Red Bull Air Race Selects the VectorNav VN-300 for Onboard Telemetry
16 April 2018
VectorNav Technologies, a leading supplier of embedded inertial navigation systems is pleased to announce that Red Bull Air Race have selected the VectorNav VN-300 Dual Antenna GNSS-Aided Inertial Navigation System as the primary source of aircraft telemetry data for the Master Class raceplanes participating in the Red Bull Air Race World Championship. The inaugural event of the 2018 season in Abu Dhabi saw the VN-300 used for the first time in all 14 aircraft to provide real-time telemetry data used for judging, in-race simulation and virtual reality applications.
Created in 2003, the Red Bull Air Race World Championship has held more than 80 races around the globe. The Red Bull Air Race World Championship features the world’s best race pilots in a pure motorsport competition that combines speed, precision and skill. Using the fastest, most agile, lightweight racing planes, pilots hit speeds of 370 km/h while enduring forces of up to 10 G as they navigate a low-level slalom track marked by 25-meter-high, air-filled pylons. Pilots incur time penalties for hitting pylons, incorrectly passing through the Air Gates or only exceeding 10 G for more than 0.6 seconds, amongst some others.
Being an individual sport, spectators need a reference to see the difference between the pilots’ lines and speed through the racetrack. Red Bull Air Race Live TV utilizes an augmented reality (AR) solution known as the Ghost Plane to display the trajectory of the pilots’ runs for real-time comparison in the head-to-head rounds and the Final 4 that decides the winner of the race by time. The Ghost Plane is driven by the position, velocity and attitude data gathered during flight from the onboard Inertial Navigation System (INS).
Critical to the success of the Ghost Plane is the accuracy of the telemetry data, which given the high dynamics experienced during flight is extremely difficult to obtain. For example, as a plane races through a chicane and into a vertical turn maneuver GPS signals are lost and the INS needs to rely solely on the inertial sensors to accurately estimate the position and velocity until GPS is fixed again in level flight. Alvaro Navas, Sport Technical Manager for the Red Bull Air Race, says “We evaluated several different inertial navigation systems and struggled to find one that was able to perform in our dynamics. VectorNav’s VN-300 was the only product able to deliver the attitude, position and velocity data accuracy we require, and it did this out of the box, no customization was required. The sensor is really amazing!”
