Detailed Description
Satellite orbital mechanics.
Constructor & Destructor Documentation
◆ Satellite()
|
explicit |
Initialize satellite from two line ephemeris data.
- Parameters
-
ephemeris An array containing the name, line 1, and line 2
Member Function Documentation
◆ celest()
| std::tuple< double, double > Satellite::celest | ( | ) |
Access the satellite celestial co-ordinates.
- Returns
- a tuple containing latitude and longitude in Radians. North and East hemispheres have positive values.
◆ checkSatEpoch()
|
inline |
Determine if the sat epoch is known to be good.
- Returns
- true if good.
◆ eclipsed()
| bool Satellite::eclipsed | ( | const Sun & | sp | ) |
Determine if the sun is eclipsed by the current predicted position.
- Parameters
-
sp The Sun object.
- Returns
- true if eclipsed.
◆ epoch()
| DateTime Satellite::epoch | ( | ) | const |
Access the epoch of the satellite.
- Returns
- the DateTime of the epoch.
◆ geo()
| std::tuple< double, double > Satellite::geo | ( | ) |
Access the sub-satellite geographical co-ordinates.
- Returns
- a tuple containing latitude and longitude in Radians. North and East hemispheres have positive values.
◆ getName()
|
inline |
Access the satellite name.
- Returns
◆ period()
| double Satellite::period | ( | ) | const |
Access the satellite orbital period.
- Returns
- the period in days per revolution.
◆ predict()
| void Satellite::predict | ( | const DateTime & | dateTime | ) |
Predict the satelite position at given DateTime.
- Parameters
-
dateTime
◆ topo()
| std::tuple< double, double, double, double > Satellite::topo | ( | const Observer & | obs | ) |
Convert satellite co-ordinates to an observer frame.
- Parameters
-
obs the Observer object
- Returns
- a tuple containing: altitude (the angle of elevation), azimuth, range, range_rate
◆ viewingRadius()
| double Satellite::viewingRadius | ( | double | alt | ) |
Compute the viewing radius from the sub-satellite geographical location for a given altitude (angle of elevation).
- Parameters
-
alt - angle of elevation in Radians
- Returns
- the great-circle viewing radius in Radians.
