Ground contact to the aircraft during mission is a vital stepin safe operation. For the inmission support OptaMission provides a tactical data link on various frequency bands and via SatCom. The ground station keeps in touch with all the operating aircraft within the radio circuit. With OptaMission's request function the position of the mission aircraft will be identified and tracked. OptaMission provides frequency lists for radios both on-board the aircraft and on the ground. It enables plain and encrypted links for both voice and data. OptaMission provides mechanisms for updating critical information during the mission such as new threats, NOTAMs, or obstacles. A further application of the datalink is to upload optimised route data for safely rerouting the aircraft according to the new information.
