With the right equipment and under the right conditions, one can achieve decimeter, centimeter or even millimeter level positioning. Such processing requires data to be collected from two GPS receivers, one of which be at a known position.<br /> It process data within seconds. PPro2 is extremely easy to use. Just specify the base and rover GPS observation files and click on the &quot;Process Job&quot; button. Advanced users may also specify additional parameters for processing.<br /> With PPro2&#039;s robust modeling of the Ionosphere and Troposphere it is possible to process baselines of several hundred kilometers in length, especialy when using dual frequency equipment. SP3 precise orbit support virtualy eliminates the effect of broadcast orbital errors on longer baselines. Ionosphere-free L0 float solutions allow for accuracies of a few decimeters with tens of minutes of data over a thousand kilometers. Fixed solutions is sometimes possible with observations spanning several hours over a baseline several hundred kilometers in length.";
