Reaction Wheels
Our high-reliability, vacuum-lubricated reaction wheels are designed for picosatellites, nanosatellites and microsats. More than 240 wheels are on-orbit, performing well.
All Sinclair Interplanetary by Rocket Lab reaction wheels incorporate a built-in digital processor. They can be commanded over a serial bus to produce a desired speed, momentum or torque. They report digital telemetry concerning speed, temperature, voltage, current, and other health parameters.
1 Nms
Our largest wheel, suitable for 100 kg Earth-observation missions. There are currently 52 units on-orbit on 13 spacecraft, with the first launch in June 2016.

30 mNms
Sinclair Interplanetary’s first wheel design, and still the most popular. First launched in April 2008, there are now more than 50 units on-orbit. Many of these are onboard the University of Toronto SpaceFlight Lab's GNB series of spacecraft. They fit comfortably into a 6U to 12U cubesat.
