Tracking Technology types
Personal GPS Tracking handsets are available in two types, with either cellular or satellite messaging. Check below to find the best type for your activity:
DQ30 Cellular/GPRS For general purpose tracking of journeys & sporting activities in areas where there is mobile network coverage, the DQ30 uses a SIM card to transmit its location via GPRS messaging. There is always a data connection with the mobile network - important if you're using your tracker for SOS messaging. The tracking intervals (how often the device logs its position) are optimised to give the best battery life for each application. Costs - GPRS messaging is cheaper than satellite (see DQ30 susbscription cost here), particularly for transmitting large amounts of telemetry information, or very short reporting intervals. Coverage - As mobile coverage generally extends some distance off-shore, GPRS handsets can be used for watersports activities in popular areas. The DQ30 has an exceptional battery life, so can also be used for temporary tracking in boats, vehicles or even Outboard motors as a movement alarm. View DQ30 details
Spot Satellite handsets also receive position co-ordinates from the GPS system, but they transmit location details using the Globalstar Simplex network, designed for low-cost asset tracking. Coverage - Spot devices work on European, US & other global land areas - wherever there is a clear view of the sky. Costs - satellite networks have higher data charges than cellular, and tracking intervals are generally longer to off-set this. The Globalstar network which provides the 'Spot' messaging is one-way, so the handsets only transmit their location & do not receive messages. Spot handsets use a single login to Google Maps, or are available for group or fleet tracking with Duotraq's web portal with geofencing & reporting features.
