GPS surveying
Global Positioning System surveys are now more widely used in the utility surveying industry than ever.
The GPS system utilises a network of 24 orbiting satellites which continuously broadcast a microwave signal that our receiver/transmitter locks on to, giving accurate locations especially when able to triangulate with these satellites or use base stations. These positions can then be de-coded and exported into CAD applications.
We successfully use this equipment for accurate as-laid drawings and often use this to gain accurate GPS positions in a field environment or any open space to tie a survey into a clients GIS system.
The GPS system can also be linked with our utility location devices giving not only an accurate position of plant, but logging the GPS co-ordinate at the same time.
There are two methods of using the equipment. There is the Differential GPS which simply receives a signal from the satellites and records it which but the more accurate method of using the technology we find is to use base station (s) which send a radio signal to the receiver in the field giving accuracy within millimetres.
