The set of satellite systems for global navigation that are functioning or are expected to be launched in the future, in English are called GNSS (Global Navigation Satellite Systems), whereas in Albanian it will be SSNG (Sistemi satelitor për navigim global). This system allows determining the position in the whole globe…

Theoretically in the simultaneous observation of the high-precision GPS network solution mode, the selection of the independent baseline vector can be arbitrary with the same adjustment. But in the real situation, the results varies in different selections for the model of baseline solution is imperfect[1].
