GNSS Surveys
Spatial Data Services harnesses the power of GNSS (Global Navigation Satellite System) technology, employing both base and rover systems to establish remote site survey control, conduct topographic surveys, and facilitate drone PPK (Post-Processed Kinematic) surveys with unparalleled precision and efficiency.
With the GNSS base station serving as a reference point, our rover unit accurately captures real-time positioning data across vast and often challenging terrains, ensuring reliable survey control even in remote or inaccessible areas. This robust setup enables us to perform comprehensive topographic surveys, capturing detailed elevation data and mapping terrain features with exceptional accuracy.
Additionally, integrating GNSS technology into our drone PPK surveys enhances the georeferencing of aerial imagery, enabling precise mapping and analysis of large-scale areas with minimal ground control points. By leveraging GNSS base and rover systems, Spatial Data Services delivers reliable and high-quality survey data, empowering clients with valuable insights for informed decision-making in various industries and applications.

Benjamin Franklin's once said: “By failing to plan, you are preparing to fail”.
The use of RTK GNSS is required on remote projects. The RTK signal required to operate machinery relies on both GNSS satellites and signals containing corrections from a base station and/or repeater. These signals containing corrections can be blocked by terrain; which then causes downtime of machinery. The location of base stations and repeaters therefor needs to be planned in advance to ensure RTK corrections reach GPS enabled machinery.
Above is a drawing of a GNSS analysis for gas fields in Central Queensland. Each green square is a gas field of 10km x 10km. The different colors represent signal from each base or repeater. In an ideal world we should see a colored circle for each base or repeater; however instead we see blotching /signal shadowing caused terrain. Without pre-planning of GNSS location a contractor may require up to 20 mobile base stations to cover the area on the drawing. With pre-planning only six permanent base stations are required saving the contractor over 1.5 million dollars of equipment and the daily setup cost of each temporary base station.
Spatial Data Services can pre-plan sites to optimize GNSS infrastructure. This optimization reduces survey costs and maximizes machine productivity. This pre-planning technique was developed by the owner of Spatial Data Services for a large remote inland project, in Australia.
