GPS/GLONASS System Bias Estimation and Application in GPS/GLONASS Combined Positioning

2013
Multi-GNSS data analysis has become a new challenge with the development of satellite navigation systems. System bias is the key issue in Multi-GNSS data analysis, which has no recommended models within IGS community. We introduce the integrated data analysis model developed at the GNSS data analysis center of Shanghai Astronomical Observatory (SHAO ...

GLONASS R720 transmit power loss

2020
<p>All GLONASS satellites transmit navigation signals in the L1 and L2 frequency band whereas newer generations (M+ and K1) also utilize the L3 band. Previous studies have shown that the transmit power in the individual frequency bands can significantly differ for dedicated satellites. These differences are visible in the carrier-

GLONASS time and UTC(SU)

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
The paper presents the main principles of GLONASS Time generation and its synchronization to UTC(SU) as well as the main approaches that can increase the accuracy of transmitted GLONASS Time and UTC(SU).

GLONASS Carrier Phases

2003
Processing of GLONASS carrier phase observations differs from that of GPS. These differences are briefly reviewed. Presently GLONASS does not contain selective availability (SA). Simply graphing between-satellite differences reveals parts of SA that is implemented on GPS satellite signals.

Combined GPS/GLONASS navigation

NTC '91 - National Telesystems Conference Proceedings, 2002
The GPS and GLONASS systems are compared, and the satellites' status, the Magnavox GPS/GLONASS navigator, the system time difference, data processing software, and test results (combined GPS/GLONASS coverage and positioning and GLONASS receiver performance) are examined.

GLOBAL BİR AĞDA GPS/GLONASS, GPS ve GLONASS SONUÇLARININ KARŞILAŞTIRILMASI

2010
Positioning with satellites increasing its importance day by day in paralel with the technological developments. Nowadays, GPS comes to mind first, as a global positioning system. It is the most developed and prefered satellite system. With launched new satellites, GLONASS can be used alone as well as together with GPS.

IGEX-98: International GLONASS Experiment

GPS Solutions, 1999
GLONASS is a Russian military navigation satellite system. Even if the constellation is far from being operational, a large community is potentially interested in using its signal in combination with GPS to improve availability, integrity, or precision.

GPS or GLONASS?

2020
Вопросы использования различных навигационных спутниковых систем являются сегодня важными не только для правительств различных государств, но и для обычных потребителей. В данный момент существует несколько навигационных спутниковых систем. Данное исследование дает представление об основных характеристиках, достоинствах и недостатках существующих ...

An Integrated GPS/GLONASS Receiver

Navigation, 1990
Both the U.S. and the Soviet Union have been developing global satellite navigation systems that are scheduled to become operational early in this decade. With warming relations between the two superpowers, the possibility of cooperation in the civilian use of the two global navigation systems is quite good.
