Precise Point Positioning Using Combined GPS and GLONASS Observations
Precise Point Positioning (PPP) is currently based on the processing of only GPS observations. Its positioning accuracy, availability and reliability are very dependent on the number of visible satellites, which is often insufficient in the environments such as urban canyons, mountain and open-pit mines areas. Even in the open area where sufficient GPS satellites are available, the accuracy and...
متن کاملNetwork-based RTK Positioning Using Integrated GPS and GLONASS Observations
With the recent rapid revival of the GLONASS constellation, it is possible for the GLONASS system to provide Full Operational Capability (FOC) service before the end of 2011. CDMA signals are now additionally modulated onto the first GLONASS-K satellite which was launched on February 26, 2011. It is envisaged that GNSS users will benefit from more visible satellites, better precision and higher...
متن کاملSea level measurements using multi-frequency GPS and GLONASS observations
Global Positioning System (GPS) tide gauges have been realized in different configurations, e.g., with one zenith-looking antenna, using the multipath interference pattern for signal-to-noise ratio (SNR) analysis, or with one zenithand one nadir-looking antenna, analyzing the difference in phase delay, to estimate the sea level height. In this study, for the first time, we use a true Global Nav...
متن کاملClock Synchronization Using Gps/glonass Carrier Phase
Clock synchronization by means of GPSIGLONASS is proposed. The GPSIGLONASS receivers with the external frequency input interface are used in our system. While the remote OCXO (OvenControlled Crystal Oscillator) clock and the primary H-maser clock are connected to the receivers, the frequency o s e t of the remote clock with respect to the primary clock can be estimated by performing the linear-...
متن کاملGPS & GLONASS RX - theory
Besides amateur-radio satellites, the most interesting satellites for radio amateurs are weather (imaging) satellites: radio amateurs have successfully built weather-satellite image reception equipment for all known weather satellites and all known image transmission standards. Radioamateurs also pioneered satellite TV reception using small antennas much earlier than this became a mass-produced...
