ArrayNav is an innovative GNSS solution that applies multiple antennas to significantly improve signal sensitivity and accuracy. This advanced technology is an adaptation from the communication sector’s use of MIMO, tailored to address GNSS challenges like multipath errors and potential signal jamming. By employing a diversified antenna setup, ArrayNav enhances signal gain and diversity, achieving higher accuracy, especially in environments prone to signal degradation such as urban canyons.
The multi-antenna approach allows for distinct identification and suppression of interfering signals, including those used for spoofing or jamming, by analyzing their unique signatures. The system effectively places null signals in the direction of such disturbances, maintaining the reliability and precision of positioning data. This makes ArrayNav particularly beneficial for applications reliant on sub-meter accuracy and quick acquisition.
ArrayNav’s patented capabilities ensure robust GNSS performance, even in constrained environments, by boosting channel gain by 6 to 18 dB. This gain significantly improves operational efficacy in various applications, from automotive advanced driver-assist systems (ADAS) to personal navigation devices, ensuring dependable operation no matter the surroundings.
