Sortable List by each column
Auto Update: results and rank updated automatically every 10 sec
Track Download: cloud pictogram to download recorded GPX files of specific participants
Each device: GPS trackers same as our Tracking App - no additional timing hardware needed
Real-time Prediction of rank based on the average speed along the shadowtrack
Net Results: If GPS device passes a virtual split (geo fence) within 100 m distance from shadowtrack, time difference from 1st (normally "start") split is calculated
There are two ways to access the GPS result list:
Click the clock pictogram in search bar of tracking map
Use the unique URL
Spectators access GPS results directly in search bar of the tracking map through the timing link.
You also reach the result list through a unique URL.
With the download link you download the data from the timing table as a *.csv file.
More information about the *.csv file:
Prevent accidental Start and Finish reads
If participants wait before starting the race and their GPS device already sends locations within the "Start" geo fence, in that case GPS Timing might be triggered too early. The same szenario is possible with "Finish" detections in the finish area.
To prevent unintentional start- and finish detections just move the virtual split for "Start" 100 m along the shadowtrack (= 100 m behind real start area) and the "Finish" timekeeping 100 m against the shadowtrack (= 100 m before the real finish).
Ensure mapping from Start
For GPS timing and LiveRank the algorithm needs to be able to map the location of the real start area to the virtual "Start" on the shadowtrack. If the 1st location the algorithm receives from a device is closer to lap three then this device is mapped into lap 3 with the wrong distance on the shadowtrack.
We made a comparison of GPS timing against a professional timing solution during the 100km-Duathlon:
Results of GPS-Timing corresponding to data of GPS trackers
The comparison of our GPS timing solution against a timing system shows
GPS timing provides results with low budget and low effort, no additional hardware needed
Same sequence of the scoring with GPS timing and with professional timing solution

There for we set-up a shadowtrack with 60 laps and a geofence @ charging zone_in and @ charging zone_out for each lap, which means this event was running with 120 virtual splits. All information were provided through a live page https://live.ecograndprix.com/.
