GET /udl/orbitdetermination/history

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

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

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

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

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.

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.

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

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.

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.

Flag indicating whether this is an initial orbit determination.

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.

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.

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

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

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

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.

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.

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.

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.

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

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

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

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

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

Flag indicating whether the ballistic coefficient was estimated during this OD solution.

Model used to estimate the ballistic coefficient.

Flag indicating whether the AGOM was estimated during this OD solution.

Model used to estimate the AGOM.

OD parameter value for the Root Mean Square (RMS) convergence criteria to successfully close the OD solution.

The number of iterations taken for the algorithm to converge on an OD solution.

Time the row was created in the database, auto-populated by the system.

Application user who created the row in the database, auto-populated by the system.

The source data library from which this record was received. This could be a remote or tactical UDL or another data library. If null, the record should be assumed to have originated from the primary Enterprise UDL.

Source of the data.

Originating system or organization which produced the data, if different from the source. The origin may be different than the source if the source was a mediating system which forwarded the data on behalf of the origin system. If null, the source may be assumed to be the origin.

The originating source network on which this record was created, auto-populated by the system.

Indicator of whether the data is REAL, TEST, EXERCISE, or SIMULATED data:

REAL: Data collected or produced that pertains to real-world objects, events, and analysis.

TEST: Specific datasets used to evaluate compliance with specifications and requirements, and for validating technical, functional, and performance characteristics.

EXERCISE: Data pertaining to a government or military exercise. The data may include both real and simulated data.

SIMULATED: Synthetic data generated by a model to mimic real-world datasets.
