Spacecraft.OrbitNumber(Variable) Method

Top 

Description

Returns the number of times a Spacecraft has orbited the Earth (revolutions). It is incremented each time the spacecraft crosses the ascending node. For an orbit inclination close to zero degrees, the OrbitNumber is incremented based on the orbit period. In the case of backwards propagation, the OrbitNumber is decremented as above. The orbit number can be referenced from an initial value.

 

This method has been Deprecated. Please use the Spacecraft.OrbitNumberCumulative property instead.
