GPS in COURSE MEASUREMENT for Road Races

In this series of pages we are collecting information to guide road race course measurers in using consumer type GPS units as ancilliary aids in the measurement of road race courses. These GPS units are not sufficiently accurate to replace the Calibrated Bicycle with a Jones Counter for accurate measurement, neverthelss they can be useful for specific secondary tasks such as: Reference point finding, and Mapping Courses.

To navigate back to this GPS index page click on the Garmin Etrex image (see right) which you will find on each page in this section of the website.

Testing the performance of the Garmin ETREX H (2009) :

• Overview
• Choice of GPS unit
• Repeatability of ETREX H marked waypoints - and their potential use to help identify reference points for distance marks.
• Modelling of GPS accuracy for distance measuring
• Experimental data for the measurement of the length of the Long Tow calibration course with GPS
• Repeatibility of GPS tracks for the Abingdon 4.5k loop
• Prediction of accuracy of GPS distance measurement for the Abingdon 4.5k loop
• Experimental data for the measurement of the length of the Abingdon 4.5k loop by GPS
• Rayleigh distribution
• Links

Testing the performance of the Samsung Note 10.1" tablet (2014):

• Logging Apps: GPS STOPWATCH vs GPSlogger
• Using GPS tagged Images in COURSE MEASUREMENT for Road Races

Runners use of GPS (the following pages need reformatting)

• Keevil 10k
• Run to the Beat Half Marathon
• Runners' with GPS think a course is short. Bike measurement, confirms what GPS traces suggest, the turn round is short. See Phil Holland's report.
