Designed for GPS reference stations and networks, the V2.1.0 update for Spider software features an enhanced user interface with consistent map views supporting now-loadable background maps and graphical, continuous raw-data status view. The Spider update supports the company's GMX902 monitoring GPS receiver. Both real-time positioning and post-processing (to monitor slow moving objects) support data rates to 20 Hz. Leica has also introduced SpiderWEB software for Internet access to GPS reference-station data. The software can be used for single or multiple stations.
