ArrayNav represents a significant leap forward in navigation technology through the implementation of multiple antennas which greatly enhances GNSS performance. With its capability to recognize and eliminate multipath signals or those intended for jamming or spoofing, ArrayNav ensures a high degree of accuracy and reliability in diverse environments. Utilizing four antennas along with specialized firmware, ArrayNav can place null signals in the direction of unwanted interference, thus preserving the integrity of GNSS operations. This setup not only delivers a commendable 6-18dB gain in sensitivity but also ensures sub-meter accuracy and faster acquisition times when acquiring satellite data. ArrayNav is ideal for urban canyons and complex terrains where signal integrity is often compromised by reflections and multipath. As a patented solution from EtherWhere, it efficiently remedies poor GNSS performance issues associated with interference, making it an invaluable asset in high-reliability navigation systems. Moreover, the system provides substantial improvements in sensitivity, allowing for robust navigation not just in clear open skies but also in challenging urban landscapes. Through this additive capability, ArrayNav promotes enhanced vehicular ADAS applications, boosting overall system performance and achieving higher safety standards.
