In fact, most smart phones such as Xiaomi, Huawei, VIVO and other domestic brands carry Beidou navigation technology. However, in practical applications, especially in the field of smart phone navigation, users have issued more questions: Since mobile phones support Beidou Navigation, why not feel the existence of Beidou technology? Why more mobile phone companies are still willing to use GPS as a product highlight?
Mobile phone chip integration Beidou function into standard
"Daily Economic News" reporter found that millet official website found that Xiaomi Group's now selling millet, red rice series of mobile phone products support GPS, AGPS, GLONASS, Beidou four positioning methods. In Huawei mobile phone official website, in addition to a few glory play In the 7th edition, Huawei's 8e and other entry products do not support BeiDou Navigation. Others support the world's top four navigation systems. OPPO, VIVO, Jinli and other brands' official websites show that most of the company's mobile phone navigation features are described as supporting GPS. High-end flagship phones are also compatible with BeiDou.
The chip was once considered a bottleneck to curb the development of the Beidou industry. However, from the current situation, whether it is an international mobile phone chip giant or a domestic chip company has already adopted the Beidou as a standard, more and more mobile phone companies will also be Vector as a standard.
Zhou Weifang, vice president of domestic mobile phone chip company Ziguang Zengrui, told the “Daily Economic News” that all of his chip products support the BeiDou function. People in MediaTek told reporters that the latest Helio P60 and Helio P22 integrated BeiDou navigation function.
According to related Qualcomm sources, since the launch of the first processor supporting the BeiDou positioning function in the fourth quarter of 2013, subsequent satellite positioning functions have achieved support for BeiDou positioning, and at the same time, the high-pass internet of things chips have also begun to support. Beidou. Qualcomm's latest Xiaolong 845 is the industry's first mobile platform to support the China Academy of Information and Communication Technology's "Network-assisted Beidou/GPS Position Service Platform."
In addition to the mobile phone industry, Beidou Navigation is also widely used in public security, transportation, fishing, power, forestry, and disaster reduction.
A brokerage communications industry analyst told the “Daily Economic News” reporter that 'previously the chip cost was very expensive, but now it has dropped to about the same as GPS.' Beidou chip technology threshold is not high, generally do mobile phone chip companies, You can integrate these positioning functions along the way.
Why is it difficult for users to perceive the existence of Beidou?
At present, China has successfully launched eight Beidou-3 global networking satellites and a simple system is formed. It is expected that by the end of 2018, services will be provided for countries along the “Belt and Road” route and global services will be provided by 2020. More than half a century has been realized commercially. Compared with the GPS system, the Beidou System, an autonomous and controllable system, has applications in military, industrial, and consumer applications.
Under the background that BeiDou Navigation was used as a standard function for mobile phones, the reporter noticed that many mobile phone companies started to change the 'GPS' used to set menus to 'Positioning'. In fact, mobile phone companies are more willing to declare at the conference. Using the new GPS technology, when users use mobile phone positioning, Baidu navigation, etc., the first thing that is perceived is GPS.
In response, some analysts in the communications industry stated: 'At this stage, everyone still uses GPS as the primary method. Only if there is no signal from GPS, will they use BeiDou. ' Based on GPS and BeiDou, this is what we usually use in mobile navigation. The reason why Beidou is rarely felt.
A practitioner expressed similar views to reporters, indicating that Beidou is accepted by everyone as a process. Map software, such as Baidu maps, location data received by Gaode maps for the underlying chip, bottom-level positioning GPS, Beidou Both are running. The upper layer software habitually reports GPS data when it is presented.
Wu Dezhou, chief operating officer of Hammer Technology, told the reporter of “Daily Economic News” that the hammer mobile phone Beidou plan uses the Beidou navigation provided by the Qualcomm chip, and is still focusing on GPS positioning. Qualcomm technical personnel told reporters that the mobile phone chip The more satellite positioning systems supported, the more advantageous it is to improve the positioning function, but it also increases the difficulty in coordinating positioning signals with wireless signals, and the requirements for power control are also improved.
'Positioning on the mobile phone, Compass has no special advantages compared to GPS at this stage, and GPS has a first-mover advantage. It is imperative to improve the replacement power of mobile phones and other related companies. ' The above-mentioned communication industry analyst said. And attract mobile phone manufacturers from the Beidou system. The advantage of seeing, high precision becomes the greatest possible. 'High-precision navigation market is a blue ocean, the three generations of the Big Dipper catch up with the opportunity of GPS here.'
At this stage, China has initially built a Beidou ground enhancement “National One Network” consisting of more than 2,200 reinforcement stations to provide real-time meter-level, sub-meter-level precision positioning services nationwide, and provide it in 17 provinces and cities in the eastern part of the country. Real-time centimeters and post-processing millimeter precision services.
