On Jan. 3, Synaptics released the SYN4778, a small, low power, accurate GNSS integrated circuit for Internet of Things (IoT) devices. SYN4778 is designed to extend battery life, reduce product size, and enhance performance of advanced location-based services for IoT devices, including wearables, mobile accessories, asset tagging and tracking systems, UAVS and transportation navigation.
SYN4778 includes advanced multi-path interference mitigation using L5 band signals from GPS, Galileo, BeiDou, NAVIC, SBAS, and Quasi Zenith Satellite System (QZSS). The chip also uses L1 satellite bands to reduce the time to first fix, as well as the power consumed, improving end-user experience, and enabling product developers to add additional functionality and features to their IoT devices.
This GNSS chip includes LTE jamming and signal filtering, and continuous — highly parallel — search and track of all GNSS channels for greater positioning accuracy for LBS applications, specifically in urban environments. Additionally, it offers support for multiple operating systems and third-party software to enable a broader range of application-optimized IoT devices.
SYN4778 is currently only available to select customers.
