Helix Technologies Ltd. has been awarded a significant contract by the European Space Agency (ESA) to develop its next-generation GNSS antenna — a multi-frequency antenna optimized for the advanced Galileo E1 Alt-BOC and wide-band E5 Alt-BOC waveforms for use in driverless cars. The antenna, to be developed under the ESA’s Navigation Innovation and Support Programme (NAVISP), will provide enhanced performance due to its dielectric, multi-filar construction. It will also be optimized to take maximum advantage of the Galileo E5 Alt-BOC waveform, which enables significantly improved measurement accuracy, precision and multipath suppression over conventional GNSS signals. Learn more about the Helix Technologies antenna in our February issue article here. “In order to achieve the 10-centimeter accuracy that is required for autonomous vehicle lane-level positioning within challenging urban multi-path propagation conditions, there is a need both for a significant improvement in current GNSS antenna performance and to fully exploit the advanced Alt-BOC waveforms transmitted by Galileo,” said John Yates, managing director of Helix Technologies. The GNSS antenna, which will also be capable of optimized operation with the GPS L1 and L5 M BOC signals, is aimed at the automotive and consumer markets, and the company is targeting the third quarter of this year for the manufacture of prototypes. Independent testing and evaluation of the vehicle-mounted antenna performance will be conducted in the challenging multipath environments of the high-rise financial districts of the cities of London and Shanghai.
