Edinburgh / Paris, 1 September 2022. – In-orbit propulsion solutions provider ThrustMe, has delivered seven propulsion systems to Spire Global, for its LEMUR 3U satellites as the company builds upon its fully deployed constellation of over 100 satellites, ThrustMe said. This is the first time Spire will integrate and use propulsion on its LEMUR satellites.

Spire’s LEMUR (Low Earth Multi-Use Receiver) satellites will be integrated with ThrustMe’s I2T5 iodine cold gas system during their launch scheduled for Q4 2022. The propulsion system will enable for performance optimization while preparing the constellation for upcoming deorbiting regulations.

The LEMUR constellation helps track maritime, aviation, and weather activity from space. The satellites are equipped with sensors that are capable of capturing data any time of the day and in any weather conditions. The I2T5 iodine cold gas propulsion system will improve satellite manoeuvrability for phasing, collision avoidance, and end-of-life deorbiting. 

To date, ThrustMe has delivered over 20 I2T5 systems to clients worldwide. The company is currently is in the process of setting up a dedicated industrial production facility to meet commercial demand.
