NAVISP prototypes sophisticated Antennas to combat interference and to support high accuracy

In the past few months, several NAVISP activities came to a positive conclusion, proving the concept of new antenna technologies, and setting the foundations for innovative products and services to be delivered in the coming years.


LoCoMotive (NAVISP Element 1), looked into the potential advantages of Low-Cost GNSS Antenna Arrays for Improved Performance, Anti-Spoofing, Meaconing and Interference Mitigation for automotive applications, concluding with the test of a low grade antenna. Novel multi-antenna/correlator algorithms were tested in representative environments, confirming their added value for jamming and multipath mitigation and for robustness of the position solution.

Low-cost multi-frequency multi-constellation GNSS antenna for CubeSats (NAVISP Element 1), worked on the design, manufacture and qualification of a state-of-the-art wide band GNSS antenna. Designed in particular for CubeSat, without compromises on compactness and space environment qualification, it shows high stability in phase centre variation versus frequency and exceptionally constant group delay. The project paid the utmost attention to the effective electromagnetic properties of each material used in the antenna, and to the manufacturing precision. The antenna will flight soon on a Cubesat as part of a GNSS receiver for in-orbit demonstration of Precise Point Positioning.

VANTIGE-2 (NAVISP Element 2), the Navigation Interference resilient GNSS Enhancements project, defined the basis for a new beamforming antenna product, upgrading the RF front-end to utilise Direct RF sampling, and improving the performance of this anti-jam system, by  enhancing the beamforming algorithm implementation and significantly reducing the algorithm processing time, thus increasing the system's update rate.
