The Mobile App (2 of 2)

A walkthrough of the GPS Benchmark mobile phone application (continued):
7) As data is collected, the app shows horizontal, vertical (if ground truth altitude is entered), and estimated horizontal accuracy error statistics that are continuously updated in real-time.  The red marker shows an average of the last X number of fixes (adjustable via Settings).

---------------------------------------------------------

10) You'll be asked if you want to email the results.  If yes, you'll be shown a list of apps you can choose to send the email.
8) When you've collected enough data, select "Stop Test" via the menu.








---------------------------------------------------------

11) Enter the destination email address to send the results, with data in zip file, to yourself or others for review (see Results for examples)
9) You will be shown a wait screen while the summary statistics (e.g., percentiles) are calculated.  This may be several minutes for large data sets (e.g., > 3600 samples), depending on the speed of your phone's CPU.




---------------------------------------------------------

12)  After closing the email app, the results are also shown on the screen for quick review.
