UAV Border Inspection in Xinjiang China

September 9, 2017

 

Background: From Jun to Aug 2017, the borer situation of Tibet and Xinjiang are very tense. In May we attended a bidding for Xinjiang border inspection project and win the bid. Because the project is for Army. So we are not allowed to public any information about that project. Before the attendingt the bidding, we took a testing in Hebei Province China.

 

 

Problem:

1. The Video wireless transmitting distance need to upto be 50km
2. 50km is too long for fly control system to control the UAV.

 

Solution: On board using ST50HPT with 5db omni antenna. On ground station with 12db omni antenna
Fly control system using the ST50HPT's 2.4Ghz data transmitting channle to do the UAV control. On board, the ST50HPT TX connect with HDMI camera and control system by TTL S1 convert to RS232 port. On ground station, the ST50HPT connect with fly control system by S1 interface convert to RS232 port.
