China completes health check on BDS satellite constellation by Staff Writers Xian (XNA) Jan 26, 2022
A health check on all 52 in-orbit satellites of China's BeiDou Navigation Satellite System (BDS) has been completed, according to the Xi'an Satellite Control Center. The center said the satellites met all key indicators, meaning the constellation can provide services without issue. The evaluation was conducted without interrupting the satellites' usual navigation services, and developers and users were invited to participate in the process. In addition to the assessment, a bespoke maintenance plan was drawn up for each satellite to ensure operational efficiency. : Source: Xinhua News Agency
Providing GPS-quality timing accuracy without GPS Washington DC (SPX) Jan 21, 2022 Synchronizing time in modern warfare - down to billionths and trillionths of a second - is critical for mission success. High-tech missiles, sensors, aircraft, ships, and artillery all rely on atomic clocks on GPS satellites for nanosecond timing accuracy. A timing error of just a few billionths of a second can translate to positioning being off by a meter or more. If GPS were jammed by an adversary, time synchronization would rapidly deteriorate and threaten military operations. To address this s ... read more
