Difference Between GPS and DGPS Survey – Why DGPS Is Preferred in Gujarat Projects

In Gujarat’s rapidly developing infrastructure and real estate sectors, accuracy is the foundation of success. While GPS (Global Positioning System) has been used for years in mapping, DGPS (Differential Global Positioning System) is now the preferred method for professional land surveys.

🌍 Understanding the Basics

• GPS provides location coordinates using satellites but can have errors of several meters.

• DGPS, on the other hand, uses a base station and a rover to correct signal errors, offering accuracy up to 2–5 cm.

⚙️ Why DGPS Is Better for Surveying

1. Higher Accuracy – Ideal for boundary marking, road alignment, and government projects.

2. Real-Time Corrections – Ensures consistent precision in large open sites.

3. Better Data Quality – Reduces post-processing time and improves mapping results.

4. Used in Complex Projects – DGPS is widely used in highways, canals, and township layouts.
