DGPS stands for Dual frequency Global positioning system. This Instrument was basically designed for finding the actual ground positions in terms of Latitude and longitude. In earlier times when the technology was introduced, the aim was to serve all Defense requirements, like the design of missiles. The American defense department launched 24 satellites named NAVSTAR. These satellites are arranged in such a way that a minimum of 4 satellites is accessible to the tracking instruments. The GPS instruments track the positions of the satellites in terms of Almanac and other basic information. Further, these data are analyzed known as post processing to get the Location of the Point in terms of UTM (Universal Transverse Mercator) and Latitude and Longitude. The accuracy of the location depends on various factors like duration of observation, availability of satellites, obstructions in the vicinity, etc.… Later these instruments made through to the market for domestic use by the surveyors.

Use of DGPS for road/highway projects

Mejestic

In earlier times, the surveyors used the traditional method to find the bearings of a line by observing stars like the sun. Now the technology of DGPS is widely used to fix the points accurately to have a complete horizontal control with the WGS (World Grid System). These points ensure that further traverse legs are reckoned and closed with a pair of GPS points already established. Thereby surveyors are also confident of the open traverse conducted and a need to re-check the traverse is eliminated.

Google earth integration

With the google earth technology, we are even more confident of the surveyed loops and topographical features. As the interest developed with the UTM coordinates which are already available with the GPS technology, Integration with Google earth became much necessary to visualize the surveyed topographical features. On these lines several applications are developed to overlay the surveyed drawings into Google earth and back. One such application "KML Module" is developed by ESurveying softect which is a more convenient way for the interface. It easily transfers the drawings into Google earth and back to a drawing application with or without any modifications. It also facilitates the user to create drawings components like lines, polygons with the text to be created in Google earth and directly export to drawing applications without losing its Geo locations and UTM Projection.
