feat: add kinematics support and Altitude types to Entity#295
Merged
Conversation
Adds a new optional `kinematics` field to the `Entity` type along with a suite of new altitude-related types for representing altitude data across multiple reference datums. The `kinematics` field offers higher-granularity kinematics data preferred for Track Entities as an alternative to `location`/`locationUncertainty`. Key changes: - Add optional `kinematics` field with getter and builder methods to `Entity` - Add new `Altitude` type aggregating multiple altitude reference datums - Add `AltitudeAboveGroundLevel`, `AltitudeAboveMeanSeaLevelEgm96`, `AltitudeAboveMeanSeaLevelPressure`, `AltitudeAboveSeaFloor`, and `AltitudeAboveStandardDatumPlanePressure` types

What's New
This release introduces richer kinematics modeling for entities. A new
Entity.getKinematics()accessor andEntity.Builder.kinematics()builder method let you supply higher-granularity kinematics data, which is the preferred approach for Track Entities as an alternative to the existinglocation/locationUncertaintyfields.The kinematics feature is backed by a family of new types.
Kinematics,KinematicsGeodetic, andKinematicsGeocentricconvey location, velocity, acceleration, attitude, and measurement time in both geodetic and geocentric (ECEF) reference frames. These are supported by new location typesLocationGeodetic(WGS84) andLocationGeocentricEcef, along withVec3andTMat3primitives for 3D vectors and 3x3 covariance matrices.Altitude handling has also been expanded. A new
Altitudetype aggregates measurements across multiple reference datums, backed by datum-specific types covering above ground level, mean sea level (EGM96 and pressure), sea floor, standard datum plane pressure, WGS84 ellipsoid, and below sea surface. NewAltitudeProvenanceandAltitudeProvenanceSourceTypetypes capture how an altitude value was sourced, such as from a barometer, GNSS, or sonar.See full changelog
