Gaintron APP is a supporting mobile application for satellite communication developed by Shanghai Jeatron Technology Co., Ltd. It is deeply adapted to the company’s self‑owned satellite communication hardware devices. Powered by global satellite communication networks, the app works entirely free from terrestrial base stations. It runs stably during power and network outages triggered by floods, earthquakes and other disasters, as well as in signal‑dead remote areas including mountain wilderness, open oceans and gobi deserts. The application comes with three core functions: satellite voice calls, two‑way satellite short messages, and one‑tap SOS alert. Accurate location coordinates will be uploaded synchronously once an SOS alert is activated. As an essential part of Jeatron’s satellite emergency communication system, the app enables well‑coordinated hardware‑software interaction. Oriented to emergency rescue, field engineering survey, outdoor operations and offshore inspection scenarios, it establishes an all‑weather uninterrupted emergency communication link to comprehensively protect field personnel’s personal safety and guarantee smooth on‑site command‑and‑dispatch communications.
