AI Technical Summary

Technical Problem

Existing technologies have limited receiving range and poor timeliness of ground stations, resulting in the inability to obtain the satellite-to-ground time difference in a timely manner, which may lead to inaccurate satellite orbit calculations, imaging position deviations, and loss of downlink data.

Method used

Satellite telemetry is acquired jointly by ground stations and narrowband communication terminals. After conversion, the satellite-to-ground time difference is calculated. Satellite telemetry is acquired separately by ground stations and narrowband communication terminals within different receiving ranges to establish a satellite-to-ground time difference monitoring model.

Benefits of technology

It enables precise acquisition of satellite-to-ground time difference, timely detection of anomalies, avoidance of inaccurate satellite orbit calculations, imaging position deviations, and loss of downlink data, provides a basis for anomaly handling decisions, and promotes the development of aerospace technology.
