Decades of experience

The ground segment is a vital partner to any space mission. It lets you operate the spacecraft, receive and process the data it generates and deliver the data and/or services to end-users.

We have nearly 30 years’ heritage in mission operations and ground system engineering for a wide variety of customers and mission types including Earth observation, communications, scientific, navigation and space exploration. We specialise in supporting both New Space and established space companies to set up their operations infrastructure and/or to introduce new ground segment technologies to their environment.

Astroscale ELSA-d mission support

We were commissioned by Astroscale to develop the mission preparation, mission control and automation systems for its first mission: End-of-Life Service by Astroscale demonstrator (ELSA-d). This was launched in March 2021.

Our team adapted and configured existing, proven ground segment technologies to support the mission. These can be reused at low cost for future ELSA missions.
