1. OVERVIEW
Altina GBT708 Bluetooth wireless GPS Receiver is a total solution GPS receiver with
Bluetooth, UART interface and built-in rechargeable battery for high sensitivity to tracking
signal. GBT708 is a dual-function GPS receiver. Not only transmit satellite information
through the PDA or Notebook with Bluetooth interfaces but also G-Mouse GPS receiver
through a data cable.
GBT708 provide you various applications such as car navigation, mapping, surveying,
security, agriculture and so on. GBT708 communicates with other device through Bluetooth
wireless function and compatible interface of RS-232 or USB. Indeed, built-in
rechargeable Lithium-ion battery offer you a convenient use in drive and also can save
satellite information such as the status of satellite signal, the last location, date and time for
last use.
With low power consumption, the GBT708 can track up to 12 satellites at a time, and
re-acquires satellite signals in 100 ms and updates position data every second.
Trickle-Power allows the unit operates a fraction of the time and Push-to-Fix permits user to
have a quick position fix even though the receiver usually stays off.
