The Secondary Link is an advanced long-range half-duplex digital data link system that weighs just 60 grams, making it ideal for a broad range of unmanned platforms including small quadcopters and other multirotor UAS. It features simplex narrowband digital functionality and low-rate communication via UHF.
With a range of up to 250 km, the Secondary Link provides a single communication channel for commands to the unmanned vehicle and can also act as a primary link, as a redundant link for backup purposes or as a flight termination system (FTS).
The Secondary Link can also be provided as an optional part of the Commtact AMLS and IDLS-MK II systems.
The lightweight system also features a small form factor and low power consumption, providing secure and reliable performance for even the most SWaP-conscious of platforms.
