GrafNav post-processing software is a powerful, highly configurable processing engine that allows for the best possible static or kinematic GNSS accuracy using all available GNSS data. Support of data formats from most single and multi-frequency commercial receivers means GrafNav will likely work with your existing hardware. A full suite of data and solution visualization and diagnostic tools is available for quality assurance. Precise satellite clock and orbit data can be downloaded from within GrafNav to achieve sub-10 cm position accuracy using PPP with kinematic trajectories.

No matter the type of project, GrafNav can be configured to optimize your results. The software can easily make use of project specific base station data, or use publicly available reference station data to achieve centimetre level position accuracy. GrafNav also supports multi-base processing for projects that cover large areas. A float static solution is available for long and/or noisy baselines. Built-in ionospheric processing improves accuracies for dual-frequency users.

Enhanced GNSS Accuracy

GNSS technology is used to compute position and velocity for a variety of real-time applications, including vehicle navigation and tracking. The real-time accuracy of GNSS however, is limited by real-time transmission of correction data. Further, in many applications where absolute position accuracy is critical, the position information is not required in real-time. For these applications, the accuracy of the GNSS position and velocity solution can be greatly improved by post-processing.
