Sony Releases GNSS Receiver LSIs for IoT and Wearable Devices – Inside GNSS
Increasing use of IoT and wearable devices that utilize location information has produced growing demand for GNSS receiver LSIs. Precise positioning and reliable communications must be ensured to maintain proper operation of IoT and wearable devices, which are being used even in difficult communication environments and unstable conditions, such as multipath propagation situations caused by reflection off the ground or nearby buildings or the effects of the swinging of the arms when attached to a person’s wrist. Additionally, device size constraints necessitate a compact battery, whereas satellite signal reception and positioning when using GNSS functionality typically consumes a lot of power, resulting in poor battery life.
