UBX-G8020-KT 개요
A GNSS (Global Navigation Satellite System) chip is a fully integrated receiver subsystem that decodes positioning data from multiple satellite constellations and outputs time, velocity, and position fixes to a host processor. GNSS chips sit in the positioning IC category within RF & wireless semiconductor hierarchy, and they relieve host CPUs of the real-time signal processing burden required for satellite acquisition and tracking.
Key features include -166 dBm tracking sensitivity for indoor and wearable wearable scenarios, advanced jamming and spoofing detection for automotive and industrial robustness, and pin-compatibility with the UBX-G7020-KT and UBX-M8030 families, allowing seamless migration across product generations. The chip supports either TCXO or lower-cost crystal oscillators, giving designers flexibility between premium and economy BOMs.
Internally, the UBX-G8020-KT combines a low-IF RF receiver, a dedicated GNSS baseband, and an integrated power management unit. The on-chip LNA reduces external component count and improves noise figure, while the integrated DC/DC converter and LDOs minimize external power-tree complexity. This SoC approach contrasts with discrete GNSS receiver architectures that require external RF front-end and PMIC.
Typical applications include wearable fitness trackers, asset trackers, automotive telematics, and industrial IoT positioning modules. Its standard professional grade targeting suits consumer and automotive-grade tiers, and it is also used in drones and personal navigation devices requiring compact footprint and high sensitivity.
When designing with the UBX-G8020-KT, ensure the host processor issues periodic backup-mode control or activate the chip via enable pin to minimize quiescent draw on battery-powered wearables. Antenna matching network design directly impacts tracking sensitivity, and using a TCXO over a crystal oscillator improves weak-signal acquisition performance in challenging environments.

일반적인 애플리케이션
UBX-G8020-KT 적합 용도: 6 애플리케이션s: Wearable Fitness Tracker Positioning, Automotive Telematics Unit, Asset Tracker Module, Personal Navigation Device, Drone/UAV Positioning, Industrial IoT Positioning Sensor.
Wearable Fitness Tracker Positioning
The UBX-G8020-KT's -166 dBm tracking sensitivity and 50 mm2 footprint make it ideal for wrist-worn fitness trackers where PCB area is constrained and antenna gain is limited to 0 to 2 dBic. The chip's integrated LNA reduces external RF front-end component count, while on-chip LDOs and DC/DC converter simplify the power tree, enabling all-day battery operation with periodic GNSS fixes. Placed alongside a low-power MCU and a small patch antenna, the chip delivers 2.5 m to 4 m accuracy for run/cycle distance tracking without burdening the host processor with baseband computation.

Automotive Telematics Unit
The UBX-G8020-KT is targeted at standard professional automotive positioning, supporting GPS/QZSS/GLONASS with advanced jamming and spoofing detection critical for vehicle telematics. The chip's 1.575 GHz L1 reception and 2.5 m to 4 m accuracy satisfy insurance telematics, fleet tracking, and stolen-vehicle recovery accuracy requirements. Its QFN-40 package footprint is compatible with the UBX-M8030 family, enabling design reuse across consumer-grade and ADR4-2 automotive-grade telematics platforms while maintaining robust RF performance under vehicular thermal and EMI stress.

Asset Tracker Module
For battery-powered asset trackers deployed in logistics and supply-chain monitoring, the UBX-G8020-KT's integrated DC/DC converter and dual LDOs minimize external power-tree components, extending battery life on multi-year deployments. The -148 dBm to -145 dBm cold-start sensitivity enables fast first-fix acquisition even after prolonged shipping storage, while 2.5 m to 4 m accuracy supports geofencing and route reconstruction. The pin-compatible QFN-40 footprint allows seamless migration to UBX-M8030 production parts as the UBX-G8020-KT enters EOL per PCN UBXDOC-304424225-20911.

Personal Navigation Device
Handheld personal navigation devices benefit from the UBX-G8020-KT's multi-constellation reception across GPS, QZSS, and GLONASS, which improves satellite visibility under tree canopy and in deep urban canyons where single-constellation receivers fail. The chip's -166 dBm tracking sensitivity supports weak-signal lock during indoor wayfinding transitions, while the integrated RF front-end reduces BOM cost relative to discrete GNSS receiver architectures. The QFN-40 50 mm2 footprint is small enough for compact handheld enclosures and supports TCXO or crystal oscillator selection based on accuracy targets.

Drone/UAV Positioning
Small unmanned aerial vehicles rely on the UBX-G8020-KT's fast cold-start sensitivity of -148 dBm to -145 dBm to reacquire satellites rapidly after RF shadowing events such as banking maneuvers or proximity to buildings. The chip's jamming and spoofing detection prevents deliberate or accidental interference from corrupting flight controller position data, which is critical for autonomous UAV operation. Its compact 50 mm2 footprint and integrated power management suit weight- and area-constrained drone avionics bays, while pin compatibility with UBX-M8030 supports future migration as the UBX-G8020-KT enters EOL.

설계 노트
The UBX-G8020-KT is End-of-Life per PCN UBXDOC-304424225-20911 dated 2 March 2026. New designs should target the pin-compatible UBX-M8030 family from the outset to avoid forced requalification within 12-18 months. Existing designs with multi-year production should perform a last-time-buy analysis based on forecast consumption and authorized distributor stock to bridge the gap until UBX-M8030 migration.
Place the UBX-G8020-KT's RF input trace as a 50-ohm controlled-impedance microstrip or coplanar waveguide routed directly to the antenna or SAW/LNA matching network. Keep digital I/O and clock traces away from the RF input to avoid LO leakage coupling into the GNSS front-end. The integrated DC/DC converter requires a low-ESR input capacitor close to the supply pin and a ground via fence around the RF section for optimum noise figure at -166 dBm sensitivity.
Estimated: at 3.3 V main supply and active acquisition, the UBX-G8020-KT draws tens of mA continuous, dominated by the integrated DC/DC converter switching losses. For battery-powered wearable applications, use the backup-domain mode between fixes to drop quiescent current by 1-2 orders of magnitude, and consider a TCXO warm-up time budget of 100-300 ms when assessing cold-start TTFF against system-level responsiveness targets.
