3. Materials and Methods
Assuming that the standard deviation is 0.3 m, make a MATLAB
program to calculate receiver position.
1. Choose any one control point
2. Calculate the receiver position epoch by epoch
3. Plot the relative position changes with respect to the time
changes (hour)
4. Overplot the GDOP changes with respect to the time changes
Note:
1) Use the CP positions as initial inputs for iterations
2) Use only the GPS data with elevation angle ` 15¡Æ
3) Use only the epoch data with the number of satellites ` 3
