Feature(may vary by option.)

●This usb gps works with Windows, Linux, Raspberry PI and Google Earth, not for IOS Android
●The vk-172 gps is NOT plug and play for most device. You need to install driver before make it work. Raspberry Pi and linux no need driver.
●VK-172 automatically adapt the baud rate, The baud rate has any data output.
●The default output is GPS protocol data,you can modify the PS/GLONASS protocol data by testing software or serial commands.
●VK-172 built-in high-gain LNA, dual-channel LDO, large area radiation GPS optional baud rate 4800, 9600, 19200, 38400, 5700, 115200, etc.
