Spire Global satellite operator is operating the LEMUR LEO CubeSat satellite constellation for earth observation.

Spire Global is a space-to-cloud CubeSat satellite operator that is specialized in the tracking of unique data sets from the Earth powered by a large constellation of small LEO satellites (nano-satellites), the Low Earth Multi-Use Receiver (LEMUR) CubeSat platform. Spire analyzes data from the tracking of maritime, aviation and weather patterns.

Spire Global satellite operator operates a fleet of more than 110 CubeSats, the second largest commercial constellation by number of satellites and the largest by number of sensors. The satellites are integrally designed and built by Spire. It has launched more than 140 satellites to orbit since the creation of the company in 2012. Spire Global is headquartered in San Francisco, USA and has offices in Boulder, Washington in the USA, Glasgow in the UK, Luxembourg and Singapore.

On June 28th, 2023 the company announced an extended partnership with satellite operator OroraTech from Germany. The objective of this collaboration is to jointly develop, launch, and operate a constellation of eight satellites exclusively designed for global temperature monitoring. This groundbreaking initiative aims to establish one of the earliest and most extensive constellations dedicated to the tracking and monitoring of wildfires worldwide. Once deployed and fully operational, this constellation will play a pivotal role in enhancing our ability to observe and respond to wildfires on a global scale.
