GPS surveying differs from other GPS takes advantage of during the equipment and methods utilised. Static GPS works by using two receivers positioned in situation for a considerable length of time. The prolonged span of time allows the receiver Assess measurements as the satellites orbit. The changes given that the satellites orbit also present the measurement network with nicely conditioned geometry. This creates an accurate baseline which might be around 20 km very long. RTK surveying employs a single static antenna and one roving antenna.
Surveyors keep away from these mistakes by calibrating their equipment, working with dependable approaches, and by great structure in their reference network. Repeated measurements may be averaged and any outlier measurements discarded.
