Accurate Kinematic Trajectory Determination
The airborne mapping industry worldwide relies on GrafNav to produce accurate maps and DEMs, often in challenging
environments. These applications require reliability, high accuracy and rigorous quality control. Jobs over large
geographic areas can include long baselines, which have traditionally made accuracy requirements difficult to
achieve. GrafNav features such as multiple base station processing, tropospheric bias modelling and AdVance RTK
allow for precise accuracy for even the longest flights.
Differential GNSS provides excellent results, but base station setup can be problematic. Multiple features available
in GrafNav simplify differential operation. High elevation flights can often be affected by atmospheric error effects
that lead to poor elevation accuracy. GrafNav mitigates these errors using embedded advanced atmospheric
modelling. Base station coordinate errors can also cause problems. GrafNav’s Precise Point Positioning (PPP)
filter can be used to accurately verify or even solve the base station coordinates. PPP processing can also
be used in kinematic mode to eliminate the base station(s) from your workflow entirely. When used with
downloadable clock and orbit data the GrafNav PPP filter can provide accuracies of 5–30 cm for airborne data.
Receiver Independent Processing
GrafNav/GrafNet supports 28 different raw data formats, including RINEX, as worldwide users often employ
various types of GPS/GLONASS receivers. A flexible data conversion utility automatically detects most of
these formats. For those users without local base stations, the included download utility permits access to
several thousand continuously operating stations from networks such as CORS, IGS, IGN (France), GSI
(Japan), ARGN (Australia) and more.
Support for Special Applications
GrafNav/GrafNet can be provided as a developer’s kit that permits users to access the processing DLLs.
For a more simple software interface, GrafNav has an extensive number of command line functions that
makes it possible to completely automate processing. The GPS internet data download utility and the
raw data conversion utility also have command line options to enable automation of the entire process.

GrafNav Batch
Can be used to batch process multiple remotes or combine individual trajectories from multiple base stations. Support for up to 128 bases or remotes and has most of the same features as GrafNav.
AutoNav
One-step function to automatically convert raw data, select and download nearest base stations from the internet, resample base data to proper interval, and then process and export results. GrafNav compatible configuration files are created to ease quality control.
Datalogger
A real-time logger is included for Windows and WinCE. It permits users to log Waypoint or receiver native formats, while stations can also be marked and logged.
