Russia Develops a technology for navigation without satellites
The Russian state corporation Rostek has developed a new technology of local radio navigation with effective protection against interference and increased accuracy in comparison with satellite systems. The technology allows determining the position of objects with an initial accuracy of up to 10 cm. For comparison, this indicator for satellite navigation systems varies in the range of 1-3 meters. Experts consider unmanned vehicles as one of the promising areas of the new technology.
“The system almost completely excludes the possibility of third-party impact in order to distort or steal navigation data. This is one of the main differences in the development from the global navigation systems GLONASS, GPS and Galileo, whose signals are well known, constant and can be exposed to hostile targets, “the Rostek representative said.
The local navigation system is based on the use of the rangefinder principle. To determine the position of an object in space, measure the distance from it to several points with known coordinates. At the moment, researchers at Rostek are testing four transmitting devices using a new navigation system. The next step will be testing the system using the towers of mobile operators. If everything goes according to plan, in the future the local navigation system will be able to operate at a distance of 50-70 km to the nearest base stations.
It is expected that in the future this technology can be used in ground unmanned vehicles, where traffic safety requires accuracy within 10 cm.
