1.1 Introduction
GPS-622F
The GPS-622F a highly integrated smart GPS module with a ceramic GPS patch antenna. The
antenna is connected to the module via an LNA. The module is with 54 channel acquisition engine
and 14 channel track engine, which be capable of receiving signals from up to 68 GPS satellites and
transferring them into the precise position and timing information that can be read over UART port.
Small size and high-end GPS functionality are at low power consumption, the LVTTL-level signal
interface is provided on the interface connector, supply voltage of 3V~5.5V is supported.
The compact 22mm x 22mm form factor allows it to be used in many applications.
The smart GPS antenna module is available as an off-the-shelf component, 100% tested. The smart
GPS antenna module can be offered for OEM applications with the versatile adaptation in form and
connection. Additionally, the antenna can be tuned to the final systems’ circumstances.
