4. Context GPS accuracy claim: 95% of all fixes to be <=10m Thinknear identify the fact that 46% of reported locations are accurate <= 1000m (Q1 2015 Location Score report) 10% error > 100,000m (60 miles) My students’ research indicates (2420 data points) 85% are accurate to <= 25m 2.5% are >= 500m Outliers 1km to 80km 4Richard J Self - University of Derby
