Product Description
The UBX-M10050-KB chip is part of the u-blox M10 standard precision GNSS platform, providing exceptional sensitivity and acquisition times for all L1 GNSS systems. Its extremely low power consumption of <15 mW in continuous tracking mode allows for great power autonomy in battery-operated devices, such as asset trackers, without compromising on GNSS performance.
UBX-M10050-KB supports concurrent reception of four GNSS constellations (GPS, GLONASS, Galileo, and BeiDou). The high number of visible satellites enables the receiver to select the best signals, maximizing position availability, particularly under challenging conditions like deep urban canyons.
u-blox Super-S (Super-Signal) technology offers great RF sensitivity and can improve dynamic position accuracy by up to 25% with small antennas or in a non-line-of-sight scenario.
The chip detects jamming and spoofing events and reports them to the host, allowing the system to react. Advanced filtering algorithms mitigate the impact of RF interference and jamming, ensuring the product operates as intended. UBX-M10050-KB chips are qualified according to AEC-Q100, manufactured in IATF 16949 certified sites, and are fully tested on a system level.
