GPS Geodetic Survey is commonly used for:
- Establishing and measuring project control points (benchmarks)
- Determining the coordinates of land boundaries or key points
- Tying survey, drone, or LiDAR results to a specific coordinate system
- Mapping large areas and linear projects such as roads and networks
- Monitoring the movement or deformation of a point or structure
Its advantage is that measurements do not require line of sight between points, making it more efficient for large areas and long distances.
Scope of Work & Work Stages
- Survey Consultation & PlanningWe define the objectives, accuracy requirements, coordinate system to be used, and the number and distribution of points to be measured.
- Reconnaissance Survey & Point Site SelectionPoint locations are chosen to have open sky, be safe, and be easy to find again.
- Installation of Point Markers or MonumentsPoints are marked with stakes or monuments so they are durable and reusable.
- Field Satellite ObservationA geodetic receiver is set up at each point and observes satellite signals for a duration that matches the method and required accuracy.
- Data Processing (Post-Processing)Observation data is processed using specialized software to calculate the coordinates of each point.
- Adjustment & Accuracy CheckCalculation results are checked and adjusted to ensure the accuracy meets requirements.
- ReportingAll data, calculation results, and point descriptions are compiled into a report.

Integrated with Other CRN Services
PT Cipta Reka Nusantara handles surveys, design, engineering, and permitting within a single team. Data from this service is used directly in subsequent work, so there is no need for re-measurement and every project stage uses the same reference.
- Reference for all mapping: GPS geodetic control points serve as the framework for Topographic Survey, mapping with Drone, and Lidar so that all data is in a single coordinate system.
- Land boundaries and legality: accurate land boundary coordinates support the preparation of documents for Building Approval (PBG).
- Structural monitoring: repeated measurements at the same points help monitor movement or deformation, providing supporting data for Factory & Warehouse Structural Audit and Tower Strengthening.
- Technical planning: well-tied coordinates and elevations ensure that designs in Detail Engineering Design (DED) match actual positions in the field.
