In the modern world, there are a number of different navigation methods that can be used to determine a location. These range from manual methods to global navigation systems that are used to navigate within our planet, Earth. At this time, it seems that the navigation equipment of consumers of global navigation satellite systems is widely used. Given the challenging interference circumstances, navigation equipment for consumers of global navigation satellite systems is designed with the inclusion of interference compensators. It may be suggested that the use of an interference compensator in the navigation equipment of the consumer of global navigation satellite systems has the potential to increase the accuracy of solving the navigation problem, thereby allowing the user of such a system to determine their planned coordinates. However, it would appear that the accuracy characteristics of such complex systems are not yet fully described in the literature.
To address this challenge, we undertook a study to examine the joint operation of commercial navigation equipment from global satellite systems, namely ublox and u-core, in conjunction with an interference compensator developed by the company's specialists at JSC «SPE «Radiocommunication». During the course of our work, we connected the commercial navigation equipment of the consumer of global navigation satellite systems to an interference compensator and carried out long-term measurements. The measurement results were then processed by specialists from JSC «SPE «Radiocommunication» after a full range of tests were conducted. The tests included an examination of the system in a stationary state and during movement in the absence of interference and at a high level of interference. The tests were carried out in a laboratory with a radio-transparent roof, which allowed us to obtain a real navigation field of global navigation satellite systems at the receiving point. In the laboratory, jammers were installed at a distance of 1,5 m from the pivot device, which created an interference field.
The tests that were conducted indicated that it might be feasible to develop an interference-protected navigation receiver that could potentially address navigation challenges in challenging interference scenarios. This could be achieved by integrating an interference compensator developed by the experts at JSC NPP Radiosvyaz with commercial navigation receivers such as u-blox or u-CORE.
The tests demonstrated that it is possible to achieve a navigation accuracy of up to 2,73 m without movement and 3,67 m when moving, which could be a promising starting point for further development.
