Implementation and Test Results
The main issue is the validation of SynchroNet core synchronization algorithms in their many components: ionospheric and tropospheric models implementation, code (i.e. pseudorange: Code and Phase) based CommonView, phase based CommonView (L1 and L2), clock stability characterization by mean of CV and comparison to direct synchronization in lab (PPS biases analysis).
IGS was selected as a test bench for algorithms validation thanks to the
Here after are presented some results of both validation test results and of performance assessment of SynchroNet algorithms.
SynchroNet is at its v1.0 verification phase but its kernel is already running as core service for the Galileo Test Range (GTR), an advanced research facility for the experimentation and analysis of the Galileo Signal, for testing and certification of user terminals and support services for the development of application services. In the frame of this project, SynchroNet is used for synchronization of pseudo satellites
SynchroNet is a GNSS based time and frequency transfer System that
Through separated and successful validation campaigns using IGS network and in a full deployed system (the GALILEO Test Range), SynchroNet has proven its customizability and performances.
Currently SynchroNet is going through a further design and research
