DGPS stands for Differential GPS, and is the process of applying corrections to a normal GPS signal to improve accuracy. A standard consumer GPS or smart watch has an accuracy of 5 metres or worse. This accuracy can be improved by systems in Australia where real-time errors are logged within a network of accurate coordinate stations. The error corrections are applied simultaneously to your own GPS receiver and are carried by internet log-in or by augmented satellite messages such as OmniSTAR/Trimble RTX/Hemisphere Atlas which do not rely on internet or 4G/5G coverage. Access to DGPS corrections is by periodic subscription and are applied in real-time while you are using the equipment in the field. The better accuracies work with and enhance any type of mapping or computer application, just like connection to a normal GPS unit.
DGPS systems provide sub-metre (50-70cm), or deci-metre (10-15cm) real-time accuracies. The position results are shown and applied in real-time on your device. We specialise in Hemisphere, Trimble, and OmniSTAR systems for all budgets.
If you need a DGPS system for only a short period or project, you may wish to take advantage of our hire rates. We have daily, weekly, and monthly hire rates to suit any project length. You choose if you want decimetre, submeter, or standard GPS accuracy.
