17/18/19.
Seamless handover management bridging non-terrestrial orbits with terrestrial cellular cores.
