Recently, the European Global Navigation Satellite Systems Agency (GSA) reported the news of Xiaomi 8 on the official website.
Recently, the European Global Navigation Satellite Systems Agency (GNSS) (Global Navigation Satellite Systems) is a GNSS receiver that passes through a series of navigation and positioning satellites in space to the ground. The signal with time and position data is transmitted and the receiver then uses this data to calculate the position.
By definition, GNSS systems provide global coverage, including Galileo of Europe, GPS of the United States, GLONASS of Russia and China's Beidou satellite navigation system.
According to GSA, Xiaomi 8 is the world's first smart phone equipped with dual-band GNSS, and is also the world's first handset capable of providing decimeter-level positioning and navigation accuracy.
The full text of the report is as follows:
Xiaomi 8 was released on May 31 and equipped with Broadcom's BCM47755 chip. It became the world's first smart phone that can provide decimeter-level positioning accuracy for location services and car navigation.
Xiaomi has released the world's first smartphone supporting dual-band GNSS. Xiaomi 8. This smart phone can be said to be a breakthrough representative of GNSS technology, and is also the first commercial use of Broadcom's revolutionary BCM47755 chip.
The Broadcom BCM47755 released last year is a chip that supports dual-band (E1/L1+E5/L5) GNSS. It can improve the positioning accuracy to the decimeter level. Previously, mobile applications relying on location services were limited to single-frequency applications. GNSS, its accuracy has been limited to meters. However, in recent years, GNSS has launched many satellites supporting new frequency bands. In particular, Galileo positioning systems mostly consist of satellites with E1/L1+E5/L5 frequency bands. Positioning accuracy adds new possibilities.
Use Galileo satellites to increase accuracy
Millet 8 and users of terminal products that will use dual-band GNSS in the future will all get better positioning and navigation experience in the urban environment. Depending on the specificity of the E5/L5 band, this band can more easily distinguish the real signals. And buildings reflect signals to reduce the impact of multipath effects (multipath effects are the main source of navigation deviations in cities and other challenging environments). A large number of Galileo satellites can broadcast E5 signals to provide global users with positioning Accurate improvement. In addition, the use of dual-frequency signals at the same time can reduce the signal errors caused by the ionosphere, multi-frequency signal more anti-jamming capability.
In addition to the more precise positioning of existing applications, dual-band GNSS offers new opportunities for new applications such as augmented reality, vehicle navigation, and mapping.
Gian Gherardo Calini, head of market development at GSA (European Global Navigation Satellite System Bureau), commented on the product's release that the world's first dual-band GNSS smartphone has entered the mass market as a breakthrough for users all over the world. 'More accurate positioning. Accuracy can help developers create new applications to meet higher and higher positioning requirements, and can also open applications that previously could only be run on dedicated devices.
Alex Chou, vice president of product marketing for Broadcom’s Wireless Communications and Connectivity Division, said: “Broadcom is pleased to see Xiaomi’s latest flagship phone using dual-band GNSS technology. Xiaomi 8 is the world’s first smartphone to use the BCM47755. Positioning navigation has raised a whole new level. '
Xiao Zhi Product Marketing Director Luan Zhiyuan said: 'Global Positioning System is a very great invention, especially important for smart phones. Today's Map Navigation App and LBS-based App are more and more accurate for positioning, dual-frequency GPS can effectively enhance them. The experience. Xiaomi is honored to be the world's first mobile phone manufacturer to support dual-band GPS function. We will continue to innovate so that every consumer in the world can enjoy the good life brought by technology.
A new era of location services
The release of the world’s first dual-band GNSS smartphone, coupled with access to GNSS raw data provided by Android, creates exciting opportunities for location-based service developers. Access to GNSS raw data is more advanced for mobile phones The positioning algorithm has opened the door, only previously more advanced satellite positioning receivers were able to use related algorithms. This allows ordinary users to fully enjoy the unique advantages of the Galileo positioning system.
Taking into account the above opportunities, starting last year, the GSA (European Global Navigation Satellite System Bureau) encouraged relevant scientific research units and companies in the field of satellite navigation and positioning to innovate around the original GNSS data and as part of the GNSS Raw Data Working Group. In January this year, The GSA has released a white paper on the use of GNSS raw data in the Android system, providing developers with an in-depth introduction to the raw data, and applying this data to guide the introduction of advanced GNSS technology for mass market devices.
On this basis, the GSA headquarters in Prague will hold a workshop on May 30th with the theme 'GNSS raw data: From research to commercial'. At the meeting, the GSA and GNSS Raw Data Working Group will share this area. The latest developments, Broadcom will also announce the excellent test results of the dual-frequency positioning system BCM47755.
