Onboard Systems and Electronics

The electronics system of a CubeSat plays a critical role in its operation, encompassing command and data handling, power systems, communication, and storage. Power is usually supplied by solar panels and stored in batteries for continuous operation. Advanced CubeSats employ sophisticated onboard computers, robust power management, and high-capacity storage to execute their missions effectively. Additionally, they integrate various sensors and a camera for data collection, all managed by custom-designed or commercial-off-the-shelf electronic components that maintain the CubeSat’s functionality in the harsh environment of space.

Launch and Deployment

In the era of the CubeSat revolution, the successful journey of these miniature satellites, from Earth to orbit, hinges on the orchestration of launch vehicles and deployers designed for optimal insertion into space.

Secondary Payloads

CubeSats often hitch a ride to space as secondary payloads, sharing the journey with larger primary satellite missions. This cost-effective approach utilizes deployers, like the CubeSat dispenser, which safely houses CubeSats during ascent and methodically releases them into orbit once the launch vehicle reaches a predetermined altitude.

Low Earth Orbit Insertion

For Low Earth Orbit (LEO) insertion, precision is key. Launch companies, such as Rocket Lab, have developed dedicated launch vehicles capable of placing small satellites into their target orbits with high accuracy. An example of this precision is Rocket Lab’s Electron rocket, which has successfully performed multiple CubeSat launch missions. The Electron can deploy an Airlock system, further streamlining the deployment of CubeSats into Low Earth Orbit.
