Our next generation AAC SpaceQuest STS-300 AIS Receiver is a 6-Channel on board processing (OBP) AIS payload capable of receiving more than 1 million AIS messages per day.
The STS-300 is AAC SpaceQuest’s 4th generation design leveraging the technical and operational insights gained from developing and flying AIS receivers for the past 7 years to offer a truly reliable high-performance solution.
The STS-300 covers all AIS channels in the maritime band, from 156 to 162 MHz. This high performing payload, derived from the flight proven STS-200 is ideal for CubeSat and MicroSat missions with size, weight, and power constraints.
This versatile and high-quality AlS Receiver is not only compatible with major AIS-ready navigation systems, but it also comes as one easy-to-install package.
Reliability
AAC SpaceQuest have flown the AIS receiver’s product family for the past 7 years and as such have leveraged the technical and operational insights gained to offer a truly reliable high-performance solution.
Performance
