Unveiling the World of DGPS Survey Monitoring: My First Site Experience at Solar Power Project at GlaxoSmithKline Pharmaceutical Limited, Nasik Maharashtra 

In this blog, I am sharing my first site experience.

As technology advances, so does the field of surveying. The introduction of Differential Global Positioning System (DGPS) surveying has revolutionized the way we measure and map our world. Recently, I had the opportunity to dive into this fascinating field and experience the process of monitoring a DGPS survey firsthand. Join me as I recount my exciting journey and unveil the wonders of DGPS survey monitoring.

1. Setting the Stage

Upon arriving at the survey site, I was greeted by a team of experienced surveyors armed with high-tech equipment. They explained that DGPS surveying utilizes a network of ground-based reference stations and satellites to enhance the accuracy of GPS positioning. Unlike traditional GPS, DGPS corrects for signal distortions caused by factors such as atmospheric interference, ensuring precise measurements.

2. Understanding the Process

To begin, the surveyors established a reference station at a known location. This station acted as a control point, providing accurate positioning information that could be used to correct any errors in real-time measurements. The team meticulously set up the reference station, ensuring it was stable and protected from potential disturbances.

Next, the surveyors deployed several rovers—portable GPS receivers—throughout the survey area. These rovers were equipped with DGPS receivers capable of receiving correction signals from the reference station. The surveyors carefully placed the rovers at specific locations, marking them with precise coordinates and setting up continuous data collection.

3. Monitoring the Survey

Once the survey was underway, I observed the surveyors closely monitoring the data coming in from the rovers. They utilized software that displayed the real-time positions of the rovers in relation to the reference station. This allowed them to track deviations or inaccuracies and promptly make necessary adjustments.

Throughout the survey, the team frequently communicated with each other, exchanging information and ensuring that all data was collected accurately. They also used quality control measures, such as redundant measurements and cross-checking, to verify the reliability of the collected data.

4. Troubleshooting and Challenges

During my time at the survey site, I witnessed the surveyors tackling various challenges. They encountered signal interference due to nearby buildings and dense vegetation, causing momentary disruptions in the DGPS data stream. However, the team employed strategies such as adjusting the rover's position and using additional correction sources to mitigate these issues and maintain data accuracy.

Moreover, the surveyors emphasized the importance of continuous equipment calibration and maintenance to ensure optimal performance. They regularly checked for battery life, antenna alignment, and signal reception, promptly troubleshooting technical glitches.

5. Conclusion

My first site experience monitoring a DGPS survey was an eye-opening adventure into high-precision positioning and data collection. I gained a newfound appreciation for the complexity and meticulousness required in this field. DGPS survey monitoring showcased the fusion of cutting-edge technology and human expertise, resulting in accurate and reliable measurements.

As technology continues to evolve, DGPS surveying will likely play an even more significant role in various industries, including construction, engineering, and environmental monitoring. It can potentially transform how we map and understand our world.

I left the survey site with a sense of wonder and excitement, eager to explore further applications of DGPS surveying and witness the continued advancements in this field. If you ever have the chance to experience DGPS survey monitoring firsthand, I encourage you to seize the opportunity—it is truly a remarkable journey into the realm of precision measurement.
