Real-time Kinematic (RTK) GNSS positioning is a specific type of differential GNSS (DGNSS), which combines carrier-phase measurements with real-time correction data from a reference station to measure positions with an accuracy of 1 cm.
RTK is not a new technology, but recent advancements have significantly reduced the cost and complexity of integrating this measurement technique into the RaceSense system.
No -- RaceSense RTK is a new performance tier, designed to provide an option for classes and events who need more accuracy than the 25 cm provided by standard RaceSense. HALO is designed so that a class could choose to make use of it at certain events, like a World Championship, while continuing to use standard RaceSense for lower-tier competition.
RaceSense utilizes a highly reliable, fault-tolerant mesh network for all race management communication on the water. This ensures RaceSense can provide accurate and reliable race management anywhere in the world.
RaceSense specifically avoids use of cellular and other 3rd party networks for critical race management functions. On-the-water, these networks frequently have coverage gaps, high latency, and other challenges. We view RaceSense as a mission critical system, and consider these to be unacceptable risks.
Yes! In fact, RaceSense was inspired by and closely modeled on the America’s Cup LiveLine system, first used for the 2013 Cup in San Francisco, and later adopted by SailGP. RaceSense RTK completes this evolution, delivering accuracy comparable to that provided by these Grand Prix systems, for a fraction of the cost.
RaceSense RTK supports two different sources of correction data: commercial correction services, and user operated base stations. Each option has advantages and disadvantages, and we can work with you to determine the best choice for your event. Where required, both solutions can be used to provide an added layer of redundancy.
Yes, while we are striving to make the entire RaceSense system as affordable as possible, utilizing RTK technology does add additional cost to an event.

We work with each class and event organizer to define the requirements for installing Atlas HALO RTK receivers on every boat. For one-design fleets, this is typically a uniform location for each boat in the fleet.
To achieve maximum performance, HALO receivers need to be mounted with clear visibility of the sky, often near the transom. Receivers must be located on each boat with centimeter accuracy during the installation and measurement process.
For every new class of boat, our team starts by requesting a hull drawing from the manufacturer or class, which is used to program the hull shape into RaceSense. Then, the location of the HALO receiver relative to that shape is measured, allowing HALO to precisely determine the location of each part of the hull for all race management determinations.
For mixed, non one-design fleets, distinct hull shapes can be supported for each boat.
Yes, HALO is compatible with both the Atlas 2 and Atlas Edge instruments.
Yes, HALO can operate in a standalone capacity, including OCS notification via the LED ring.
