The following webinars provide information about MagQuest Phases 1 and 2.
- MagQuest Phase 2 Program Management Webinar. In this webinar recording, Dr. James Cutler from the Department of Aerospace Engineering at the University of Michigan discussed how solvers might approach the Concept of Operations (ConOps) for their Phase 2 submissions, as well as program management considerations for risk assessment, schedule, budget, and team structure.
- MagQuest Phase 2 Technical Webinar. In this webinar recording, MagQuest judge Dr. Arnaud Chulliat (University of Colorado Boulder and NOAA/NCEI) and magnetometer expert Dr. Mark Moldwin (University of Michigan) presented a deep dive on magnetometer technologies, explored potential sources of data interference, and discussed examples highlighting best practices.
- MagQuest Phase 2 Informational Webinar. This webinar recording covers key differences between Phase 1 and Phase 2, including format, fidelity, and the new opportunity to connect with the MagQuest solver community. The session concludes with a live Q&A.
- MagQuest Phase 1 Informational Webinar. This webinar recording provides an in-depth overview of the challenge, shares considerations and guidelines for submissions, and concludes with a live Q&A, summarized here.

- NGA overview. NGA. The official website for the National Geospatial-Intelligence Agency.
- World Magnetic Model technical overview. NOAA / NCEI. Provides a detailed overview of geomagnetic forces and important considerations for creating the WMM.
- World Magnetic Model video overview. COLABS Colorado. Provides an approachable overview of how the WMM is created and what applications it informs.
- World Magnetic Model summary. British Geological Survey (BGS). Provides an approachable summary of the World Magnetic Model purpose and development process.
- World Magnetic Model applications. NOAA / NCEI. Describes common applications of the World Magnetic Model, including uses for navigation and within consumer electronics.
- 2015 World Magnetic Model Report. NOAA / BGS. Contains a complete report of the World Magnetic Model.
- World Magnetic Model update. Nature International Journal of Science. Describes the erratic motion of the north magnetic pole that necessitated an out-of-cycle update to the WMM.
- World Magnetic Model Mil-Spec. NGA. Details the specifications required for the World Magnetic Model.
The following resources detail technologies that are used to collect data for the World Magnetic Model or may be potential alternatives. A resource with guidance for on technology readiness definitions is also included.
- Technology Readiness Assessment (TRA) Guidance. U.S. Department of Defense. Provides descriptions for varying technology readiness levels (TRLs) including TRL 5 and 6, which are both referenced throughout the MagQuest submission form and selection criteria.
- ESA Swarm mission overview. ESA. Provides an overview of the Swarm mission, including primary objectives and technology.
- ESA Swarm mission. BGS. Provides a background on the Swarm missionthat collects data for the WMM today, including an overview of technologyand instrumentation.
- Magnetic field: learning more with Swarm video. ESA. Provides a visual overview of the ESA Swarm mission history and objectives.
- INTERMAGNET ground observatories. Intermagnet. Provides an overview of theglobal ground observatory network structure and objectives.
Potential solution areas
The following examples demonstrate a range of solutions that could be submitted. Note that this list is illustrative, and is not a comprehensive list of all potential solution areas
- Spaceborne. A solution that integrates one or more small or large satellites, or proposes adding instrumentation to an unrelated mission as a hosted payload.
- Terrestrial. A solution that indicates how the existing ground observatories or mobile technology could be leveraged.
- Aerial. A solution that proposes drones, balloons, or other aerial technology.
- Data analysis. A solution that proposes how available data sources could be utilized through new advancement in data modeling and processing techniques. (Reminder: the Challenge does not ask solvers for alternate methods of creating the WMM; it asks solvers to identify new data sources to inform the current WMM production.)
Target performance metrics
MagQuest seeks solutions that will capture data sufficient to produce the World Magnetic Model. The performance specifications below represent thresholds for solutions to consider.
In Phase 2, these specifications were intended to provide guidance and for solvers to consider how they could demonstrate performance in a potential Phase 3. These target performance metrics are an updated version of the information provided in Phase 1.
|Measurement location||Sufficient number of homogeneously distributed points around Earth for a model complete to degree and order 12 along with its secular variation meeting the WMM performance specification
|Measurement positioning and timing accuracy||Preferably provided by dual frequency GPS receiver and with specifications similar to previous satellite mission performance (e.g., Ørsted, Swarm)|
In geographic frame, after accounting for orientation/attitude error, crustal biases, spacecraft/aircraft fields, biases due to temperature effects, mechanical noise, and any other systematic noise source
In geographic frame, see also preamble of “Measurement accuracy” for details
