Computing Dilution of Precision (DOP) For 4 or More Satellites
For each satellite n define:
- a n,1 = sin az cos el
- a n,2 = cos az cos el
- a n,3 = sin el
Where:
el = Local elevation angle, and az = Local azimuth angle (from North)
Next, form the line-of-sight matrix A for all satellites used in the solution:
