--- title: "GET /udl/onboardnavigation" method: GET path: "/udl/onboardnavigation" tags: ["Observation"] --- # GET /udl/onboardnavigation `GET /udl/onboardnavigation` ## Request - Base URL: `https://unifieddatalibrary.com` - URL: `https://unifieddatalibrary.com/udl/onboardnavigation` - Auth: none declared Service operation to dynamically query data by a variety of query parameters not specified in this API documentation. See the queryhelp operation (`/udl//queryhelp`) for more details on valid/required query parameter information. ## Query parameters - `startTime` string, date-time, required - `firstResult` integer - `maxResults` integer ## Response `200` OK - OnboardNavigationAbridged[] - `id` string: Unique identifier of the record, auto-generated by the system. - `classificationMarking` string, required: Classification marking of the data in IC/CAPCO Portion-marked format. - `idOnOrbit` string: Unique identifier of the primary satellite on-orbit object. - `satNo` integer: Satellite/catalog number of the target on-orbit object. - `origObjectId` string: Optional identifier provided by the data source to indicate the target object of this record. This may be an internal identifier and not necessarily map to a valid satellite number. - `startTime` string, date-time, required: Start time of the sensor data, in ISO 8601 UTC format. - `endTime` string, date-time: End time of the sensor data, in ISO 8601 UTC format. - `esId` string: Unique identifier of the parent EphemerisSet, if this data is correlated with an Ephemeris. If multiple nav sensor records are required, this ID may be associated with each of those records if each is synced to the ephemeris points. - `starCatName` string: The name or identifier the star catalog in use. - `starCatLoadTime` string, date-time: The last load time of the current star catalog onboard this spacecraft. - `idStateVector` string: Unique identifier of the last onboard state vector. - `ts` string[]: Array of epochs of the observations, in ISO 8601 UTC format. The epochs are assumed to correspond to all sensor data in this record. If sensors do not share a common epoch then separate records should be generated. - `referenceFrame` 'J2000' | 'EFG/TDR' | 'ECR/ECEF' | 'TEME' | 'ITRF' | 'GCRF': The reference frame in which the sensor derived positions are provided. If the referenceFrame is null it is assumed to be J2000. Note that this frame is assumed to apply to all of the sensor data in this record. If onboard sensors process positional estimates in different frames then separate records should be generated. - `sunSensor` array[]: Arrays of spacecraft position (X, Y, Z), in km, in the specified referenceFrame, based on the onboard sun sensor, at each epoch. - number[] - `mag` array[]: Arrays of spacecraft position (X, Y, Z), in km, in the specified referenceFrame, based on the onboard magnetometer, at each epoch. - number[] - `starTracker` array[]: Arrays of spacecraft position (X, Y, Z), in km, in the specified referenceFrame, based on the onboard star tracker, at each epoch. - number[] - `deltaPos` array[]: Arrays of spacecraft delta position (X, Y, Z), in km, in the specified referenceFrame, between the onboard state and the last accepted sensor position. - number[] - `createdAt` string, date-time: Time the row was created in the database, auto-populated by the system. - `createdBy` string: Application user who created the row in the database, auto-populated by the system. - `source` string, required: Source of the data. - `origin` string: 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. - `origNetwork` string: The originating source network on which this record was created, auto-populated by the system. - `dataMode` 'REAL' | 'TEST' | 'SIMULATED' | 'EXERCISE', required: 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. ## Other responses - `400`: Bad Request - `401`: Invalid/Missing User Credentials - `403`: User Is Not Authorized - `405`: Method Not Allowed - `406`: MediaType Not Accepted by Request Headers - `429`: Rate of Requests Exceeds Allowed Limit - `500`: Internal Server Error ## Changes > 12 revisions in range; 1 could not be searched. - **2025-05-29** `4e1cbc17e814`: 2 info - added the new optional `query` request parameter `firstResult` - added the new optional `query` request parameter `maxResults` - **2025-04-16** `75f764c843a9`: 2 info - api operation id `findAll_72` removed and replaced with `` - the endpoint scheme security `BasicAuth` was removed from the API [Operation history](https://skmtc.dev/bluestaq/apis/unified-data-library-services-api/changes/udl/onboardnavigation/get.md) --- [API](https://skmtc.dev/bluestaq/apis/unified-data-library-services-api.md) - [All operations](https://skmtc.dev/bluestaq/apis/unified-data-library-services-api/llms.txt) - [OpenAPI document](https://skmtc.dev/bluestaq/apis/unified-data-library-services-api/revisions/bd17bc53681e?raw)
