White Paper

The high performance UBX-G7020 multi-GNSS chip supports GPS, GLONASS, QZSS and SBAS. It delivers exceptional sensitivity and acquisition times. u‑blox 7 features ultra low power consumption, thanks to innovative single die architecture and enhanced software algorithms. This gives the UBX-G7020 best in class power consumption for GLONASS reception. The extended voltage supply range and 1.8 V and 3.0 V I/O compliance supports a wide variety of user applications. Sophisticated RF-architecture and interference suppression using active continuous wave detection ensure maximum performance even in GNSS-hostile environments. The UBX-G7020 is available in your choice of miniature WLCSP and QFN packages and features an ultra small solution footprint of only 30 mm2. The built-in LNA, LDOs and DC/DC converter, and on-chip ROM mean that only the smallest possible external BOM is required. By supporting TCXOs or lower price GNSS oscillators the UBX-G7020 further ensures a minimal Total-Cost-of-Ownership. The ultra small UBX-G7020-CT is the perfect choice for portable consumer applications with demanding size and cost constraints. With its rigorous Automotive quality and manufacturing standards (AEC-Q100, ISO/TS 16949) the UBX‑G7020-KA is ideal for automotive applications.
