How does the Safe Sport Tracking Trackers determines their position?

All Safe Sport Tracking Trackers are equipped with a GPS Antenna as well as a GSM Module. GPS intervals can be determined in as little as 30 seconds to once in 12 hours intervals and transmitted form every 2 minutes to once in 24 hours – all settings are done on-line. If the Safe Sport Tracking Tracker goes out of a GSM area, the Safe Sport Tracking Tracker can store up to the last 2,000 GPS points acquired and as soon the Safe Sport Tracking Tracker communicates with the Vodacom GSM network, then the last GPS points will be sent to the Safe Sport Tracking Server.
