Spacecraft.FOVTimes(Spacecraft, Sensor, Array, Array) Method

Top

Description

Returns the entry and exit times when spacecraftToView enters and leaves the Spacecraft's field of view.

Timing Precision Mode

This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Note: This is an interval method. See the Interval Methods page for more information.

Note: This method has a state. See the Methods and Properties with State page for more information.

Method Signature

Spacecraft.FOVTimes(	Spacecraft spacecraftToView,
	Sensor sensorToUse,
	Array EventTime,
	Array EventType)

Arguments

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

sensorToUse
Description:	Sensor to use for the field of view calculation.

EventTime

Description:

The time that the event occurred.

The FF_Preferences.IntervalEventReportingBehavior property controls whether the start of propagation is reported as an event. 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.

EventType
Description:	The type of the event that occurred. Event Type == 1 is entry into Contact. Event Type == 2 is exit from Contact.

Return Value

Type:

number

Returns the number of elements filled into EventType and EventTime arrays.

Syntax

myVariable1 = mySpacecraft1.FOVTimes(mySpacecraft2, mySensor1, myArray1, myArray2);
