Abstract

FIELD: radio- navigational systems intended for solution of complex problems of short-range-navigation. SUBSTANCE: it is a pulsed-phase-measurement base link system using the principle of retransmission of reference signal by a well regulated station network with fixed coordinates. The system algorithms, structural substantializations of stations and receivers-computers interfaced with movable objects make it possible at instabilities of frequency standards 10to obtain highly accurate measurements of coordinates, excluding static and random errors caused by: - time delay of reference signal detection; - time instability of retransmission delay; - space fluctuations of radio wave phase. It is provided by formation of two frequencies, which in active operation of the station are emitted on the air successively in time. According to the results of measurement of time intervals between the reference signals, the receivers - computers determine the ranges to the reference stations, which are converter to the coordinates of the point of reception of signals. The radio-navigational system "Basis-A" provides for: - all-weather operation and servicing of an unlimited number of system users; - continuous automatic evaluation of the point coordinates, simplicity of servicing and data readout; - pilotless automated pilotage of ships in a complex fairway and recording of its accuracy; - arrangement of global networks enveloping large territories, and structures of a limited access; - high accuracy and reliability of measurements; - low-cost of equipment and minimum maintenances charges, operatorless operation. EFFECT: enhanced accuracy and reliability.

Изобретение относится к классу РИС предназначенных для решения сложных задач ближней навигации. Это импульсно-фазовая система, использующая принцип ретрансляции опорного сигнала упорядоченной сетью станций с фиксированными координатами. Алгоритм системы, структурные реализации станций и приемников-вычислителей, совмещенных с подвижными объектами, позволяют при нестабильностях опорных генераторов, равной 10-8, получать высокие точности измерения координат, исключая статические и случайные погрешности, обусловленные временной задержкой обнаружения опорного сигнала, временной нестабильностью задержки ретрансляции, пространственными флуктуациями фазы радиоволн. Это обеспечивается формированием двух частот, которые в активном режиме станции последовательно во времени излучаются в эфир. Приемники-вычислители по результатам измерения временных интервалов между опорными сигналами определяют дальности до опорных станций, которые пересчитываются в координаты места приема сигналов.

This is a pulse-phase system using the principle of relaying the reference signal by an ordered network of stations with fixed coordinates. The system algorithm, structural implementations of stations and computer receivers combined with moving objects, allow for instabilities of reference generators equal to 10 -8 , to obtain high accuracy of coordinate measurement, excluding static and random errors due to a time delay in detecting a reference signal, temporary instability of the relay delay , spatial fluctuations of the phase of radio waves. This is ensured by the formation of two frequencies, which in the active mode of the station are sequentially transmitted over time in time. Receivers-calculators according to the results of measuring time intervals between the reference signals determine the distance to the reference stations, which are converted into the coordinates of the place of reception of signals.
