1 Functional description UBX-G7020-KT/KA - Data Sheet 1.1 Overview Featuring a single die solution, low power consumption and low costs, the UBX-G7020 GPS/GNSS chips are multi-gnss (GPS, GLONASS, Galileo and QZSS) positioning chips developed to meet the requirements of an extensive range of applications and end-products. Based on the high performance u-blox 7 position engine, these receivers provide exceptional sensitivity and acquisition times without requiring an external host. u- blox advanced RF-design and interference suppression measures enable reliable positioning even in difficult signal conditions. u-blox 7 technology delivers high performance with low power consumption and low costs. An integrated DC/DC converter and intelligent power management are breakthroughs for low-power applications. The minimal BOM requires as few as 8 external components and the small footprint further reduces costs by enabling 2-layer PCB integration. LDOs and an LNA are built-in and costly external memory is not needed. This makes UBX G7020 positioning chips the ideal solutions for cost sensitive applications that don t require firmware update capability. For applications needing firmware update or data logging capabilities the UBX-G7020 can be connected to an external SQI Flash memory. Lower price GPS/GNSS crystals as well as high performance TCXOs are also supported. 1.2 Highlights and features u-blox 7 position engine featuring: over 2 million effective correlators down to 1 s acquisition time -148 dbm coldstart acquisition sensitivity and -162 dbm tracking sensitivity up to 10 Hz update rate Supports data logging Intelligent, user configurable power management and a built-in DC/DC converter for significantly lower power consumption compliant Supports u-blox AssistNow Online / AssistNow Offline A-GPS services and is OMA SUPL Faster acquisition with AssistNow Autonomous (no connectivity required) Supports GLONASS and is ready for Galileo Supports Crystal and TCXO oscillators Minimal BOM costs and minimum board space (< 30 mm 2 ) for a complete receiver implementation Standard and automotive grade 5.0x5.0 mm 2 QFN40 package with 0.4 mm pitch. This package offers the most cost-effective form of u-blox 7 technology. GPS.G7-HW-12001-4 Advance Information Functional description Page 5 of 39
