Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizen Zaker, for the clue delivery! CTOnews.com, April 19, the thousand fathom location announced another upgrade of the ionospheric suppression function, launching the country's first large-scale ionospheric prediction function, which can predict ionospheric activity in the next three hours at the district and county level, just like the weather forecast.

According to reports, with the help of the prediction of ionospheric active changes, the cloud integrated RTK terminal at thousand fathom position can improve the fixed effect under the active ionospheric changes and help double the operation efficiency.

▲ ionospheric prediction function demonstration as one of the main error sources of the global satellite navigation system GNSS, the ionosphere has always been a key factor affecting the positioning accuracy in the field of high-precision positioning. With the arrival of the 27th solar cycle (expected to reach the peak in 2025), the ionosphere is becoming more and more active. In the construction sites such as engineering construction, road administration and bridge, mining, forestry, land and topographic survey, many high-precision RTK terminal equipment often can not be "fixed", and the "fixed precision" index can not meet the calculation requirements for a long time.

In order to solve the problem of ionospheric disturbance, thousand fathom location is the first in the industry to introduce a comprehensive solution to ionospheric interference. At the ionospheric perception level, in May 2022, thousand fathom location has released the industry's first real-time query tool for ionospheric active changes.

At the algorithm level, relying on the ionospheric active data in the past seven years, the anti-ionospheric algorithm is upgraded by means of machine learning, and at the same time, the ionospheric suppression function is provided by combining the quality factor at the terminal algorithm level. it can effectively solve the positioning problem of users under the super-active ionosphere.

Now, the ionospheric suppression function at thousand fathom location has been upgraded, and the ionospheric forecast can be queried directly through the handbook App software of the integrated cloud RTK device at thousand fathom location, or you can log in to query the ionospheric forecast through the thousand fathom knowledge inch service account.

▲ thousand fathom location RTK equipment solving link thousand fathom position said that the reason for realizing the ionospheric prediction function is that as the ionospheric active pole year approaches, the ionospheric changes will not only intensify, but even more anomalies will occur. This requires not only continuous observation of the ground station, but also continuous iterative optimization of the algorithm model.

With the ability to predict the ionosphere, the thousand fathom position ionospheric suppression algorithm model can be optimized by self-learning through prediction and verification of the results, and finally improve the fixed effect under the active changes of the ionosphere and help to double the operation efficiency.

CTOnews.com query thousand fathom location official website shows that thousand fathom location was established in August 2015, based on Beidou satellite system (compatible with GPS, GLONASS, Galileo) basic positioning data, using more than 3700 ground-based enhancement stations around the world, independently developed positioning algorithms and large-scale Internet service platform to provide users with centimeter-level positioning, millimeter-level sensing, nanosecond time service space-time intelligent services. In October 2019, the company completed round A financing of 1 billion yuan, with a valuation of more than 13 billion yuan.
