The basic observation equations for GPS-phase measurements in the single-, double- and triple-difference mode are developed. It is assumed that the orbit of the satellites is unknown and, consequently, therefore part of the solution.

The solution of such a system of observation equations is presented. It enables the user to determine 3d-baseline components with high accuracy without prior information of the P-code.
