DGPS Surveys

DGPS Surveys: Differential Global Positioning System augments the traditional Global Positioning System to provide enhanced location accuracy, from the 15-meter nominal GPS accuracy to about 10 cm in case of the best implementations.

However, at Precision Surveys we use Differential global positioning equipment to achieve precise positioning of less than 2mm to 5mm +or – in all the three axis & the positioning is on a global scale. We have proven capabilities to conduct DGPS Surveys for a range of geo-referencing activities for large scale urban development, irrigation, highway, railway projects, photogrammetric & lidar projects, etc. we also provide geo-tagged, Latitude, Longitude & MSL certificates for various real estate developments in formats as required by the competent authorities like the Airport authority of India.

We have static/rapid static & kinematic GPS receivers & latest processing software’s.

DGPS Surveys: Precise and Accurate Measurements for Your Projects

DGPS, or Differential Global Positioning System, is a surveying technique that uses a combination of GPS technology and ground-based reference stations to provide highly accurate measurements. This method is often used in construction, engineering, and mapping projects where precision is crucial.

The basic principle of DGPS is to use a GPS receiver on the survey equipment to collect data, and then compare it to the data from a nearby reference station. The reference station is a fixed location that has a known position and is equipped with a GPS receiver. By comparing the data from the survey equipment to the reference station, any errors in the GPS signal can be corrected, resulting in much more accurate measurements.

One of the main advantages of DGPS is its ability to provide sub-meter accuracy, even in areas with poor GPS signal. This is especially useful in urban areas where tall buildings and other structures can cause interference with the GPS signal. Additionally, DGPS can be used in a wide range of environments, including marine and terrestrial applications.

DGPS is also highly versatile and can be used in a variety of applications, including:

Construction: DGPS is often used in construction projects to ensure that buildings and other structures are built to the correct specifications. This can include measuring the position of foundation piles, checking the alignment of steel structures, and ensuring that the building is level.
Engineering: DGPS is also used in engineering projects to ensure that roads, bridges, and other structures are built to the correct specifications. This can include measuring the position of road markers, checking the alignment of bridges, and ensuring that the road or bridge is level.
Mapping: DGPS is also used in mapping projects to create highly accurate maps. This can include creating maps of land, roads, buildings, and other structures.

Overall, DGPS Surveys are a precise and accurate method for measuring and mapping projects, where precision is an essential requirement. With its sub-meter accuracy and versatility, DGPS is a powerful tool for any project that requires precise and accurate measurements. If you're looking for a reliable and efficient way to measure your projects, DGPS Surveys is an excellent choice.
