Detailed Product Description

Specifications:   
The HOLUX GR-239 Bluetooth GPS Receiver is a complete GPS solution featuring Bluetooth
and UART interface for high sensitivity to tracking signals. The GR-239 design
is based on SiRF Star III Single Chip Architecture and is powered directly
from a cigarette lighter, which saves the trouble of charging the device. 
The GR-239 is a dual-function GPS receiver. It not only transmit satellite information
through the PDA or Notebook with Bluetooth capability but is also a G-Mouse
GPS receiver and through a USB data cable to deliver satellite signal to the device
without Bluetooth capability.
This positioning application meets your needs with car navigation, mapping, surveying,
security, agriculture and features needed. The GR-239 connects to other device
through Bluetooth or Serial Port Profile (SPP). It supports NMEA 2.2 output
protocol, which helps to save satellite information such as the satellite signal
status, the last location, date and time of last use.
With low power consumption, the GR-239 tracks up to 20 satellites at a time, re-acquires
satellite signals in 100 ms and updates position data every second. Trickle-Power
allows the instantaneous start and Push-to-Fix permits users to obtain
a quick position fix even if the receiver is usually off.
