Abstract

As found in remote areas of Australia is limited or no availability survey control infrastructure holding datum coordinate values such as Map Grid Australia (MGA) and Australian Height Datum (AHD). Surveyors utilise such datum’s to connect a consistent coordinate reference frame for projects and to maintain a regular project position. In areas of unknown coordinates, GPS observations can be made and data can be sent to a free online processing service called AUSPOS. The subject project topic has come about from observing there are discrepancies in values that have been processed by AUSPOS from use in the past. Inconsistency is common in vertical height values and has triggered an investigation into the reliability of the processed data. The project investigates the reliability of coordinate data reduced by the AUSLIG Online GPS Processing Service “AUSPOS”, specifically in relation to height. Testing has been carried out by observing GPS data for a number of permanent survey marks that have known coordinates and height. Observed data was submitted to AUSPOS and processed coordinates determined. Analysis was then made in relation to the differences obtained in coordinate values and time frames observed and conclusions made with respect to results obtained
