Introduction
The GPS Smart Receiver is an ultra low power GPS receiver based on the proven technology found in this 16-Channel GPS receivers and NEMERIX chipset solution. The positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the device. With its ultra low power consumption, the smart receiver tracks up to 16 satellites at a time, re-acquires satellite signals in 1 second (average) and updates position data every second.
