Handheld GPS Receivers: Variables Affecting Accuracy and Implications for Geocaching

Here's the final instalment... After researching how GPSrs work, designing an experiment to assess which variable most affects the accuracy of coordinates calculated by a handheld GPSr and analyzing almost 2000 observations taken under a wide range of conditions, it was time to consider the implications of the results when it comes geocaching. Here's a …

Handheld GPS Receivers: Results From Experiment to Assess Which Variable Most Affects Coordinates Accuracy

This is the third instalment in a series about our Oldest GeoKid's grade 5 science fair project, undertaken when we were still relatively new to geocaching and had a keen interest in better understanding the optimal conditions for taking accurate coordinates for our geocache hides. Part 1 outlined the many variables he planned to evaluate. …
