Spacecraft.FOVTimes(Spacecraft) Method

Top

Description

Returns the entry and exit times when spacecraftToView enters and leaves the Spacecraft's field of view as well as the azimuth and elevation of the argument in the Spacecraft's first active Sensor's coordinate frame. If the Spacecraft has no active Sensors, the azimuth and elevation are reported in the Spacecraft's body coordinate frame.

Arguments

spacecraftToView
Description:	Target Spacecraft to use in the field of view calculation.

Return Value

Type:

string

Returns the entry and exit times when the argument Spacecraft, GroundStation, Star, or celestial body enters and leaves the Spacecraft's field of view as well as the azimuth and elevation of the argument in the Spacecraft Sensor's coordinate frame. If the Spacecraft has no active Sensors, the azimuth and elevation are reported in the Spacecraft's body coordinate frame.

The FF_Preferences.IntervalEventReportingBehavior property controls whether the start and end of propagation are reported as events. By default, if contact starts before the beginning of the propagation span, FreeFlyer will label the start of the propagation as the start of contact. If contact extends past the end of the propagation span, FreeFlyer labels the end of propagation as the end of contact.

myString1 = mySpacecraft1.FOVTimes(mySpacecraft2);
