Capturing real-time telemetry to improve estimation of maneuver performance. When a maneuver is executed, it may deviate from the originally planned values or only be partially executed. Onboard sensors measure these deviations, and the data is sent via telemetry. This information lets users reconstruct the actual maneuver execution and improve the modelling of spacecraft dynamics.
Once TELEMETRY data is reported, details of the original PLANNED maneuver are no longer linked to that maneuver. Essentially, the planned data is replaced by the actual execution data.

​
Reporting Telemetry via OCM

You can report the actual execution details using an OCM file. To do this:
  1. Go to the /burn-plan page.
  2. Click the Telemetry button.
  3. Upload the OCM file containing the real execution data via TELEMETRY maneuvers.
Maneuver Telemetry This method is recommended if:
  • The actual maneuver magnitude and epoch differ significantly from the planned values.
  • You want to report telemetry for multiple maneuvers at once.

​
Merging Existing Telemetry

If a user has already uploaded telemetry for a specific time range and need to include new or updated data, there are two merge strategies:
  • Update: Updates only the maneuvers that match by ID within the overlapping period. Any maneuvers without matching IDs remain unchanged.
  • Replace: Removes any existing maneuvers that overlap with the newly imported ones. This action is permanent; you cannot undo it.
Merge actions act on existing datasets, regardless if it was formerly reported as PLANNED or TELEMETRY data.
Via the API, telemetry of a maneuver can be reported using these endpoints:
  • POST /v1/maneuvers/report/file: to update existing data with telemetry values
  • POST /v1/maneuvers/report/file/override: to replace existing data with telemetry values

​
Reporting Execution Epochs

This option is recommended if a maneuver was partially executed but the maneuver’s magnitude stayed nominal. Users can update each maneuver individually through the platform:
  1. Click the edit icon in the maneuver composition section.
  2. Enter the actual execution epochs in the popup window.
When the epoch values are updated, the system automatically truncates the original planned maneuver to reflect the partial execution. Maneuver Telemetry Epoch To report partial execution programmatically via the API, send the real execution epochs to: PUT /v1/maneuvers/{maneuverID}/report/epoch.
