GNSS Resurvey of a local Float SSM Network in the Bulong Area

Jake Martin

OBulong is an abandoned town approximately 42km East of the city of Kalgoorlie in Western Australia. Gold was first discovered in the Bulong area by a group of five prospectors in 1893. Upon the discovery, the town’s population grew to 620 by the year 1900. The town had a hospital, school, police station, telegraph station and post office. One of the prospectors responsible for discovering the future town was a surveyor named G. Hamilton. When the town was officially gazetted in 1895 Hamilton decided to name the town after a nearby spring the Traditional Landowners called, Bulong.

The aim of this project is to re-survey a small Standard Survey Mark (SSM) network in accordance with the current Landgate specifications south-east of Bulong that was last surveyed in February 1990. This network will be statically observed using Global Navigation Satellite Systems (GNSS) surveying technology.

The results obtained will be compared against those from the original survey in 1990. This extensive comparison will allow us to gain a better understanding as to how the Global Navigation Satellite Systems (GNSS) Surveying positional accuracies have improved over the last 30 years.
