Leica upgraded its GS50+ line of GPS receivers for GIS mapping, capable of acquiring data with accuracy to the centimeter level. The receiver is developed specifically for GIS mapping featuring a GIS application program. The GS50+ is capable of post processing and real-time centimeter data collection. It can use RTCM radios or cell phones for real-time DGPS communications, and it's capable of long-range RTK out to nearly 22 miles (35 kilometers). Leica says it is the only GPS receiver that can be upgraded from L1 single-frequency, sub-meter mapping system to a high-precision, dual-frequency system using the same hardware. Estimated price: $18,110.
