Geospace Dynamics Constellation (GDC) Science Planning Resources
See GDC Mission Preformulation Resources to see an archive of simulations CCMC has performed in support of GDC Mission preformulation.
NOTICE: The materials on this page are provided as resources for community planning for GDC. Any information about or requirements for a GDC solicitation will be provided by NASA Science Office for Mission Assessment.
Observing System Simulation Experiment (OSSE)
Hsu, C.-T., Matsuo, T., Kershaw, H., Dietrich, N., Smith, M., Anderson, J., et al. (2024). A community Ionosphere-Thermosphere Observing System Simulation Experiment (OSSE) tool: Geospace Dynamics Constellation example. Earth and Space Science, 11, e2024EA003684. https://doi.org/10.1029/2024EA003684
Note: CCMC can provide this type of OSSE service to other ITM mission planning as well.
