Global Positioning System Services

DG&A offers the latest expertise and technology for its GLOBAL POSITIONING SYSTEM (GPS) SERVICES. We use the NAVSTAR navigational satellite network to determine the relative position of survey points to an extremely high degree of precision. Geodetic coordinates (latitude and longitude) are also determined. GPS is extremely accurate, versatile and is also the quickest method of locating remote points. Projects which would take days with conventional methods can usually be completed within a few hours.


Our surveyors collect satellite data by utilizing our Real Time Kinematic Dual Frequency receivers at the survey site. These state-of-the-art, weatherproof units are capable of producing real-time, 3-dimensional data.

Surveyors can quickly reduce field data and coordinate values on-site, utilizing a complete post-processing software system. DG&A associates have been factory trained in GPS procedures and are well qualified to perform accurate surveys in a very timely manner.

Fewer man-hours are required to perform surveys, often reducing costs, and the highly precise methodology of GPS reduces the possibilities of error associated with traditional techniques.
