QB50 is a project consisting of 50 international double and tripe CubeSats. The CubeSats will have various scientific instruments on board to carry out atmospheric research within the lower thermosphere, between 200 - 380km altitude, which is the least explored layer of the atmosphere. There will be 3 sets of scientific equipment onboard that will be used for the research. Another purpose of the project is to study the atmospheric re-entry process.

Project information

Our project aim is to design and implement intersatellite linking between satellites. In other terms this is passing information from one satellite to another until it hits the destination satellite which is in contact with the targeted ground station.

Since a CubeSat is only 30x10x10 cm satellite there are constraints that need to be considered such as:

  • Wireless space links having high bit error rates
  • Low power budget
  • String of pearls constellation

Work Breakdown Structure

The work has been broken down so that both are able to work on the project concurrently whilst in the end being able to integrate there software.
