Each Ares Alpha props has an integrated GPS module. By connecting to the the Ares Alpha servers, all props will send in real-time their location on the map. Check how to integrate your props in Ares Alpha platform for more information.
GPS signal will work mostly under clear sky. Inside the buildings, the signal will be lost, or the resolution will be very low.
The initial GPS lock may take up to 10 minutes, so please be patient when starting the prop.
