D5 Space vs Reflex Test App

The fifth space APP communicates with the STbox satellite terminal through Bluetooth to realize the satellite call function of the mobile phone. Based on the satellite call function APP, the core function of SOS is designed to make emergency calls with one click and cooperate with our emergency management platform for emergency treatment. At the same time, it also provides basic functions such as making satellite phone calls, sending satellite SMS messages and real-time positioning information.
