 Post-processing Software Packages
NovAtel's Waypoint® Products Group offers GPS post-processing software packages including Waypoint GrafNav (a static/kinematic baseline processor) and Waypoint GrafNet (a static baseline processor/network adjustment package). Both of these products have an easy to use graphical interface and use the same precise GPS processing receiver. This processing receiver has undergone years of development effort and has been optimized to give the highest precision with the least amount of operator intervention. Waypoint Inertial Explorer™ is also available for users who wish to integrate IMU sensor arrays with GPS information.  Waypoint Inertial Explorer®Waypoint Inertial Explorer (GPSIMU) post-processing software suite is aimed at users who wish to integrate rate data from six degrees of freedom IMU sensor arrays with GPS information processed via Waypoint GrafNav, which is included. Waypoint Inertial Explorer is designed to utilize strapdown accelerometer (Dn) and angular rate (Dq) information to produce high rate coordinate and attitude information from a wide variety of IMUs, including high-accuracy navigation grade to inexpensive MEMS (Micro Electro-Mechanical Systems) sensor types. Inertial Explorer can be used to process both loose and tightly coupled GNSS/IMU solutions. Loosely coupled processing is recommended for airborne or open sky surveys. Tightly coupled solutions provide much improved accuracy in challenging GNSS signal environments such as ground vehicle surveys in urban environments.  Waypoint GrafNav/GrafNet™Waypoint GrafNav/GrafNet post-processes raw GPS data from most available GPS receivers. Using data from both a roving station and as many as eight base stations, accurate position computations are available with Waypoint GrafNav. Waypoint GrafNav can also process a single static baseline. Waypoint GrafNet allows for batch and network processing of multiple static GPS observation files. GrafNav/GrafNet StaticAs above without kinematic processing. GrafMovAdd-ons to the basic GrafNav/GrafNet module include an upgrade called GrafMov, which is our relative moving baseline processor that processes data from multiple antennas for heading determination. GrafNav LiteGrafNav Lite is a "scaled-down" version of GrafNav with accuracies aimed at the decimetre to sub-metre range. It is designed mainly for the GIS/mapping community. The principal differences between the two packages are that GrafNav Lite will process only L1, does not support ambiguity determination and is limited to processing at intervals no greater than 1 Hz.
Development KitsWin 32 Dynamic Link Libraries - GrafNav and RTKNav call DLL's for all of their high- precision processing. These DLL's can be used with available Development Kits to design your own value-added product.
