Spire Global Launches Quantum Magnetometer Satellite for MagQuest Challenge

Event summary

  • Spire Global launched a satellite aboard SpaceX’s Transporter 16 mission on April 01, 2026, as part of the MagQuest Challenge.
  • The satellite integrates Spire's infrastructure with SBQuantum's diamond quantum magnetometer to measure Earth’s magnetic field from low Earth orbit (LEO).
  • MagQuest is a multi-phase challenge by NGA to improve geomagnetic data collection for the World Magnetic Model (WMM), used in navigation and military systems.
  • Spire and SBQuantum will provide data to NOAA and NASA, with potential for additional funding beyond the three-year challenge period.

The big picture

Spire Global’s participation in the MagQuest Challenge highlights the growing role of commercial satellite infrastructure in advancing geospatial intelligence. The integration of quantum technology with space-based data collection could set a new standard for measuring Earth’s magnetic field, potentially influencing future NGA acquisition strategies and enhancing navigation systems globally.
