Help: COVE API User's Guide: Custom Missions

The Custom Missions feature allows users to create notional or proposed missions, and request a list of custom missions a user has already created. Custom Missions may be used in Acquisition Forecaster, Revisits Calculator, and Coincident Calculator to submit tasks.

Custom Missions throttle limits:
  • GET: 120 requests per hour

Create a custom mission

The endpoint will allow users to create one custom mission with multiple custom instruments. Custom missions may be created from existing missions or with new mission details. Custom instruments may be created from an existing mission’s instrument-mode or using new instrument details. Custom instruments may be added to an existing custom instrument. Refer to the COVE UI User's Guide for additional details on creating custom missions.

Input parameters to create a Custom Mission:
Parameter Name Data Type Required Description
custom_mission Yes Refer to Special Data Types for more information on ExistingMissionFilter, CircularOrbitFilter, SunSynchronousOrbitFilter, or AdvancedOrbitFilter.
custom_instruments CustomInstrumentsFilter [ ] Yes Refer to Special Data Types for more information on CustomInstrumentsFilter.
