| Figure F-1 Distance Observation |
Equation F-1 is the distance bertween two points in terms of their coordinates.
 |
Equation F-1 |
|
NA, EA: At point coordinates |
|
To apply a Taylor Series, patial derivatives of Equation F-1 are taken with respect to each coordinate of both points. The partial derivative for NA is:
Similarly, the remaining partial derivatives are:
Equation F-2 is the distance observation equation, evaluated at initial coordinate approximations.
