RINEX files from an array of colocated receivers: low-cost, software and hardware simulator.

The real data applied in the low-cost demonstration test was collected for nine sites from 5 to 17 July 2022, with a sampling rate of 30 s. These nine sites are located on the roof of the Institute of Geodesy and Geoinformatics (IGG) at the Wrocław University of Environmental and Life Sciences in Poland, and equipped with multiple u-blox ZED-F9P receivers connected to rooftop GNSS antennas on a platform. These files are available at: https://zenodo.org/records/10209845 The simulation data was generated with Spirent GNSS simulator, which is able to generate pseudorange and carrier-phase observations based on the user-defined station coordinates and observation time. In addition, the generated GNSS signals can be transmitted to an external GNSS receiver on demand. Accounting for the effect of receiver noises, we perform the simulation with two modes: virtual mode (Spirent_Virtual.zip) and hardware mode (Spirent_Hardware.zip), representing the application of GNSS simulator without and with the connection to the u-blox ZED-F9P receiver, respectively.
