A CORS is a static, survey-grade GPS receiver which is permanently positioned at a known geographic location and collects data 24 hours a day, seven days a week. Coordinated by the National Geodetic Survey (NGS) of the National Oceanic and Atmospheric Administration (NOAA), CORS sites provide Global Navigation Satellite System (GNSS) measurements in support of 3-dimensional positioning activities.
CORS data can be used for Real-Time Kinematic (RTK) applications, meaning that the station provides continuous correction data to roving GPS receivers with internet accessible capabilities.
The benefit of a CORS site or network is the ability to provide accurate, repeatable position data free of charge permitting users to return to the exact same locations over time. Data collected from CORS sites has a wide array of uses. For example, CORS data can be used for monitoring coastal subsidence, surveying, determining the amount of precipitable water vapor in the atmosphere, recording and locating utility lines, and machine guidance for construction and precision agriculture. Users include local, state, and federal government, transportation, construction, emergency management, homeland security, surveyors, education, natural resource, and agriculture.
Each year the American Society of Agricultural and Biological Engineers (ASABE) selects a topic for their Distinguished Lecture Series. For 2009, the topic was ‘Automatic Vehicle Guidance’ which was presented by Drs. Arthur Lange and... more
