The improvements can be seen graphically too by comparing the following graphs. The first graph shows the new velocity accuracy using the gx processing algorithm.
This change is the first step in a series of major improvements to the GPS processing algorithms in the RT products. It is a result of 2 years of research work at OxTS into GPS processing. In the future we will be adding differential corrections to the gx processing and we will be working on our new ix processing algorithms, which will be a benefit in urban conditions.
More details about the new gx processing algorithm are available in our technical note. Download it here..
