5.2M X-band Remote Sensing Antenna System

1. Main Function

Remote sensing satellite data receiving antenna system has the ability to track the target effectively, which collects, capture and track the X-band signal transmitted by satellite.

5.2M X-band Remote Sensing Antenna System

2. Technology Features

The feature of remote sensing satellite data receiving system are as follows:

• To receive and record multi-satellite data and with the ability of formation of all-weather and multiple resolutions , to achieve one station, multi-satellite.
• Track the medium and low orbit satellite to achieve the orbital height of more than 250km full airspace without blind area tracking with the adoption of light X-Y antenna mount.
• High system integration; friendly man-machine interface; easy operation and maintenance, automatic tracking and other capture capabilities with program.
• Strong self-testing, condition monitoring and alarming
• Lightning-Proof Protection
• Perfect Security Protection
