qbcan compact, Open Cosmos’ latest CanSat educational kit has been specifically developed to help students and enthusiasts learn how to design and operate a satellite.

qbcan offers an exciting way for users to learn engineering skills including coding, electronics, telecommunications, space systems…

It features all standard satellite systems including power, sensors and communication systems all contained within the volume of a soft drink can.

Open Cosmos’ qbcan compact has been designed with plug-to-play features as well as all the required capabilities of a standard CanSat.

These capabilities include radio communications, temperature and atmospheric pressure sensors as well as a computing platform with a wide range of interfaces, all integrated within a 6cm diameter PCB disk.

qbcan is designed to have both CanSat or ground station functionalities, meaning two of them can be used in a mission with full compatibility between them.
