GLOBAL COORDINATE NETWORKS & HIGH-PRECISION REFERENCE SYSTEMS
Introduction to
Earth-Curvature
Corrected Geodesy
At MD Sharma Company, we provide specialized DGPS Ground Survey solutions that establish highly accurate geodetic control networks for highways, railways, industrial facilities, and national-scale infrastructure projects.
Using multi-frequency GNSS receivers, DGPS rovers, and advanced geodetic processing, we connect local survey layouts to global coordinate systems, ensuring reliable positioning, precise elevation control, and engineering-grade accuracy.
OUR WORKFLOW
Our Technical
Geodetic
Workflow
Our geodetic engineers follow a scientific workflow to establish permanent reference networks, process GNSS observations, and deliver highly accurate global coordinate systems for engineering projects.
Monumentation & Permanent Benchmark Setting
Permanent concrete benchmarks are strategically installed to create stable reference points that remain fixed for the entire project lifecycle.
Static GNSS Data Acquisition
Long-duration observations using multi-frequency GNSS receivers collect high-precision satellite data while minimizing atmospheric and orbital errors.
Baseline Processing & Network Adjustment
Advanced geodetic software processes GNSS baselines and performs least-squares adjustments, linking project control points to national and global coordinate systems.
Orthometric Height Calibration
Geoid models and precision leveling convert ellipsoidal GNSS heights into accurate Mean Sea Level (MSL) elevations for reliable engineering and drainage design.
