A Study on Satellite Geometry Variation for Multi-GNSS from India

Satellite navigation (satnav) systems are now popular with different usable satnav systems. Accuracy of navigation solution depends on satellite geometry; an integrated mode of operation using more than one system is now possible that is supposed to provide better satellite geometry. This paper presents a study on obtainable satellite geometry involving GPS and GLONASS in stand-alone and mixed modes of operation based on collected data from different parts of India.
