A local innovative enterprise from Shanghai
-Chihiro Location
Let Xiaomi, Huawei, Many mobile phones of
domestic brands such as Glory
are the first to have such ultra-high precision positioning capability
ahead of other brands in the world
Not only mobile phones
a number of cars that realize autonomous driving
unmanned aerial vehicles
have used this spatio-temporal intelligent service
and it has been fully promoted in Shanghai. In the critical period of digital transformation, Chihiro is committed to promoting Beidou's high-precision positioning and timing technology from the laboratory to the mass commercial market, and is constantly carrying out technological innovation from to 1 and scene application from 1 to N.
before crossing multiple thresholds and rushing to the market
, the threshold for obtaining high-precision location services was extremely high. Generally speaking, it is necessary to temporarily set up reference stations to obtain satellite positioning calibration numbers, and expensive equipment is needed at the terminal level to receive high-quality satellite signals and communication stations to receive calibration numbers.
Chihiro is the first in the world to build a large-scale
satellite ground-based augmentation system
and broadcast it through the Internet for 24 hours
to provide users with high-precision positioning and timing services
through ground-based augmentation and satellite-based augmentation. The integration technology
provides the high-precision space-time service of "satellite-earth integration"
meets the needs of users in the intelligent era for accurate space-time service
Seamless and continuous availability
Building such a network is only the first step. To reduce the application threshold of technology, there are still many hurdles to be overcome, such as cost, power consumption, algorithm, chip, communication ability, computing ability and so on.
"It is a difficult problem for us to solve how to achieve the positioning accuracy equivalent to that of a measuring device with a cost of 1, yuan, and at the same time provide more stringent availability and integrity requirements." Wang Denghui, an expert on Chihiro location algorithm, said.
At present, Chihiro's exploration practice has been adopted by an internationally renowned automobile manufacturer. Through massive reference station data and large-scale road test data samples, Chihiro constantly adjusts and iterates the performance of the algorithm to solve many key technical difficulties in complex dynamic scenes. Chihiro also introduced the integrity index of aviation field and the functional safety index of industry into the space-time intelligence field in a breakthrough way. Software development based on spatio-temporal intelligence to build car-gauge products can meet the high-standard software development needs of mainstream automobile manufacturers and first-class suppliers.
develop the ability of "positioning" in the new scene
face customers directly, Exploring
in the scene is the best way of technology industrialization
Chihiro location
has a lot of advantages in application scenarios
It has provided a boost fuel for the mass application of Beidou high-precision technology
for a long time. Because of the high technical difficulty and unclear business model, no one in the industry dares to try to make a mobile phone, the most widely used mass consumer electronic product, have high-precision positioning capability. However, if the mobile phone can have high-precision positioning capability, it will bring revolutionary user experience upgrades to super applications such as navigation, games and local life.
after 19 months, Chihiro took the lead in opening the whole link from Beidou high-precision positioning technology to mobile phone terminals and mobile applications in the industry. At the same time, it optimized the positioning service algorithm, improved the broadcasting ability, and supported the large-scale and high-concurrent access requirements of billions of users.
Mobile phones are just the epitome of Chihiro's efforts to promote the industrialization of Beidou's high-precision technology.
With the help of Chihiro's position, a number of new spatio-temporal intelligent species with Beidou's high-precision positioning ability were born in combination with new scenes, and infiltrated in various fields such as intelligent things, smart cities, smart driving and smart power grids.
turning spatio-temporal intelligence into "hydropower coal"
spatio-temporal intelligence services are playing an increasingly important role. Since July 19th, continuous extremely heavy rainfall has caused serious floods in Gongyi, Henan Province. Many sub-high pressure gas pipelines in Gongyi were washed out by rain and exposed.

At the critical moment, relying on the Beidou ground-based augmentation system "One National Network" built in Chihiro, the UAV can quickly obtain centimeter-level high-precision positioning service and realize accurate flight according to the specified pipeline route. After a five-hour flight, the drone took a large number of videos and photos with high-precision time and space tags.
On July 26th, engineers of rescue team
took off unmanned aerial vehicle in Gongyi
Engineers of Chihiro Location imported thousands of photos taken into Chihiro Cloud Image, a cloud 3D high-precision real-life reconstruction platform developed by Chihiro Location, to build a 3D model of gas pipelines in key areas, and finely restore hidden pipelines, which provided a scientific basis for disaster relief and won valuable time.

From the groundbreaking "One National Network" technology mode to the breakthrough "Satellite-Ground Integration" scheme, Chihiro Location has never stopped exploring in the field of spatio-temporal intelligence technology, taking the lead in promoting the industrialization and commercialization of Beidou's high-precision technological achievements.
in order to solve the world problem of "ionosphere interference to satellite navigation signals", Chihiro Location and Fudan University's scientific research team * * * launched the research of "ionosphere modeling and forecasting technology driven by big data based on Beidou ground-based augmentation network".
since its establishment more than six years ago, Chihiro has applied for 559 patents, including 537 invention patents, covering satellite navigation technology, artificial intelligence, machine learning technology and other fields and disciplines.
Chihiro started from scratch as a pioneer and ran out of a new track of space-time intelligence, which was born in Beidou, not just in Beidou. "Facing the future, in the virtual world composed of countless zeros and ones, we also need a high-continuity, high-stability, high-availability and high-security space-time network to turn space-time intelligence into infrastructure like water, electricity and coal, and become a bridge connecting the virtual and real worlds, stimulating the innovation potential of the era of all things intelligence." Chen Jinpei, CEO of Chihiro Location, said.
