There is a popular saying in the human exploration of civilization: our journey is a sea of stars. In order to conquer nature, we have continuously explored and invented many devices and instruments to solve the question of where am I? Starting from Magellan's global voyage, people's eyes are no longer confined to the land under their feet, but have set their sights on the vast universe.
From the mobile Internet to the Internet of Things, location, as the most basic and indispensable information, is becoming more and more important for high-precision positioning services as industry applications develop in the direction of increasing refinement. We can know the location of things more accurately. When cabs, drivers can more accurately understand the location of passengers, and enterprises can better manage personnel or materials.
How much imagination is there for high-precision positioning in industry applications?
In first and second-tier cities, residents are no strangers to bike sharing and car sharing, which has become a milestone in the development of human civilization. Exclusive download APP you can find the location and distance of the nearest car. Shared cars can use Beidou high-precision positioning Inertial navigation integration, combined with vehicle geo-fencing, to achieve accurate use and return; in the field of mass consumption, smartphones are the most typical application of the Beidou system. According to relevant statistics, in 2019, more than 70% of China's cell phones will support the Beidou positioning system; in agricultural plant protection scenarios, DJI drones are equipped with Beidou precision positioning technology, which improves positioning accuracy to the centimeter level and ensures that routes are accurate and repeatable.
From the development of many of the above fields, high-precision GNSS positioning has become a multi-industry, multi-scene application. In order to promote the extensive service of this technology to people's lives, high-precision satellite positioning products have begun to develop rapidly.
Development of high-precision positioning products in surveying and mapping industry
According to the level of application, satellite positioning products can be divided into professional application products and consumer application products, while high-precision satellite positioning products are mainly used in the fields of surveying and mapping, GIS collection, engineering measurement and positioning, and fine agriculture. The field of surveying and mapping is the earliest, most mature and sophisticated application field.
Surveying and mapping industry in the late 80s and early 90s began to apply GPS With the continuous development of the domestic surveying and mapping market, the traditional surveying and mapping technology and production model had to rapidly transform into a digital production system, the mass production of digital surveying and mapping products are emerging.GPS technology breakthroughs, the rapid popularization of static GPS products in China and the rapid popularization of dynamic RTD, dual-frequency RTK product research and development were initiated one after another, and promoted in the market.
From the point of view of the surveying and mapping industry itself, with the deepening and expansion of the surveying and mapping digital production system, high-precision RTK state-owned, large units of the industry to small and medium-sized, private surveying and mapping units and teams began to popularize the products, such as surveying and mapping field collection tools.
After that, the main body of high-precision positioning products changed from static products to RTK products, NRS CORS network system and high-precision GIS collection also appeared one after another. This series of changes marks our gradual entry into the era of information mapping.
Throughout the development of technology in the entire surveying and mapping industry, the omni-directional, highly dynamic, digitalized and networked geographic information service model puts forward higher requirements for current and future high-precision navigation equipment. This is why the surveying and mapping industry, as a traditional and important field, is increasingly inseparable from high-precision positioning services.
After talking about the surveying and mapping industry, let's take a look at the field of intelligent driving.
How does high-precision GNSS locate automatic driving?
In fact, automatic driving can be said to be high-precision GNSS positioning technology is a very important application scenario. The industry divides automatic driving into five levels according to the degree of intelligence. We often mention driver assistance, automatic driving and driverless actually represent different degrees of intelligence and high precision automatic driving GNSS positioning is more empowering L automatic driving 2 or more.
In recent years, there are the following bottlenecks in the development of autonomous driving localization technology:
1. usability problems of the positioning system (poor user experience caused by various sensor failures);
2. safety issues of automatic driving systems above L3 level;
3. increase in system cost due to upgraded sensor performance requirements;
Different levels of autonomous driving intelligence have progressive requirements for positioning, with positioning distances ranging from 10 meters to sub-meters, and even centimeter-level requirements for L3 level and above. To meet this series of requirements, five necessary spatial and temporal benchmark factors are required:GNSS Waystar, high-precision maps, territory-wide communication network coverage, territory-wide unified benchmark GNSS base stations, and good performance mobile terminal GNSS receivers.
The role of high-precision maps is to allow the car to remember the route GNSS positioning in complex scenes temporarily lose the perception of space, the vehicle can walk normally through real-time perception and memory data. The current high-precision positioning is usually through RTK acquisition technology.
At this stage, high-precision GNSS positioning technology is to correct the map through post-processing. The accurate measurement for the basic ground markers is the best comparison standard for the car in the autonomous driving scenario. In addition, high-precision GNSS positioning High-precision maps can also realize many intelligent driving assistance functions. For example, alerting drivers of sharp turns, ramps, intersections and some known accident points ahead for a better driving experience.
Whether in the mapping industry or in the field of autonomous driving, it is easy to see that the greatest benefit that high-precision positioning services bring to users is to make information management more accurate. Therefore, its importance and value is even more obvious.
