Description
The PassBreak Connect command allows you to specify the event that defines the boundary between passes (or revolutions) of an orbiting satellite. Most systems specify that a new pass, or orbital revolution, begins when a satellite passes through the inertial equator going north. Passes begin at the ascending node. The first pass number is the pass number of the start of the ephemeris.
| {PassOption} | Description |
|---|---|
| Ascending | Set the direction of the pass as moving North. |
| Descending | Set the direction of the pass as moving South. |
| Latitude <Value> [{Ascending | Descending}] | Set the latitude crossing at which a new pass begins. <Value> is entered in degrees. Optionally, set the direction of the pass. |
| Longitude <Value> | Set the longitude crossing at which a new pass begins. <Value> is entered in degrees. |
| Partial {Time | Angle | MeanArgOfLat} | Specify the method to use to measure partial passes. |
| CoordSys {Inertial | Fixed | TrueOfDate | TrueOfOrbitEpoch} | Specify the Coordinate system in which the latitude or longitude should be measured. |
| Number {<PassNumber> | Maintain | FromState | AtDate <PassNumber> {TimeValue}} | <PassNumber>, an integer, is used to specify the first pass number. Enter Maintain to indicate that the existing pass numbering sequence is maintained when the satellite is repropagated. Enter FromState for a satellite whose propagator is SGP4, which has its own definition for passes. Use the AtDate option to specify the date at which the first pass occurs. <PassNumber> is an integer. For valid {TimeValue} values see Time Options. |
