Spacecraft.AvgLongDescendingNodeErrorKm(Variable, Variable) Method
Returns a moving average of the Spacecraft's longitude of the descending node error.
The longitude of descending node error is the offset from a user-defined global reference longitude grid measured at the descending node, also referred to as a repeating groundtrack grid. The moving average will use a maximum of 288 data points to determine the average. A simple average is returned when the number of data points available is less than 288 points. Once at least 288 data points are available, the returned average value is an average over the most recently calculated set of data points, where the number of points in the set equals 288. (Assuming a 300 second integration step size, 288 points generates an average calculation over a day).
This property requires two arguments by which the user defines the repeating groundtrack grid. The two arguments are the base longitude, used to initialize the repeat groundtrack grid, and the repeat cycle, the number of orbits before the Spacecraft repeats the repeat groundtrack grid. This property returns a scalar value. Note that this property is Earth-specific.
