Global Positioning System (GPS)
Global Navigation Satellite System (GNSS)
Receiver and Positioning Engine Solution
Sony Semiconductor Solutions Global Positioning System (GPS) / Global Navigation Satellite System (GNSS) receiver and processor chips use high frequency analog circuits and digital signal processing circuits with proprietary designs to deliver accurate positioning with the lowest power consumption level in the industry. This low power consumption performance helps extend the operating times of the IoT (Internet-of-Things) and wearable products that use GPS / GNSS.
As location-aware IoT devices intend to spread accross almost every application, IoT devices are going to require different Global Navigation Satellite System receiver design requirements. To deliver on IoT opportunities, system architects and designers need to look carefully at every aspects of system design and architecture to be able to enable the full potential of the IoT era. IoT devices are equipped with different connectivity sensors that can provide a reliable integrated location awareness solution. IoT devices are mainly relying on the GNSS chip to deliver a service when no other RF signal is available. Hence, the GNSS chip is expected to maintain a robust and relaible performance even in harsh environments. The harsh environments include multipath environment, NLOS (Non-Line of Sighht) GNSS signal reception, weak GNSS signal power reception, superimposed motion (e.g. arm swing, floating platfor fluctuation, etc...), operation under freezing temperature, and interference.
