ELNS prototype in flight testing
CTSi and its partner L3 Technologies have completed flight-testing of the Enhanced Link Navigation System (ELNS) designed for use in highly contested and GPS-denied environments, CTSi announced on 10 July.
During the flight testing, carried out near Patuxent River, Maryland, the newly developed integrated communication and navigation system provided area navigation to replace GPS at ranges in excess of 50 nautical miles all the way through landing during 15 flights, which included 152 approaches.
The ELNS prototype has been developed under a US Navy $8.7 million contract.
ELNS uses L3 Technologies’ waveforms that defeat adversary strategies to detect and disrupt allied signals, using waveforms that are essential in communications-denied and GPS-denied environments. It can be mounted on all groups of UAS, from those needing high integrity such as the MQ-25, to small UAS.
