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.
Implementation & Spacecraft Integration
在轨空间部署严格遵循 3GPP NTN 规范、CCSDS 遥测标准以及抗辐射宇航级载荷系统工程指标。
- 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.
