In October 2010, aseries of tests have been conducted to validate the X90 GPSposition accuracy and repeatability using both standard single base station andnetwork RTK solution services from ASG-EUPOS(NAWGEO: FKP2.3, VRS 2.3 and VRS3.1) under various environments.
"In accordance to our ISO 9001 quality system, we have decided to handover the evaluation of our X90 GPS receiver to an independent and recognized European organization. The results show a xy/h standard deviation always lower than 12 mm, validating the field results obtained every day by our customers in more than 50 countries." said George Zhao, CEO of CHC. "This evaluation confirms that our goal to design and manufactureaccurate and reliable GNSS solutions is achieved. CHC is more than ever the first choicefor demanding yet cost conscious surveyors."
CHC designs, manufactures and markets a wide range of professional GPS/GNSS solutions in various markets such as land surveying, civil engineering, utilities, deformation monitoring...
