Minimize Spire

spireSpire's constellation of 60+ nanosatellites is designed, built, and operated by Spire out of Glasgow, UK and its European headquarters in Luxembourg. With a diversified launch manifest and the capacity to build up to two satellites per week, Spire's constellation continues to grow. The 28-strong ground station network provides timely data that is processed by Spire and made available through their customer API.

Spire is a data and analytics company that collects data from space to solve problems on Earth. They identify, track, and predict the movement of the world's resources and weather systems by "listening" to the planet in real-time and applying machine learning to understand what will happen in the future. They continue to launch additional satellites and add new payloads to the constellation.

Spire data familiarization phase for the Earthnet Third Party Mission programme

21 November 2018

ESA and Spire are pleased to announce the opportunity to freely access, up to March 2019, through the Third Party Mission programme, 6 different samples of global Spire satellite data.

Minimize Mission Facts and Figures

Spire's constellation is composed of Lemur nanosatellites with the majority of them officially licensed as Lemur-2 and with the name of a Spire employee.

Spire exclusively use the nanosatellite form factor. They design and build all sub-systems and integrate the spacecraft in their Glasgow facilities.  Spire is on the 18th design iteration of the satellite, aided by on-orbit operational performance and feedback, which gives unparalleled consistency and reliability of performance.

The satellites are 3 axis stabilised and do not use thrusters, have a mass of ~4.6 kg, and are in low-earth orbit (generally around 500km so that they naturally de-orbit) at various inclinations, including equatorial, sun-synchronous and inclinations in between, which gives global coverage and the ability to listen to every spot on earth more than 100 times per day. 

All of Spire's satellites have three on-board software defined radio payloads that were built in-house:

STRATOS makes use of GPS radio occultation measurements to determine temperature, pressure and humidity profiles of Earth's atmosphere for applications in operational meteorology, space weather, and climate.

SENSE is a receiver for AIS (Automatic Identification System) signal reception from ships at sea, providing worldwide tracking (identification, position, course and speed information) plus detailed vessel characteristics for maritime safety.

AIRSAFE uses an ADS-B (Automatic Dependent Surveillance-Broadcast) receiver for tracking of aircraft on a global scale.
