Capabilities Covered
This lesson covers the following STK Capabilities:
- Aviator Pro
Stationkeeping
The Stationkeeping strategy is a horizontal plane strategy in which the aircraft orbits a point relative to a stationary or moving object.
| Field | Description |
|---|---|
| Target |
Select an object in the scenario that the aircraft will target during the maneuver. |
| Pos/Vel Strategies |
Position and velocity strategies for the target object. The following strategies are available:
|
| Tgt Pos/Vel Resolution |
The frequency of sampling of the target object's position and velocity; interpolation of the object's position will be performed between sample points. The lowest recommended value for this property is 0.1 sec, but the lowest possible value is 0.001 sec. At the lowest value, STK's Aviator capability will use the native position and velocity of the target object; this can result in dramatically slow performance when the target object is another Aviator aircraft, since STK is performing double integration calculations in such a case. |
| Max Tgt Speed Fraction | The maximum speed, relative to the target, at which the aircraft will attempt to remain on station; if this value is exceeded, the aircraft will stop the procedure. |
Station
| Field | Description |
|---|---|
| Rel Bearing |
The bearing relative to the target that the aircraft will hold. |
| Rel Range |
The range from the target where the aircraft will hold. |
| Desired Radius | The goal radius of the holding circle that the aircraft will fly while waiting on station. |
| Turn Direction | Select an option to define if the aircraft turns left or right into the holding circle. |
Maneuver Factor
The Maneuver Factor defines a dimensionless factor that influences how tightly or gently the aircraft will maneuver. At its most aggressive setting, the factor will force the strategy to achieve the specified performance values; at its most gentle setting, the factor will allow the strategy to tolerate the most deviation from those values.
Control Limits
Select a method to define the control limits (which constrain performance) of the aircraft during the maneuver.
