A Differential Global Positioning System (DGPS) Operator is responsible for conducting high-precision, centimeter-level, land surveying and geospatial data collection using satellite-based systems, primarily for infrastructure projects. They bridge the gap between initial site planning and actual construction by providing accurate coordinates for land, highways, metro systems, and mining sites. [1, 2, 3, 4]
Here are the key jobs and responsibilities of a DGPS Operator based on current job postings:
1. Field Survey Operations [1]
High-Precision Data Collection: Conducting topographical, boundary, and route surveys for large-scale infrastructure projects (metro lines, highways, transmission lines, urban development).
Establish Control Points: Setting up, maintaining, and verifying permanent benchmarks, Temporary Bench Marks (TBM), and traverse control points on site.
Setting Out & Layout: Marking plot boundaries, road alignments, and structural foundations as per design blueprints.
Independent Field Work: Handling and setting up DGPS equipment (base station and rover), GPR (Ground Penetrating Radar), and Total Station, often working independently in outdoor environments. [1, 2, 3, 4, 5]
2. Data Management & Processing
Data Extraction & Interpretation: Downloading data from DGPS instruments and processing it into usable survey data.
Drafting & Mapping: Using CAD software (AutoCAD, Civil 3D) or mapping software (Surfer, Global Mapper) to prepare contour maps, detailed site plans, and 3D elevation models.
As-Built Documentation: Updating and creating "as-built" drawings and survey reports for project documentation. [1, 2, 3, 4]
3. Equipment Management & Safety
Calibration & Maintenance: Ensuring DGPS units, total stations, and auto-levels are accurate and calibrated for high-precision tasks.
Troubleshooting: Troubleshooting field instruments to ensure minimal downtime.
Safety Compliance: Adhering to site safety protocols and working safely in challenging terrain. [1, 2, 3]
4. Coordination & Reporting
Liaison: Working with survey managers, civil engineers, and contractors to ensure the alignment of field data with design plans.
Reporting: Submitting daily/weekly field survey reports and inventory logs of instruments. [1, 2, 3]
Requirement : Bike is Mandatory.
