Crescent receiver technology provides higher update rates, improved raw measurements, more memory, and greater processor capacity, creating an exceptionally robust and affordable DGPS solution. Its more accurate code phase measurement and superior multi-path rejection translates into an extremely accurate and stable receiver. In addition, the fast start up and reacquisition times allow users to power up and get right to work.

"The survey and GIS mapping markets are growing globally with the continuing demand for rugged GPS data collection devices," said Steven Koles, President and CEO of Hemisphere GPS.
