Generation of Virtual Rinex Stations (VRS) is a feature available in the C4Gnet.XYZ Reference Data Shop (RDS). This feature requires a subscription to the Reference Data Shop, and it uses network processors and CORS data to create static files modeled from 6-9 stations around a location you specify. To create a VRS users just enter the coordinates of where they want a virtual reference station and the RDS generates RINEX files for the time and duration specified by the user. VRS was developed to reduce the length of static sessions, but recently, UAS (drone) operators have found it is a good option for PPK post-processing.

The Reference Data Shop is a Web-based application that allows users to easily access RINEX files for post-processing through a simple interface. System users can create custom RINEX files to meet their needs in standard RINEX or compact RINEX data storage formats. Choose from data intervals of 1, 2, 5, 10, 15, 20, 30 or 60 seconds. Data can be emailed or downloaded immediately or at any future time for added convenience. Data is available from all Louisiana NGS CORS and every other site in the C4GNet RTN.
