RACESENSE
RACESENSE
New technology solving old problems.
OCS DETECTION
Let the Atlas 2's Real-Time Differential GNSS call the start, and stop waiting for slow hails, inaccurate OCS calls, and countless general recalls. Competitors are notified milliseconds after the start if they're over or not, so it's easier than ever to restart and get racing.
PINGING IS THE PAST
Live broadcast pings are ending the parade. Each Atlas 2 receives the position of each end of the line, live. So, when anchored marks swing or the RC anchor line stretches, your DTL value will update automatically.
SYNCHRONIZED TIMING
The vast majority of error in start line judgement comes from timing errors: by using synchronized GPS time, every Atlas 2, as well as the time at which OCS determination is made, are synchronized to the millisecond.

OCS boats populate a list immediately after the start: no more waiting to hear from the pin boat or check the list of OCS participants.
FAQs
RaceSense is capable of making OCS calls accurate to less than 25 cm. This performance is the result of many optimizations across the entire RaceSense system, including the use of Real-Time Differential GNSS.
If you're interested in increased accuracy, the Atlas HALO RTK brings unprecedented 1 cm accuracy to the water.
An Atlas 2 or Atlas Edge instrument.
Yes! Select RaceSense events will have rental units available. That said, we think the Atlas 2 is the best sailing instrument on the water. Whether you’re sailing a traditional regatta, a RaceSense event, or just out for fun, nothing else comes close!
The Atlas 2 has state-of-the-art L1+L5 25 Hz GNSS. Working in combination with other sensors in the Atlas, the dual-band GNSS provides unmatched accuracy on the water.
RaceSense takes this even further, utilizing Real-Time Differential GNSS (RTDGNSS), seamlessly delivering correction data from a base station to each Atlas on the race course. This technique is closely related to the RTK GPS used by the America's Cup and SailGP, and available with the upcoming Atlas HALO RTK.
We designed RaceSense to be easy to use, for both sailors and organizers. Race committee will install an Atlas 2 on each end of the starting line, to measure and broadcast the live position of the line to the fleet. A tablet running the Vakaros Race Control app onboard race committee allows the PRO to run starts, view OCS boats, start race timers, and more.
RaceSense is designed for fleets of over 100 boats. If you’re running a large event, please get in touch to discuss how we can best support you.
We've run multiple events with over 100 boats, check out a recap of one here: Melges 15 Winter Series - 109 boats on one line!
When you arrive at a RaceSense event, you’ll bring your Atlas 2 or Atlas Edge to check-in or measurement on the first day. An event volunteer will scan your device, make sure the software is up-to-date, and link it with your registration. From there, all you have to do is remember to turn the instrument on, and RaceSense will do the rest!
RaceSense only works with the Atlas 2 and Atlas Edge. In fact, the Atlas 2 was designed from the ground up for RaceSense and carries special hardware just to support it. RaceSense requires accuracy beyond what other instruments are capable of.
RaceSense uses the shape of the boat to make OCS calls, and will call any part of the hull over the line no matter which direction you're sailing. This is made possible by the combination of the highly accurate magnetic compass and L1+L5 GNSS inside the Atlas 2--the system knows where the boat is and how it's oriented to the line.
We recommend being #AtlasEquipped everywhere you go. Additionally, at most RaceSense events, race committee will have a few spare units available should you misplace yours.
Yes! RaceSense offers support for multiple fleet. So, if you've got a few starts on the same course, RaceSense can still simplify your day. Simply toggle between fleets in the Race Control app and apply different courses, start times, and race instructions for each fleet.
