1. Overview
(Fig.1)
The
HOLUX
GR-230 Smart wire-less Bluetooth GPS Receiver (Fig. 1) is a total
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.
This positioning application meets strict needs such as car navigation, mapping,
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.
