orbit library
TLE and NORAD SGP4/SDP4/SGP8/SDP8 Implementation for Dart and Flutter.
Classes
- Earth
- Represents Earth planet.
- EarthCenteredEarthFixed
- Earth-centered, Earth-fixed is a cartesian spatial reference system that represents locations in the vicinity of the Planet (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.
- EarthCenteredInertial
- Earth-centered inertial (ECI) coordinate frames have their origins at the center of mass of Planet and are fixed with respect to the stars.
- Geodetic
- Encapsulates geocentric coordinates.
- KeplerianElements
- The Keplerian Elements.
- LookAngle
- Encapsulates topo-centric coordinates.
- Orbit
- The main class to start orbit calculation.
- OrbitalState
- RV Pair for satellite state.
- Planet
- Abstract planet for calculations.
- SGP4
- SGP4 Calculator.
- Topocentric
- Topocentric parameters.
