Methods

static Cesium.SpaceCatalogDataSource.categorizeSatellites()
engine/Source/DataSources/SpaceCatalogDataSource.js 287

Categorizes the satellites, represented as SpaceEntity objects, based on their orbit types. This method goes through all entities in this datasource and classifies them into their respective orbital categories (LEO, MEO, HEO, GEO, IGO, EGO, GEOIADC, GEOSYNC, SUNSYNC, SEMISYNC, POLAR, UNKNOWN). Each of these categories are arrays of SpaceEntity objects that belong to that specific orbit type. This is a computationally expensive operation, which is why it is not called automatically on entity add/modify/remove.
Example:
// Assuming instance of SpaceEntity class is spaceEntity
spaceEntity.categorizeSatellites();

loadOMM(omm, satcat) → SpaceCatalogDataSource
engine/Source/DataSources/SpaceCatalogDataSource.js 144

Name Type Description
omm ArrayBuffer | Array.<any> An Orbital Mean Elements Message (OMM)
satcat ArrayBuffer | Array.<any> An Satellite Catalog Message (SATCAT)
Returns:

update(time) → boolean
engine/Source/DataSources/DataSource.js 103

Updates the data source to the provided time. This function is optional and is not required to be implemented. It is provided for data sources which retrieve data based on the current animation time or scene state. If implemented, update will be called by DataSourceDisplay once a frame.
Name Type Description
time JulianDate The simulation time.
Returns:
True if this data source is ready to be displayed at the provided time, false otherwise.
