GPS/GNSS Surveys
GPS/GNSS surveying uses satellite positioning to establish precise, centimeter-accurate coordinates for control points, boundaries, and mapping data. Axis Geo-System Consultants runs RTK GNSS survey campaigns as the accuracy backbone for almost every other survey service we offer.
What It Involves
Using Real-Time Kinematic (RTK) GNSS receivers, we establish survey control networks and capture coordinate data with centimeter-level accuracy in real time. This underpins boundary surveys, topographic mapping, construction setting-out, and any project requiring geodetically accurate positioning.
Our Process
- 1Base station setup or connection to a reference network
- 2Control point establishment and verification
- 3RTK data capture across the site
- 4Post-processing and coordinate computation
- 5Delivery of accurate positional data for downstream use
Deliverables
- Control point coordinate schedules
- Georeferenced positional data
- Accuracy/quality assurance reports
Ideal For
- Any project needing survey-grade control points
- Boundary, topographic, and engineering survey campaigns
- Infrastructure and utility mapping projects
Frequently Asked Questions
What is the difference between GPS and RTK GNSS?
Standard GPS gives metre-level accuracy, sufficient for navigation. RTK GNSS uses a base-and-rover correction technique to achieve centimeter-level accuracy in real time, which is required for legal boundary, engineering, and construction surveys.
Why does every survey start with GNSS control?
Accurate control points anchor all subsequent survey work, from cadastral beacons to construction setting-out, to a single, verifiable coordinate system, ensuring consistency and legal defensibility of the final survey.
