Key highlights

The Oxford Space Systems deployable 3-Element Yagi antenna provides high RF performance for CubeSat maritime VDES/AIS applications. From only a 1U stowed package, it deploys in a single step using strain energy. The antenna is flight-proven (TRL 9), enabling the next generation of Automatic Identification System (AIS) and VHF Data Exchange System (VDES) services for vessel tracking and other maritime navigational and data exchange purposes.
