China Gps mouse Manufacturer,Promotional Custom Imprinted Gps mouse,Advertising Gps mouse,discount Gps mouse supplies |
The 1920 times/HZ hardware be inside the chip to develop the receiving ,sending and searching the satellite signal.
Built-in The WASS/EGNOS demodulator.
Adopted the POLNAV lower consume chip .
It support outputted with the NMEA 0183 2.2 version
The innovation theories ,improving the ability of receiving the signal on bad position and accurate acquisition.
It can be switched easily between the Mouse and function of GPS through the Mouse switch.
Comparing the common PDA GPS ,it is advantage on the price.
Convenient ,fast set the relevant emap into the laptop,Through the USB cable to connect the computer and immediately position and navigation.
Supply the relevant district emap for free.
