1982年10月12日 · GLONASS is the acronym for GLObalnaya NAvigatsionnaya Sputnikovaya Sistema in Russian. The role of the GLONASS satellite navigation system is similar to the GPS of the United States, the Galileo satellite positioning system of Europe, and the BeiDou satellite navigation system of China [1]. The system was first developed in the Soviet Union ...

2016年3月1日 · Double differencing for GLONASS does either not eliminate receiver clock biases or causes the loss of the integer nature of ambiguities. Currently, there are two strategies for GLONASS ambiguity resolution: the first strategy is to process carrier phase in unit of cycles keeping the integer nature of ambiguities.

2024年10月1日 · For GLONASS M+ satellites, anomalous yaw accelerations during rate-limited noon turns could be revealed that cause yaw offsets of up to 20° with respect to established GLONASS-M attitude models. Overall, the triple-carrier technique lends itself as a viable tool for continued monitoring of GLONASS-M+ and -K2 yaw angles.

2022年3月1日 · The GLONASS SISRE is the largest among all constellations, with an average value of 2.222 m. The worse GLONASS SISRE can mainly be attributed to the FDMA modulation (Montenbruck et al., 2018). The group delays coming with the FDMA modulation cannot be divided into a sum of satellite- and receiver-specific contributions, and they are generally ...

2020年11月1日 · The use of GPS + GLONASS resulted in the accuracy of several cm. Kouba [34] showed how the accuracy of the IGS products changed: the accuracy of the orbits of 30 cm in 1994 decreased to below 2 cm in 2015. In 2016, static GPS + GLONASS positioning using magicGNSS software was used by Pandey et al. [51]. About 60% more observed satellites …

2013年2月1日 · Four IGS analysis centers provide GLONASS precise orbit products on a regular basis, including CODE (Center for Orbit Determination in Europe, Switzerland), IAC (Information – Analytical Center, Russia), ESA/ESOC (European Space Operations Center, Germany) and BKG (Bundesamt für Kartographie und Geodäsie, Germany).

2021年4月1日 · The GLONASS constellation has been fully recovered since October 2011, and 24 satellites were deployed again. The satellite information, including the pseudo-random noise (PRN), satellite vehicle number (SVN), valid date, invalid date, and satellite type, as of April 2018, are listed in Table

2017年7月26日 · A full GLONASS constellation consisting of 24 operational satellites in three orbital planes has been completely revitalized since 2012. Each GLONASS satellite operates in a nearly circular orbit with an altitude of approximately 19,100 km, and completes the orbit in approximately 11 h 16 min. Each orbital plane has an inclination angle of 64.8 ...

2023年11月1日 · The maximum differences for GLONASS receivers in these same stations were 1.56, 1.66, 1.89, 3.16, and 2.25 ns. It is noteworthy that the maximum GLONASS DCB difference was very close to GPS DCB in all stations, which can be attributed to the fact that both systems are affected by similar temperature and humidity conditions.

2011年1月4日 · The Earth–spacecraft–Sun angle ϵ 0 of a GLONASS-M satellite at the entrance and the exit of the umbra (penumbra) is ±14.20° (±14.73°). A GLONASS-M satellite traveling with a mean orbital angular velocity of μ ˙ = 0.00888 ° /s around the Earth may therefore need up to around 53 min for its passage through the umbra.
