Six innovator teams were invited to participate in Phase 3, which will award $900,000 in cash prizes. Two of the teams — Spire Global and SBQuantum — formed a Phase 3 partnership.

Compact Spaceborne Magnetic Observatory (COSMO) CubeSat

University of Colorado Boulder

A CubeSat specifically designed and tested for magnetic cleanliness and accurate data from a compact form factor. A compact scalar-vector magnetometer designed specifically for CubeSats enables high-quality collection of magnetic field data.

Diamond powered Geomagnetic Data Collection from LEO

Spire Global and SBQuantum

A diamond quantum magnetometer system deployed on a Cube-Satellite, combining SBQuantum’s novel magnetometer technology and sensor expertise with Spire Global’s existing infrastructure for satellites, ground stations, and data processing.

Global Acquisition of Magnetic Measurements at Altitude (GAMMA)

Stellar Solutions

GAMMA leverages planned satellite missions by adding easily integrated magnetometer payloads, plus an expanded ground-based scientific magnetometer array. New miniature space sensors and payload hosting opportunities dramatically decrease costs while supporting collection of the required magnetic measurements.

Satellite Instrumentation for Geomagnetic Analysis (SIGMA)

Iota Technology

A 3U CubeSat featuring a novel deployable boom and digital magnetometers. Iota Technology is working alongside teams from Oxford Space Systems and AAC Clyde Space, combining expertise in sensor technology, deployable structures, and mission design.

Terrestrial and Seafloor Automated Magnetic Observatories

Royal Meteorological Institute of Belgium

A flexible network of automated magnetic observatories on land and the seafloor. The observatories can be deployed at almost any global location; automation delivers continuous near real-time data while decreasing staffing and support needs.
