Analyses of GLONASS and GPS+GLONASS Precise Positioning Performance in Different Latitude Regions
Remote Sensing, 2022 The orbital inclination angle of the GLONASS constellation is about 10° larger than that of GPS, Galileo, and BDS. Theoretically, the higher orbital inclination angle could provide better observation geometry in high latitude regions.

Evalution of the Accuracy and Performance of Multi-GNSS (MGEX) Positioning for Long Baselines by Using Different Software [PDF]
Journal of Geodesy and Geoinformation Science, 2023 The Global Positioning System (GPS) is a GNSS constellation, but GNSS is not always GPS. GPS is one of the GNSS constellations used around the world. The GNSS constellations include GPS (US), QZSS (Japan), Beidou/BDS (China), Galileo (EU), and GLONASS ...

GLONASS ambiguity resolution [PDF]
GPS Solutions, 2019 A new integer-estimable GLONASS FDMA model is studied and analysed. The model is generally applicable, and it shows a close resemblance with the well-known CDMA models. The analyses provide insights into the performance characteristics of the model and concern a variety of different ambiguity-resolution critical applications.
