The UBX‑G8020‑KT GNSS chip, based on the latest u‑blox 8 position engine, supports GPS/QZSS, GLONASS, and SBAS. With superior sensitivity and acquisition times it sets new standards for single constellation receivers.
UBX‑G8020‑KT chip is targeted for applications where small size, high performance, minimal power, and low system costs all are a must. With a dedicated mode for wrist worn applications, UBX‑G8020‑KT is a perfect choice for wearable devices.
UBX‑G8020‑KT features low power consumption and supports advanced Power Save Modes. It also provides message integrity protection, geofencing, spoofing detection, odometer, and data logging functionalities.
The UBX‑G8020‑KT is available in an industry standard QFN package. Featuring built‑in LNA, LDOs and DC/DC converter, and a small external BOM, the UBX‑G8020‑KT enables ultra‑small solutions with a footprint of only ~50 mm2. By supporting TCXOs or lower price oscillators, the UBX‑G8020‑KT further ensures a minimal Total‑Cost‑of‑Ownership.
UBX‑G8020‑KT was built with backward compatibility in mind, thus simplifying migration from existing u‑blox G7020‑KT designs.
With its rigorous quality and manufacturing standards (AEC‑Q100, ISO/TS 16949), UBX‑G8020‑KT meets the requirements for industrial and consumer applications.
