Precise Real-Time Multi-GNSS PPP [PDF]
, 2015 Global Navigation Satellite System (GNSS) technology has undergone enormous developments over the last three decades. The majority of PNT (Positioning, Navigation and Timing) applications are now based on GNSS. This increasing dependence on GNSS technology is acknowledged by several nations, some of which are even developing their own regional or ...

Multi-GNSS time transfer based on the CGGTTS
Metrologia, 2019This paper studies the use of multiple GNSS constellations for time transfer. The performances of each constellation are compared to one another. We show that, with its current constellation, Galileo already provides time transfer results with the same or better performances than GPS, for which some time links are affected by a diurnal variation.

Multi-GNSS time transfer with CGGTTS-V2E
2018 European Frequency and Time Forum (EFTF), 2018A software tool was developed at the Royal Observatory of Belgium for building the CGGTTS products from the RINEX observation and navigation files provided by the GNSS receivers. This software has been completely re-built in order to increase the robustness, the computation speed, and to include GPS, GLONASS, BeiDou and Galileo.

Broadcast versus precise ephemerides: a multi-GNSS perspective
GPS Solutions, 2014A consistent analysis of signal-in-space ranging errors (SISREs) is presented for all current satellite navigation systems, considering both global average values and worst-user-location statistics. The analysis is based on 1 year of broadcast ephemeris messages of the Global Positioning System (GPS), GLONASS, Galileo, BeiDou and QZSS collected with a ...

Integrated Multi-GNSS Receivers
The challenges of multi-band, multi-system (i.e., multi-) GNSS reception are higher bandwidths, higher sampling rates, and often multiple reception chains. All of these lead to an increase in complexity, size, and power consumption, especially for integrated radio frequency (RF) front-ends.openaire +1 more source
