The main goal of EB-85A 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 (EB-85A) 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 EB-85A 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 -158dbm. The active antenna on board helps the system integrators to do the design-in easily. EB-85A is feature with high sensitive GPS receiver and GPS antenna. The perfect match is most suitable for any GPS mobile devices, such as PND, GPS PDA, personal tracker and any portable devices, which need GPS features.
