Leica GS20 Professional Data Mapper

GIS Data Collection Just Got Easier

The Mapping Tool of Tomorrow is Here Today

The GS20 Professional Data Mapper (PDM) combines the all-in-one simplicity of a recreational GPS handheld with the power and flexibility of a professional grade mapping system. Providing you with a turn-key GPS mapping solution, the GS20 PDM is a professional GPS receiver, antenna, and data collector, all in an ergonomic handheld.

With the GS20 PDM, powerful functionality doesn’t mean difficult to use. The menu-driven interface and graphical map display make it easy to learn so field crews can start collecting data right away. Add to this the wireless connectivity to PCs and accessories provided by Bluetooth™ technology, and you begin to understand what we mean when we say the GS20 PDM is the mapping tool of tomorrow.

• Triple Data Redundancy Bluetooth™ cable free, Serial Cable, and Compact Flash downloads ensure you will never be without your data
• Power Page Functionality Multi-tasking capabilities of up to 6 simultaneous applications means not wasting time opening and closing windows
• Replaceable Batteries Your workday won't be constrained by the life of your battery
• Cellular Style Keypad Familiar Alpha/Numeric entry as easy as dialing a number or text messaging
• Rugged Housing and Connectors Equipment that can stand as much punishment as your field crew
• The GS20 is a GPS receiver, antenna and data collector, all in an ergonomic handheld package. The high-resolution high-contrast screen is easily readable under any outdoor conditions. A removable Lithium-Ion battery provides all-day runtime, and can be easily swapped with a charged battery in the field.
• The GS20 is the first GPS handheld unit that uses Bluetooth™ wireless communication with proven DGPS correction technologies to achieve sub-meter accuracy without a backpack. For data collection in harsh environments like dense foliage or urban canyons, an optional high-precision kit is available with an external survey-grade antenna.
• The menu-driven interface and graphical map display make the GS20 remarkably easy to learn. The unit is field-ready with very little setup required. Inexperienced users can take a unit to the field and start collecting data right away. The innovative Power Page functionality provides multi-tasking capability, permitting the user to switch rapidly between selected application menus.
• The GS20 provides Bluetooth wireless connectivity PC's and Leica Geosystems’ Wireless Real-Time Corrections Systems (WoRCS). The WoRCS package includes a belt-mounted Bluetooth communications hub, smart power supply and differential correction receiver providing everything needed for real-time sub-meter DGPS data collection.
