Orbit Determination

GET /udl/orbitdetermination/tuple

Changed on

Service operation to dynamically query data and only return specified columns/fields. Requested columns are specified by the 'columns' query parameter and should be a comma separated list of valid fields for the specified data type. classificationMarking is always returned. See the queryhelp operation (/udl/<datatype>/queryhelp) for more details on valid/required query parameter information. An example URI: /udl/elset/tuple?columns=satNo,period&epoch=>now-5 hours would return the satNo and period of elsets with an epoch greater than 5 hours ago.

Query parameters

columnsstring required

Comma-separated list of valid field names for this data type to be returned in the response. Only the fields specified will be returned as well as the classification marking of the data, if applicable. See the ‘queryhelp’ operation for a complete list of possible fields.

idOnOrbitstring

(One or more of fields 'idOnOrbit, startTime' are required.) Unique identifier of the target satellite on-orbit object. This ID can be used to obtain additional information on an OnOrbit object using the 'get by ID' operation (e.g. /udl/onorbit/{id}). For example, the OnOrbit with idOnOrbit = 25544 would be queried as /udl/onorbit/25544.

startTimestring date-time

(One or more of fields 'idOnOrbit, startTime' are required.) Start time for OD solution in ISO 8601 UTC datetime format, with microsecond precision. (YYYY-MM-DDTHH:MM:SS.ssssssZ)

firstResultinteger
maxResultsinteger

Response

OK

idstring

Unique identifier of the record, auto-generated by the system.

classificationMarkingstring required

Classification marking of the data in IC/CAPCO Portion-marked format.

startTimestring date-time required

Start time for OD solution in ISO 8601 UTC datetime format, with microsecond precision.

endTimestring date-time required

End time for OD solution in ISO 8601 UTC datetime format, with microsecond precision.

idOnOrbitstring

Unique identifier of the target satellite on-orbit object. This ID can be used to obtain additional information on an OnOrbit object using the 'get by ID' operation (e.g. /udl/onorbit/{id}). For example, the OnOrbit with idOnOrbit = 25544 would be queried as /udl/onorbit/25544.

origObjectIdstring

Optional identifier provided by the OD source to indicate the target on-orbit object of this OD solution. This may be an internal identifier and not necessarily map to a valid satellite number.

satNointeger

Satellite/Catalog number of the target on-orbit object.

aprioriIdElsetstring

Identifier of the element set used to seed this OD solution. This ID can be used to obtain additional information on an Elset object using the 'get by ID' operation (e.g. /udl/elset/{id}). For example, the Elset with idElset = abc would be queried as /udl/elset/abc.

aprioriIdStateVectorstring

Identifier of the state vector used to seed this OD solution. This ID can be used to obtain additional information on a StateVector object using the 'get by ID' operation (e.g. /udl/statevector/{id}). For example, the StateVector with idStateVector = abc would be queried as /udl/statevector/abc.

initialODboolean required

Flag indicating whether this is an initial orbit determination.

lastObStartstring date-time

The start of the time interval containing the time of the last accepted observation, in ISO 8601 UTC datetime format with microsecond precision. For an exact observation time, the lastObStart and lastObEnd are the same.

lastObEndstring date-time

The end of the time interval containing the time of the last accepted observation, in ISO 8601 UTC datetime format with microsecond precision. For an exact observation time, the lastObStart and lastObEnd are the same.

timeSpannumber double

The time span used for the OD of the object, in days.

effectiveFromstring date-time

Optional start time at which this OD solution is accurate, in ISO 8601 UTC datetime format with microsecond precision.

effectiveUntilstring date-time

Optional end time at which this OD solution may no longer be accurate, in ISO 8601 UTC datetime format with microsecond precision.

wrmsnumber double

The Weighted Root Mean Squared (RMS) of the differential correction of the target object that produced this OD state. WRMS is a quality indicator of the OD update, with a value of 1.00 being optimal. WRMS applies to batch least squares (BLS) processes.

previousWrmsnumber double

The Weighted Root Mean Squared (RMS) of the differential correction from the previous overhead pass of the satellite. Provides a point of comparison for assessing changes in the quality of the OD solution between consecutive passes.

firstPassWrmsnumber double

The Weighted Root Mean Squared (RMS) calculated for the first satellite pass in the observation span. Serves as the initial quality metric for the beginning of the observation period.

bestPassWrmsnumber double

Lowest Weighted Root Mean Squared (RMS) value achieved for any single satellite pass during the observation span, indicating the pass with the highest quality OD solution.

errorGrowthRatenumber double

Error growth rate of the OD solution in kilometers per day.

edrnumber double

Model parameter value for energy dissipation rate (EDR) in watts per kilogram.

methodstring required

Orbit determination method used to produce this record (e.g. BLS, KF, UKF, etc.).

methodSourcestring

Source of orbit determination method used to produce this record (e.g. ASW, ACTRAC, FreeFlyer, GEODYNE, GDTS, etc.).

fitSpannumber double

The fit span, in days, used in a Batch Least Squares (BLS) OD.
