The GPS-U1 is a highly sensitive, low power and ultra-slim GPS module. It can support up to 66 channels of satellite searching. Even at high speed vehicle movement it has a special function to provide maximum update rate of 10Hz to provide the user with precise position fix and vehicle velocity. It delivers major advancements in GPS performances, accuracy, integration, power consumption and flexibility.
It is designed to be suitable for embedded system integration and simplifies the design procedure by module structure. The GPS-U1 module is the best choice for integrating GPS functionality into any embedded application.
