In the continuously developing GIS market, forestry applications and, in general, no-geodetic users pose more demanding requirements. Customers are primarily asking for better accuracy: in network management applications (water distribution, telecommunications or electricity, etc) sub-meter accuracy is just not enough. Extended position availability is also becoming a strong requirement: being unable to run GIS projects in obstructed areas because of a lack of reliable positions due to adverse reception conditions is simply unacceptable. In parallel, as the number of specific GIS applications increases, customers are asking for more processing power, higher-quality screens and truly \"Handheld-operated\" receivers.
