    The device key target is to allow GNSS positioning for asset management applications where infrequent position updates are required. The Adrastea-I GNSS shares the RF Rx path with the LTE modem and, therefore, cannot operate in parallel with LTE data transfer. Hence this GNSS is not suitable for products that inherently require this co-existence, LTE connection and GNSS tracking.
