At the same time, industry experts noted that there are alternative methods for determining location. For example, it is possible to develop positioning systems based on stationary Wi-Fi routers. This was reported by Dmitry Egorov, senior lecturer at the Department of Television and Sound Broadcasting at the Moscow Technical University of Communications and Information.
“This system has already kuwait whatsapp number database been partially implemented, since if the satellite signal is disrupted, navigation devices can switch to Wi-Fi access points, but now this method is very energy-intensive and does not provide great accuracy, so it is best used as a backup,” the specialist noted.
In his opinion, to increase the correctness of the system, developers should invest in infrastructure and supplement Wi-Fi access points where necessary. It is also necessary to create appropriate programs for both gadgets and servers where information is stored and processed.
Another solution could be Ultra-Wide Band systems. This is a communication technology that provides high data transfer speed and accuracy in determining the location of objects. At the same time, it allows you to set geolocation for a limited number of gadgets, so it can be used, for example, for municipal transport navigation services.
— The coordinates of an object can be determined using signals from cellular base stations. But they provide errors of 10 to 30 m. Alternative geolocation methods can be developed based on high-precision synchronization systems of base stations and specialized navigation receivers. They allow solving navigation problems with an accuracy of up to tens of centimeters, — explained Vladimir Grigoryev, CEO of the company "Infocommunication Networks Laboratory".
The specialist specified that technical solutions for implementing such a project exist, but their implementation requires political will, since it is necessary to implement special hardware and software solutions in gadgets. This is difficult to implement, since at present, Russian consumers mainly have imported cellular network equipment, so access to the software filling of devices is limited.
At the same time, failures in the operation of applications with navigators can occur at the level of software solutions, experts noted. In particular, an expert at the Moscow Institute of Physics and Technology spoke about this.
"It is possible that the bulk of the code for one of the most popular domestic navigation services was made outside the country. As a result, the application receives "dirty" data in places where electronic countermeasures are used," he commented.
According to an anonymous source from MIPT, the problems could have been avoided if the developers of the navigator app had invested in visual odometry technologies in time. It is used to measure distances by counting the number of wheel revolutions or steps. This method is used, for example, in fitness trackers and driverless cars, but with some modifications and in combination with other systems, it can also be used in navigators.
In addition, it would be possible to restore "corrupted" satellite data in areas of radio-electronic interference using video footage from a camera mounted on the windshield of a car. There is also a method for combining hypotheses about the geolocation of nearby vehicles. It is carried out using automatic "polling" of car navigation systems via Bluetooth channels - a wireless technology for exchanging data over short distances.
Problems with the operation of navigators may also be related to space "weather", said Tatyana Podladchikova, director of the Center for System Design at the Skolkovo Institute of Science and Technology.
— Energy particles are formed as a result of, for example, solar flares or supernova explosions. By bombarding terrestrial spacecraft, the particles destroy control systems and disable satellites, — the expert said.
In her opinion, the improvement of navigation systems is connected with the development of methods for forecasting space phenomena and strengthening the protection and increasing the efficiency of satellite groups. In particular, one of the ways to solve this problem was proposed by scientists from the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences with the support of the Russian Science Foundation. They developed a model based on artificial intelligence, which allows forecasting the number of electrons in the ionosphere. Scientists believe that the algorithm will help make global navigation satellites 15% more accurate.
