Look ahead duration methods.
| Member | Value | Description |
|---|---|---|
| eExtrapolate | 0 | Extrapolate: STK uses the last two history points to extrapolate attitude into the Look Ahead window. This method is best if attitude changes slightly over time. |
| eHold | 1 | Hold: Attitude remains the same from the last data point. This method is best when fixed attitude is more reliable than an approximate value. |
