Description

The invention relates to methods for determining the distance between points on the surface of the Earth using global space systems (GCS) GPS and GLONASS.

A known method for determining the distance between points on the surface of the Earth using geodetic methods. The disadvantage of this method is the extreme complexity of the work when measuring distances at large bases in areas with limited direct visibility (forest and mountains).

There is also a method of measuring distance when using the global space systems GPS and GLONASS, including equipping fixed points with "known" coordinates from which signals are continuously transmitted to correct pseudo-orbit satellites, setting custom points between which it is necessary to determine the distance (basis) and the position of which is calculated when measuring distances from several satellites to these points when making serifs on the surface of the Earth and using the mathematical apparatus [2].

GPS and GLONASS systems for simplification are based on the constant and maximum radius of the Earth, equal to an average of 6371 km, typical for 1990 and the beginning of 2002, which was approved by order of the Government of the Russian Federation of June 20, 2007 No. 797-R. The Russian Ministry of Defense and Roscosmos should ensure the implementation of an updated version of the state geocentric coordinate system "Earth parameters 1990" (PZ-90.02).

A disadvantage of the known methods is that, as a result of the radiation of the Cosmos, the size of the Earth can change with a cycle of 11 years in relative units by ε AF = (2-4) ⋅ 10 -4 or more (see Fig.) [3]. As a result of this, the coordinates of points and bases change over time.

The aim of the invention is to improve the accuracy of determining the distance between user points when using GCS systems, taking into account the periodic changes in the size of the Earth.

This goal is achieved by the fact that on the surface of the Earth equip landfills, where between stationary points periodically measure the distance by GPS, GLONASS and geodetic methods, for example using laser rangefinders. Find the length of the bases between points using the GCS L GCS , which must be const, and the geodetic measurements L i (t), which varies over time, determine their ratio L i (t) / L GCS = K i (t). Next, they build graphs of their changes to date and mathematically substantiate the forecast for the near future for individual territories and regions.

Users determine the coordinates of points and bases when using the GCS G GCS and find the exact length of the basis at a specific time according to

Figure 00000001

To increase the accuracy of determining L i (t), it is advisable to equip the polygons in underground workings on the basis of tens and hundreds of meters outside the influence zone of underground work in mines, using geodetic methods to determine the relative deformation of the rock mass ε m , build a graph of its change since 2002 ε m (t) and introduce a correction to the bases on the surface using the dependence

Figure 00000002

The dependence ε M (t) = ε AF for the territory of the Urals has been reliably rebuilt since 1998 (represented by the figure), and it can be used to determine exact bases on the Earth's surface, taking into account that

Figure 00000003

where K i (t) = 1 + ε i (t);

For a fundamental solution of the problem posed, it is necessary to build the actual surface of the satellite’s orbits by inter-location between GC satellites in orbit, build the actual surface of the Earth from satellites to permanent points on the Earth’s surface and determine the coordinates of user points and the distance between these points using well-known technologies and mathematical apparatus.
