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.

Cross-calibrations of multi-GNSS Receiver Chains
2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019GNSS receiver chain calibration is a pre-requisite for accurate GNSS time transfer and GNSS time dissemination, which becomes particularly relevant in a competitive multi-GNSS environment. Measurement of GNSS chains based on an absolute calibration approach have been proposed but are not yet operational due to the limited number of results and the ...

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 +2 more sources
Simulation of Multi-GNSS Observations
Cosmic ResearchIn this paper, expressions for high-precision simulation of multi-GNSS observations received in low Earth orbit are given. Based on this observation model, the real spacecraft orbit was refined. Based on real data from the GRACE space project, the results were compared with simulated measurements from foreign software.

Precise Real-Time Multi-GNSS PPP
2015Global 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 ...
