Abstract
The study is focused on transmitting GPS observed data via the internet for near real-time post-processing solution. It exploits possible and available technology in integrating the basic concept of real-time GPS survey and post-processing technique to achieve a near real-time post-processing result. This was achieved by exploring the internet as a means of communication and transmission of GPS data for a near realtime post- processing solution. The base and rover stations were equipped with wireless mobile internet modems and portable mobile computer systems to provide the internet accessibility required for online transfer of downloaded observed GPS data in near real time. The research work with a view to saving the time required for post-processing of GPS data, process the observed base and rover data as fast as possible on-site as soon as the reference station data is received. This allow for check and correction of any observed error or anomaly on site. Based on the evaluated methodology, the positions of some points were determined. An independent web interface was also designed and tested using PHP (Hypertext Pre -Processor, a server side HTML scripting/programming language) for practical assessment and validation of the concept.
