APPLICATION OF THE METHOD OF NON-PRECISION MEASUREMENTS IN THE POSITIONING OF SHIPS IN BAYS USING LOCAL MULTI-POSITION RADIO NAVIGATION SYSTEMS

The possibility of using a local radio navigation system (LRNS) to ensure the positioning
of a marine vessel (MS) along the route with the necessary accuracy in places where global
satellite RNC signals may contain natural interference, and the geometry of movement of
the elements of the Satellite Radio Navigation System (SRNS) may not be sufficient to
meet the requirements for determining the location with the required accuracy, is relevant
in the present tense. The presented paper discusses the principle of constructing a local
radio navigation system for positioning small-sized naval vessels at a range of up to 100 km
with a standard deviation of no more than 1 meter. Rational options for the placement
of the reference stations of the LRNS are proposed to ensure the required accuracy, and
the problem of estimating accuracy is solved by processing measurements using the
method proposed in the work using both equal-precision and non-precision measurements.
