CNPC Terrestrial Command and Control Radio
The SkyLink Command and Non-Payload Control (CNPC) Data Link is a Command and Control (C2) frequency modulated radio intended for point-to-point or networked UAS operations for Beyond Visual Line of Sight Operations.
Unique to UAS C2 radios, SkyLink includes both antenna diversity and radio diversity. Each SkyLink unit includes dual radios which enable “make before break (MBB)” connectivity when transitioning from one ground station to the next. MBB ensures a solid handoff between one operator using one ground station to another operator using a second “target” ground station by ensuring the target ground station has a solid connection before releasing control from the initial operator. For many customers, this helps to close the safety case during a high-risk portion of an operation.
SkyLink is designed and developed for certification using Design Assurance Level C (DAL C) as designated in RTCA DO-178C and DO-254. SkyLink is currently operating under experimental licenses on L-Band as a Multiple Input, Single Output (MISO) dual radio solution.
