The fleet sailing tracking app eStela allows you to broadcast in real time your position during the race.

1. - Enable the GPS location of the mobile.
2. - Enter your key assigned by your club.
3. - Start to broadcast.

eStela start sending your position automatically and stops when the competition is over. During the race or after its completion you'll see it from the website of estela.co

Now eStela support Bluetooth LE instruments (CUPS 4.0 and NMEA Connect) from calypsoinstruments.com

Note: As other sailing tracker applications eStela uses GPS intensively even when running in background which affects the battery life. It is highly recommended the continued use of the charger during all the race.
