Satellite constellations _ What are the satellite constellations?

Overview of satellite constellations

Satellite constellation is a collection of satellites launched into orbit that can work normally. It is usually a satellite network composed of some satellite rings arranged in a certain way.

Use:

Satellite constellation can be used in satellite navigation and positioning system to provide real-time speed, attitude and time information of the carrier. Satellite constellations can be used for global communication, playing the role of a transit station and transmitting communication information. Satellite constellations can also be used for global environmental monitoring, and global environmental conditions can be monitored by remote sensing global surface information.

Common system

With the development of miniaturization, batch and constellation of commercial satellites, the number of commercial satellites that need to be managed in orbit will increase sharply. In view of the unique operation mode of commercial satellites, in order to improve the efficiency of on-orbit measurement, control and management of commercial satellites, kering has studied a satellite constellation management system suitable for on-orbit operation of commercial satellites, which provides technical support for the overall operation and management of satellite constellations and ensures the normal completion of satellite constellation tasks.

The satellite constellation management system can realize the integrated management of on-orbit measurement and control, commercial satellite operation control, automatic monitoring and management, unattended operation, automatic task assignment and satellite tracking, complete satellite state monitoring, automatic receiving and sending, automatic processing and automatic distribution of business data, and meet the simultaneous tracking service of multiple low-orbit commercial satellites.

Support multi-constellation, multi-type satellite measurement and control, operation control, data transmission and other services, and realize various functions such as satellite overhead prediction, task assignment, remote control, telemetry, data downlink, data uplink, satellite orbit simulation, visual panel, video, ground station management, user management, log recording and so on.

● Support the dynamic display of ground beams and inter-satellite links according to constellations, and support the switching display of orbital inertial system/ground fixed system.

● Support information display functions such as tracking plan, satellite status, beam information, data flow and log.

● Support constellation measurement and control, formation and scheduling algorithm research, and support large-scale constellation scene simulation and state monitoring.
