Quick Summary

The National Geospatial-Intelligence Agency (NGA), under the Department of Defense, has issued a Presolicitation for Mathematical Gravity Modeling Advancement (MaGMA). This effort seeks to develop more realistic planetary models, improve analytic continuation code, and explore new computational approaches for spherical harmonic expansion (SHE) model coefficients. The primary place of performance is Saint Louis, MO. This is a Presolicitation notice, indicating an upcoming opportunity. Responses are due by April 30, 2026.

Scope of Work

  • Develop realistic planetary models with spatial and radial density variations, incorporating finer resolution in regions of interest. Models will include Earth, fictitious planets, and other bodies (e.g., Moon, Bennu).
  • Implement and improve analytic continuation code, integrating NGA-provided code into the main NGSC and developing new methods, with an evaluation for parallel computation applicability.
  • Develop and explore theoretical bases for new computational approaches to estimate SHE model coefficients, including "out-of-core" inverse techniques like stochastic gradient descent (SGD).
  • Conduct reviews of potential new research avenues aligned with these topics, collaborating with NGA SMEs and the Principal Investigator.
