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

Ob detection time in ISO 8601 UTC 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.

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

Optional identifier provided by observation source to indicate the target onorbit object of this observation. This may be an internal identifier and not necessarily a valid satellite number.

Unique identifier of the reporting surveillance sensor. This ID can be used to obtain additional information on a sensor using the 'get by ID' operation (e.g. /udl/sensor/{id}). For example, the sensor with idSensor = abc would be queried as /udl/sensor/abc.

Optional identifier provided by observation source to indicate the sensor identifier which produced this observation. This may be an internal identifier and not necessarily a valid sensor ID.

Unique identifier of the transmitter. This ID can be used to obtain additional information on an RFEmitter using the 'get by ID' operation (e.g. /udl/rfemitter/{id}). For example, the RFEmitter with idRFEmitter = abc would be queried as /udl/rfemitter/abc.

Unique identifier of the reference receiver sensor. This ID can be used to obtain additional information on a sensor using the 'get by ID' operation (e.g. /udl/sensor/{id}). For example, the sensor with idSensor = abc would be queried as /udl/sensor/abc.

Optional external observation identifier provided by the source.

Optional identifier to indicate the specific tasking which produced this observation.

Unique identifier of a track that represents a tracklet for this observation.

The position of this observation within a track (FENCE, FIRST, IN, LAST, SINGLE). This identifier is optional and, if null, no assumption should be made regarding whether other observations may or may not exist to compose a track.

Boolean indicating this observation is part of an uncorrelated track or was unable to be correlated to a known object. This flag should only be set to true by data providers after an attempt to correlate to an on-orbit object was made and failed. If unable to correlate, the 'origObjectId' field may be populated with an internal data provider specific identifier.
