Some research suggests that GPS services are accurate to +/- 10 metres for 95% of requests.
However, there are many anecdotal reports that this is not the case. An organisation called Thinknear has published three quarterly infographics suggesting that in practice, LBS are highly inaccurate, see http://www.thinknear.com/library/research/ , with evidence that 54% of reported locations are in error by more than 1000 metres.
This project is a leading edge research project which has collected one of the largest datasets of the accuracy of Assisted GPS (A-GPS) based location services from the research of 14 final year undergraduate students undertaken for their BSc Dissertation Projects.
The following are the eight best Dissertation reports evaluating a range of different perspectives and consequences for the levels of accuracy under a range of different conditions.
The results of the students’ research have been published at a range of different conferences during 2015. Corah, Patel and Horecny were joint co-authors with me for a paper presented at the SAS Global Forum in April 2015 in Dallas, Texas, see SAS Mapping functionality to measure and present the Veracity of Location Data
The following eight reports all achieved a mark equivalent to a first class honours level, that is a mark of 70% or higher.
