About the paper Full textAbstract
The work is concerned with the alternative methods of determining the coordinates and time of a local point withoutglobal navigation satellite systems (GNSS). Currently, GNSS are practically non alternative methods of determining coordinates and time in transport and unmanned vehicles. At the same time, GNSS are vulnerable to electronic warfare (EW), which can be used by both intruders or opponents, and by law enforcement agencies. Based on a review of existing approaches to solving such problems, a local radio navigation system based on compact transportable radio beacons is proposed, which can be an alternative to GNSS. The advantages of a local radio navigation system over other alternative methods of navigation are described. The main advantages are the ability to deploy this system quickly, due to the mass and size characteristics of the beacons, ensuring their manual transportation, as well as the possibility of providing selective access due to a quick change of the carrier frequency according to a pre-agreed rule in the future. Also, such a rapid change of frequencies increases the system's resistance to EW equipment designed for both jamming and spoofing a signal. The general principles of constructing a local radio navigation system and the existing analogs are considered. The main idea is to use a rangefinder pseudorandom code similar to the codes used in GNSS. This approach simplifies the work allowing the use of already developed algorithms. The implementation of a local radio navigation system model based on the technical solutions available on the market is described. An experiment to determine the coordinates of a moving object was carried out, the conditions for performing the experiment and its results are given. Currently, the main problem in terms of hardware is the lack of a built-in time and frequency keeper, in the future it is planned to be included in the equipment. The main problem in processing measurements in order to obtain coordinates are numerous re-reflections caused by buildings and terrain details. Possible solutions to this problem may include the use of receiving antennas similar to GNSS antennas with Choke-ring technology, as well as modification of the signal processing software which will allow to filter the signals reflected.
