heal.abstract	In the present paper, the easily expressed, in analytical form, rigorous geometrical definition of a sphere tangent to four given spheres and the investigation of solutions are synoptically cited. The applications of the aforementioned definition to the determination of position in Geodesy and especially in GPS literature are highlighted; ways to predict and avoid unfavourable situations stemming from weak or even indefinite fixation of position (outages) are mentioned.	en
