GLONASS-R: GNSS reflectometry with an FDMA based satellite navigation system
This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the signals can become a valuable data source, from which geophysical properties can be deduced. This approach, called GNSS-Reflectometry (GNSS-R), can be used to develop i...
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...
متن کاملStatistical Characterization of GLONASS Broadcast Ephemeris Errors
For critical navigation applications such as aircraft approach and landing, there is a general desire to use multi-constellation global navigation satellite systems (GNSS) to enhance availability and reliability. The Russian Global Navigation Satellite System (GLONASS) is so far the only other constellation nearly as developed as the Global Positioning System (GPS). A thorough characterization ...
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 System Bias Estimation and Application in GPS/GLONASS Combined Positioning
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). Based on the routine GNSS data analysis at ...
