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. 

The company 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.  

Company History

Spire Global was originally known as NanoSatisfi, Inc. that was established in 2012 in San Francisco, USA. Three International Space University Graduates, Peter Platzer, Jeroen Cappaert and Joel Spark started the ArduSat projectto ‘democratize access to space’. ArduSat was partly financed thru the public crowdfunding platfom KickStarter and raised 100,000 USD.

In 2013 Spire partnered with Lemnos Labs in order to raise additional capital required for the manufacturing of the ArduSat-1 and ArduSat-2 (1U CubeSat) satellites. In February 2013 funds of 1.5million USD were raised by Investment and space companies such as Shasta Ventures, Lemnos Labs, E-merge, Grishin Robotics, and Beamonte Investments.

In November 2013 both ArduSat-1 and ArduSat-X were successfully released from the Japanese Kibō Experiment Module of the ISS and quickly started transmitting data to Spire servers. 

Following this experimentation, Spire engineers opted to focus on 3U nanosatellites to start porting more complex payloads In June 2014 the first iteration of its standard satellite format, LEMUR-1, was launched with the Dnepr rocket, a modified Ukrainian missile known as the R-36M operated by ICS Kosmotras. 

In July 2014 Spire Global announced another 25 million USD of funding that was led by Venture Capitalists. In August 2014 the company announced that ArduSat would be spun-off of the company and would focus exclusively on educational technology in partnership with U.S. high schools. Also, in 2014, Spire opened its Singapore office and started steadily increasing its network of ground stations.

LEMUR Satellite Constellation

LEMUR-2 is the initial constellation of low-Earth orbiting satellites built by Spire. These satellites carry two payloads for meteorology (SENSE payload) and ship AIS traffic tracking (STRATOS payload). Later satellites, beginning with the 78th satellite launched, carry also the AirSafe ASD-B payload to track airplanes.

The LEMUR-2 satellites are launched in small batches as secondary payloads on various rocket boosters executed by reputed launch providers:

• On September 28^th 2015 the first four more LEMUR-2 satellites were launched as a piggy-back on the AstroSat mission on a PSLV launcher, operated by ISRO from India. 
• Spire’s second batch of LEMUR-2 satellites was launched on March 22^nd 2016 with the Cygnus CRS-6 cargo ship atop an Atlas V booster operated by ULA to be launched to the ISS. The mission was flown for Orbital ATK (Lockheed Martin) under NASA’s Commercial Resupply Services contract. With a payload of more than 16,000 pounds it was the heaviest payload to date launched on an Atlas V.
• Four of the satellites were deployed from the ISS airlock, five of them directly from the NanoRacks NRCSD-E deployer on the Cygnus vehicle. Deployment of the ISS satellites began on May 18^th 2016.

In November 2021 the company signed an agreement with CubeSat satellite launch deployer NanoRacks for the deployment of two 0.3U CubeSat satellites in what was to become “the first U.S. Commercial Satellite Deployment from the International Space Station (ISS). The satellite, named FEES2 (Flexible Experimental Embedded Satellite-2), was developed by the Italian company GP Advanced Projects and is approximately the thickness of a cherry. It will be one of the smallest trackable objects deployed directly from ISS.

In late November 2021, Spire acquired exactEarth, Ltd, a leading provider of global maritime vessel data for ship tracking and maritime situational awareness solutions. After the merger, exactEarth will be fully owned by Spire and will become a subsidiary operating from Cambridge, Ontario, Canada.

On June 28^th, 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.

In February 2025 the Canadian Space Agency awarded Spire Global Canada and OroraTech a 50 million USD contract to design and develop a dedicated satellite constellation to monitor wildfires in Canada. This project is part of the WildFireSat mission to enhance wildfire detection and response. Spire will partner with OroraTech to develop the payloads for the constellation, which is scheduled for launch in 2029. It will operate for at least five years under the management of the Canadian Space Agency.
