LEO Satellite System for Remote Sensing

Low Earth Orbit(LEO) satellite system with remote sensing generally refers to a satellite system composed of multiple satellites that can perform real-time information processing. The low-orbiting satellite (1000~5000km from the ground) takes a short time around the earth, usually 2~4 hours. With the characteristics of easy to obtain high-resolution images of targets, low-orbit satellites are generally small satellites used to track and transmit real-time information which mainly used for military target detection.

The LEO satellite system is considered to be the newest and most promising satellite mobile communication system and has a low launch cost. LEO satellite system is used for remote sensing The LEO satellite system adopts X-band X/Y type pedestal ground station with light weight and high speed. X-band is most popular for tracking LEO satellite system.

Features of LEO satellite system:

On the one hand, the low orbital makes the transmission delay short and the path loss small. A constellation multiple satellites can achieve true global coverage, and frequency reuse is more efficient;
On the other hand, technologies such as cellular communication, multiple access, spot beam, and frequency reuse also provide technical support for low-orbit satellite mobile communications.

Antesky 3.7m X-band antenna with X/Y pedestal and 5.2m X-band remote sensing antenna system as well as 4.5m S/X band antenna are used for tracking LEO satellite system.
