2021/03/09 Mobile brand Xiaomi has launched a dual-frequency GNSS smartphone. Fitted with a Broadcom BCM47755 chip, the Xiaomi Mi 8 provides up to decimeter-level accuracy for location-based services and vehicle navigation, the company said. The Mi 8 smartphone represents a breakthrough in GNSS technology as the first commercial deployment of Broadcom’s dual-frequency BCM47755 chip designed for the mass market and introduced in September 2017. Until now, mobile location-based applications have been powered by single-frequency GNSS receivers whose location accuracy is limited to a few meters. However, in recent years GNSS systems have been launching satellites broadcasting signals on new frequencies to open up new possibilities. Specifically, Galileo has the majority of satellites with E1/L1 and E5/L5 frequency capabilities. The E1/L1 + E5/L5 GNSS chip can compute location with an accuracy of up to a few decimeters. Leveraging Galileo for increased accuracy According to the company, users of the Xiaomi Mi 8 and future models with dual-frequency GNSS will benefit from better positioning and navigation experience in urban environments. This is due to the unique shape of the E5/L5 frequency, which makes it easier to distinguish real signals from the ones reflected by buildings, reducing the multipath effect, a major source of navigation error in cities and other challenging environments. The numerous Galileo satellites broadcasting E5 make this improvement available for users all around the world. In addition, the simultaneous use of two frequencies reduces other sources of error, such as those due to the ionosphere, and the frequency diversity is more robust to interference and jamming. In addition to making existing applications more accurate, the enhanced position precision offered by dual-frequency GNSS will also create opportunities for new applications in areas such as augmented reality, vehicle navigation and mapping. Commenting on the product launch, European GNSS Agency (GSA) head of market development Gian Gherardo Calini said that the arrival of the first dual-frequency GNSS smartphone to the mass-market represents a breakthrough for users all over the world. “The enhanced accuracy provided will empower developers to create new applications that meet the growing high-accuracy location requirements of users and also open up applications that previously only ran in dedicated devices intended for professional use,” Calini said. “Broadcom is glad to gear up Xiaomi’s flagship smartphones with the very latest dual-frequency GNSS technology,” added Alex Chou, vice president of product marketing for the Wireless Communications and Connectivity Division at Broadcom. “Xiaomi Mi 8, the world’s first smartphone with BCM47755, will take smartphone GNSS navigation to a whole new performance level.” ”The importance of GNSS to modern life is undisputed, and is particularly important for smartphones,” said Zhiyuan Zang, Xiaomi’s director of product marketing. “Navigation and LBS-based apps these days require greater positioning accuracy to work effectively, and dual-frequency GNSS is the key to delivering a great user experience when using these apps. Xiaomi is delighted and honored to be the world’s first smartphone manufacturer to support dual-frequency GNSS. We will continue to pursue innovation for everyone to enjoy.” Access to raw measurements for geolocation The launch of the first dual-frequency GNSS smartphone, together with the opportunities offered by the availability of GNSS raw measurements in Android, creates exciting opportunities for the geolocation community, the company said. Access to raw measurements opens the door to algorithms once restricted to more advanced GNSS receivers. This, in turn, allows users to fully benefit from the differentiators offered by Galileo. Recognizing these opportunities, in 2017 the GSA engaged with academia and industry in the areas of navigation and positioning to innovate around this new feature as part of a GNSS Raw Measurements Task Force. Then, in January, the GSA published a white paper on the use of GNSS Raw Measurements in Android, providing developers with in-depth information on accessing and using raw measurements to implement advanced GNSS techniques in mass-market devices. Building on this work, the GSA and the Raw Measurements Taskforce shared their latest updates at a dedicated workshop — “GNSS Raw Measurements: From Research to Commercial Use” — held at the GSA headquarters in Prague on May 30, where Broadcom presented its encouraging test results from the dual-frequency BCM47755.
