Kinematic PPP Using Mixed GPS/Glonass Single-Frequency Observations
Nowadays, Precise Point Positioning (PPP) is a very popular technique for Global Navigation Satellite System (GNSS) positioning. The advantage of PPP is its low cost as well as no distance limitation when compared with the differential technique.

Decadal evolution of GPS, GLONASS, and Galileo mean orbital elements
We examine the decadal evolution of GPS, GLONASS, and Galileo satellite orbital elements, including the semi-major axis, inclination, eccentricity, right ascension of the ascending node, and the argument of perigee.
