The Receiver-Independent Exchange (RINEX1) format is a broadly accepted, receiver independent format for storing GPS data. It features a non-proprietary ASCII file format that can be used to combine or process data generated by receivers made by different manufacturers.
Use the NovAtel’s Convert utility to produce RINEX files from NovAtel receiver data files. The Convert utility is available in the NovAtel Application Suite application.
