The first satellite, dubbed NORsat-1 carries a state-of-the-art Automatic Identification System (AIS) receiver to acquire messages from maritime vessels, a set of Langmuir probes to study space plasma characteristics, and a Compact Lightweight Absolute Radiometer (CLARA) to measure total solar irradiation and variations over time. The payloads were provided by Kongsberg Seatex, the University of Oslo and the Physikalisch-Meterologisches Observatorium Davos World Radiation Center.
The satellite is approximately 15 kilograms with main body dimensions of 20x30x40cm. NORsat-1 utilizes SFL’s Next-generation Earth Monitoring and Observation (NEMO) platform, and will serve the Norwegian Coastal Authority in monitoring maritime traffic while also performing ground breaking science.
The second satellite, NORsat-2 also carries an AIS receiver, but in addition has a VHF Data Exchange (VDE) payload that will enable higher bandwidth two-way communication with ships. Both payloads were provided by Kongsberg Seatex. NORsat-2 will be the first satellite to provide VDE services to Norway. Adding VDE enables increased messaging capacity, better reliability of message delivery, and increased range of ship-to-shore and ship-to-ship communication beyond direct line of sight.
SFL’s NEMO platform was used for NORsat-2, and the satellite was integrated in Toronto along with NORsat-1. The relatively large deployable Yagi antenna for the VDE payload was developed by SFL in collaboration with the University of Toronto’s Electromagnetics Group.
About Space Flight Laboratory (SFL)
SFL builds big performance into smaller, lower cost satellites. Small satellites built by SFL consistently push the performance envelope and disrupt the traditional cost paradigm. Satellites are built with advanced power systems, stringent attitude control and high-volume data capacity that are striking relative to the budget. SFL arranges launches globally and maintains a mission control center accessing ground stations worldwide. The pioneering and barrier breaking work of SFL is a key enabler to tomorrow’s cost aggressive satellite constellations. (www.utias-sfl.net)
