Date of launch: 23 June 2017

During this ISILaunch19 launch campaign, ISISpace engineers were responsible for the integration of the 20 CubeSats onto the PSLV launch vehicle, using satellite deployer systems and sequencing electronics developed in Delft. The ISL team took care of the final integration of all hardware on the launch vehicle at the launch site in India, resulting in the successful launch.

Among the 23 satellites, there were 8 CubeSats that will complement and complete the QB50 constellation for upper atmospheric research ( This project, sponsored by the European Commision’s FP7 is managed by the Von Karmann Institute from Belgium and ISISpace has been one of the consortium partners of QB50 since the start. The CubeSats launched by ISISpace into polar orbit will work together with the CubeSats deployed from the International Space Station in May.
The ISILaunch19 manifest also included several payloads that were initially scheduled for a launch on a Falcon 9 mission through Spaceflight’s Sherpa mission, a launch that was significantly delayed due to various factors. ISL and Spaceflight have jointly worked on re-manifesting these payloads to this PSLV launch to make sure our customer’s satellites were launched earlier. Such a re-manifesting of payloads clearly shows the added value of the ISILaunch Services of ISISpace to serve the CubeSat community, offering access-to-space flexibility towards customers of launch services by operating across multiple launch vehicles and missions in parallel.
