High-precision GNSS Post-processing software
GrafNav / GrafNet is a GPS / GLONASS post-processing software package designed and developed on the basis of Windows environment. By the use of advanced algorithms, it can process the data measured from GPS single-frequency, dual-frequency and GLONASS system with a fast calculation velocity and high precision. GrafNav / GrafNet software package includes three modules: GrafNav, GrafNet and Utilities. Its core adopts a carrier phase dynamic Kalman filter.
