High-sensitivity mini GPS receiver modules of low cost
The main goal of GM-1315LA is to be used as a part of integrated system, which can be a simple PVT (Position-Velocity-Time) system, for instance, G-mouse, PND (Personal Navigation Device), or complex wireless systems, such as a system with GSM function, a system with Bluetooth function, and a system with GPRS function. The module (GM-1315LA) can be the best candidate for users’ systems as the users’ systems need the careful consideration on the performance, sensitivity, power consumption, and/or size of the module.
  • Active antenna on board helps the system integrators to do the design-in easily.
  • High sensitive GPS Locator and GPS antenna.
  • MMCX connector design to support external GPS antenna.
  • The perfect match is most suitable for any mobile devices, such as PND, GPS PDA, personal tracker and any portable devices, which need GPS features.
