ArrayNav is an innovative GNSS solution that employs multiple antennas, enhancing sensitivity and accuracy to combat common issues like multipath interference and signal jamming. This technology is designed to increase the effectiveness of global positioning systems by using adaptive antenna systems, a concept borrowed from advanced wireless communications. ArrayNav provides up to 18dB gain in signal strength for fading channels and ensures robust performance even in complex environments like urban canyons. By identifying and nulling unwanted signals, it maintains the integrity of GNSS operations against spoofing and interference. This technology is vital for applications needing high precision under challenging signal conditions. With its sophisticated antenna diversity, ArrayNav is crafted to deliver sub-meter precision and swift signal acquisition. This makes it a valuable component for navigation in densely constructed urban landscapes or covered environments where satellite visibility might be obscured. ArrayNav's capability to handle multipath and interference issues effectively makes it a preferred choice for high-reliability navigation systems, contributing to both enhanced security and accuracy.
