Berlin Space Technologies (BST) unveils satellite platform for mega constellations

September 28, 2023

On the occasion of the International Astronautical Congress, Berlin Space Technologies GmbH (BST) unveils its extended LEOS-100 platform.

LEOS-100 is aims to support demanding satellite missions with 200-500kg mass. It is based on the flight proven LEOS-50 platform with which it shares its in-house made avionics.

LEOS-100 has been in the works by BST since 2019. It has been designed for low NRE, the ability to be manufactured in <1 week per unit, high reliability, and performance.

The first EM level LEOS-100 bus system will be delivered to a customer in January 2023 and mass manufacturing will be done in our new Berlin based factory starting end of June 2023.

“With LEOS-100 we are extending the range of our flight proven satellite platforms”, explains Tom Segert, CEO of BST. “Development has been internally funded to suit a class of missions for which we see an increased demand.”

“The development for the extended LEOS-100 started with requests from our partners and followed two main questions: how can we re-use most of the avionics of our flight proven LEOS-50 platform, and how can we facilitate a build time of 1 week or less for one satellite in our factory” says Matthias Buhl CTO of BST. “Re-utilisation and optimisation instead of re-inventing the wheel allows for very fast mission implementation and it also shows in reduced cost” adds Björn Danziger COO.

“In the last 10 years BST sold more satellites (50+kg) that were designed and built in Germany to commercial customers than anybody else. The extension towards larger platforms of 200-500kg is the logical next step. With our technology, our heritage, and our factories there is no-one better placed than us to manufacture high fidelity micro and mini satellites at the most competitive prices” concludes Dr. Farid Gamgami, CSO of BST
