solution GPS receiver with Bluetooth, UART interface and built-in rechargeable battery 

for high sensitivity to tracking signal. GR-203 design is based on SiRF Star IIe/LP low 

power Architecture.   

GR-230 is a dual-function GPS receiver. Not only transmit satellite information 

through the PDA or Notebook with Bluetooth interfaces but also is a G-Mouse GPS 

receiver through a data cable to deliver satellite signal to the device without Bluetooth 

interface.

surveying, security, agriculture and so on. Only clear view of sky and certain power 

supply are necessary to the unit. GR-230 contacts to other device through Bluetooth 

device, compatible interface of RS-232 or USB, and built-in recharge battery to save 

satellite information such as the status of satellite signal, the last location, date and time 

of last use. 

With low power consumption, the GR-230 tracks up to 12 satellites at a time, 

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.
