pocketgpsworld.comQstarz have released a 10Hz GPS Bluetooth GPS receiver. With a glut of GPS receivers in the marketplace and a dwindling number of devices that use them you might ask why Qstarz have released yet another BT device. Well the clue is the 10Hz update rate. What does this mean? Most normal GPS devices have a 1Hz refresh rate, that means they send out the location once a second. The Qstarz sends the location information 10 times a second.

The main benefit for the increased update rate is for users that require precise positioning, or if you are recording data at speed. This will give a much smoother curve when the data is reviewed, and will of course allow for a much finer analysis of your speed at each trackpoint. At 60MPH you travel one mile in one minute or about 88 feet per second. This means that a conventional GPS will send your position once every 88 feet (or 27 meters). The Qstarz BT-Q818XT will send your position every 9 feet (or 3 meters). You will now be able to analyse acceleration and braking much better.
