SBT-268 Bluetooth GPS Receiver  |
|
|
|
|
|
The SBT-268 wireless Bluetooth GPS receiver incorporates a state-of-the-art wireless Bluetooth radio module and built-in rechargeable battery, low consumption SiRF star III chipset in an elegant design. As a dual-function GPS receiver, it not only transmits the satellite information through PDA or Notebook with Bluetooth interface but also is a G-Mouse receiver through a data cable to deliver satellite signal to the device without Bluetooth interface. This positioning application meets strict needs such as vehicle navigation, mapping, surveying etc. With its ultra low power consumption, the receiver tracks up to 20 satellites at a time while offering fast time-to-first-fix, re-acquires satellite signals in 100 ms and updates position data every second. Trickle-power allows the units operate a fraction of the time and Push-to-fix permits users to have a quick position fix even though the receiver usually stays off.
