The main goal of GU-168 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 (GU-168) 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. In the specification of GU-168 at the next page, it is noticeable that in addition to excellent start-up times and position accuracy, the updated rate can be up to 5 Hz and the sensitivity of -160dbm.
