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. A wealth of research has investigated the positioning accuracy of GLONASS and its impact on multi-GNSS, but rarely ...

Comparing GPS/GLONASS, GPS and GLONASS Results in a Global Network
Selçuk Üniversitesi Mühendislik, Bilim ve Teknoloji Dergisi, 2010 Teknolojinin gelişimine paralel olarak uydularla konum belirleme önemini gün geçtikçe arttırmaktadır. Günümüzde global anlamda uydularla konum belirleme olarak ilk akla gelen uydu sistemi GPS’ dir. GPS en gelişmiş ve en çok tercih edilen uydu sistemidir.

A new GLONASS FDMA model [PDF]
GPS Solutions, 2019 We introduce a new formulation of the double-differenced GLONASS FDMA model. It closely resembles that of CDMA-based systems and it guarantees the estimability of the newly defined GLONASS ambiguities. The formulation is made possible because of our defining new concept of integer-estimability and the analytical construction of a special integer matrix

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.

GLONASS Receivers Calibration [PDF]
Journal of Siberian Federal University. Engineering & Technologies, 2018 The research presents the method and the results of calibration of GLONASS receivers in the pseudorange measurement error (bias). The method is based on the application of the instruments providing traceability to national primary standards of values.
