T-type design for embedding in portable devices and receiver

The main goal of GM-12TA is 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 T-type design of GM-12TAis the best choice for embedding in portable devices and receivers like PND, mobile phone, car holder, personal locator, digital camera, and vehicle locator. It 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.
