Radio-optic positioning systems based on mobile communication infrastructure in problems of ground objects

Abstract

The article considers the problem of constructing an autonomous positioning system of  objects using the infrastructure for mobile communications (repeater towers, cell phones) without the constant attraction of satellite navigation systems. It is shown that the use of dual-wavelength optical line for synchronization of  spaced  transmitters of towers gives error positioning of objects up to 10-20 mm. It is necessary to use additional control  of moving of peaks towers and meteorological parameters both at the location of towers and at the location of controlled object. The paper is numerically investigated the difference between electrical and optical paths of propagation channels    from humidity, pressure and temperature It is shown that if, along with the radio - frequency, repeater  will emit a modulated optical signals, by measuring the difference between electrical and optical paths, the positioning of object can be measured with an accuracy of about 1 mm. Such systems may be useful in the case of deformation measurements in the unavailability of satellite positioning systems in the case of need for greater efficiency of data retrieval.
