The Shenzhou-13 spacecraft safely landed on April 16th 2022, after six months aboard China’s newest orbital station in the longest crewed mission to date for the country’s space program. The spacecraft carrying three astronauts landed in northern China’s Inner Mongolia Autonomous Region, about 9 hours after departing from the core Tianhe module of Tiangong space station.

With the capsule landing site in Gobi Desert, the largest desert in Asia where cellular coverage can be patchy or even non-existent, the ground rescue and recovery team was in need of a reliable and portable communication system to coordinate and dispatch team members efficiently.
Adopting Hytera DMR communication system, the team can be divided into convenient talk groups, so only the relevant group needs to hear the call, which is a very efficient way of communicating compared with consumer mobile phone services, which are restricted to one-to-one calling, and helps to ensure smooth and discrete operations.
The system also integrates GPS function to enable team members to be monitored and located outdoors, while Bluetooth or RFID technology in the radio can be integrated with beacons and RFID tags to provide indoor location fixes. Location technology means that members can be quickly located in the case of an accident or gets into trouble if they press the emergency button or an automatic alarm is triggered.
Hytera DMR radio systems can also be integrated with fixed telephony systems, cellular networks, CCTV platforms and Internet of Things (IoT) sensor data to provide access to a wider range of data and to enable communications with people without radios or outside the DMR coverage area.
