FUNCTIONAL DESCRIPTION 1.1. OVERVIEW The BE-252Q GNSS module is a high-performance satellite positioning module that provides superior sensitivity and acquisition time for all L1 GNSS systems. The extremely low power consumption of < 15 milliwatts in continuous tracking mode enables all battery-powered devices such as asset trackers to have strong endurance without sacrificing GNSS performance. The BE-252Q supports simultaneous reception of four GNSS (GPS, GLONASS, Galileo and BeiDou). The high number of visible satellites allows the receiver to select the best signal to maximize position availability, especially in challenging conditions such as deep canyons in cities. BE-252Q (Super Signal) technology provides excellent RF sensitivity and can improve dynamic position accuracy by up to 25% with small antennas or non-line-of-sight scenarios. BE-252Q detects jamming and spoofing events and reports them to the host so that the system can react to such events. Advanced filtering algorithms mitigate the effects of RF interference and interference, allowing the product to operate as intended. 1.2.
