Leica Geosystems announced a new firmware release, Version 1.05, for the GS20 professional data mapper (PDM), featuring support for Wide Area Augmentation System (WAAS) and Hypertrak GPS tracking. Introduced in May 2003, the GS20 is the first GIS/GPS product to combine the accuracy of a sub-meter GIS mapping system, the ease of a handheld GPS receiver and the convenience of Bluetooth wireless connectivity. The addition of WAAS capability in the new firmware release permits GS20 users to get sub-meter accuracy in the field without the need for dedicated DGPS reference station networks. The Hypertrak capability provides extended GPS tracking even under extreme foliage cover and in urban canyons. Other new functions provided in Version 1.05 include additional NMEA output strings for outputting data to external devices, and a new capability for interfacing with the latest DISTO handheld laser rangefinder for gathering data from inaccessible locations. The GS20 firmware 1.05 will be available to customers — at no charge — in August 2003.
