The HOLUX GR-231 Smart wire-less Bluetooth GPS Receiver is a total solution GPS
receiver with Bluetooth, UART interface and built-in rechargeable battery for
high sensitivity to tracking signal. GR-231 design is based on SiRF Star IIe/LP
low power Architecture. GR-231 is a dual-function GPS receiver. 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-231 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-231 tracks up to 12 satellites at a time,
re-acquires satellite signals in 100 ms and updates position data every second.
Main functions
GR-231 provides a series of functions. It is well suited to system integration
and
users who use PDA, Notebook PC with Bluetooth device.
