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

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.
