# GET /udl/launchdetection/tuple

`GET /udl/launchdetection/tuple`

## Request

- Base URL: `https://unifieddatalibrary.com`
- URL: `https://unifieddatalibrary.com/udl/launchdetection/tuple`
- Auth: none declared

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

- `columns` string, required
- `firstResult` integer
- `maxResults` integer

## Response `200`

OK

- LaunchDetectionFull[]
  - `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.
  - `launchTime` string, date-time: Time of Launch.
  - `messageType` string, required: Type of message for the data.
  - `launchLatitude` number, double: Geodetic Latitude of launch origin (in Degrees). -90 to 90 degrees (negative values south of equator).
  - `launchLongitude` number, double: Geodetic Longitude of launch origin (in Degrees). -180 to 180 degrees (negative values west of Prime Meridian).
  - `launchAzimuth` number, double: Angle measured clockwise from North for the launch heading (in Degrees).
  - `raan` number, double: Orbit Right Ascension of Ascending Node (in Degrees).
  - `inclination` number, double: Orbit Inclination (in Degrees).
  - `observationTime` string, date-time, required: Time of observation.
  - `observationLatitude` number, double, required: Latitude of launch vehicle at observation time (in Degrees). -90 to 90 degrees (negative values south of equator).
  - `observationLongitude` number, double, required: Longitude of launch vehicle at observation time (in Degrees).
  - `observationAltitude` number, double: Altitude of launch vehicle at observation time (in KM).
  - `stereoFlag` boolean: Flag indicating multiple observers were used.
  - `highZenithAzimuth` boolean: Flag indicating that the Launch azimuth is uncertain due to near vertical flight path.
  - `sequenceNumber` integer, required: Integer indicating how messages should be sequenced for a specific event.
  - `eventId` string: Id to be able to correlate different messages to a specific event.
  - `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.
  - `descriptor` string: Optional source-provided and searchable metadata or descriptor of the data.
  - `tags` string[]: Optional array of provider/source specific tags for this data, where each element is no longer than 32 characters, used for implementing data owner conditional access controls to restrict access to the data. Should be left null by data providers unless conditional access controls are coordinated with the UDL team.
  - `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.
  - `createdAt` string, date-time: Time the row was created in the database.
  - `createdBy` string: Application user who created the row in the database.
  - `updatedAt` string, date-time: Read-only time the row was updated in the database, set automatically by the system on update.
  - `updatedBy` string: Application user who last updated the row in the database, set by the system automatically and ignored on create/edit operations.
