GOST R 51794-2008 PDF

Full title and description

GOST R 51794-2008 — "Глобальные навигационные спутниковые системы. Системы координат. Методы преобразований координат определяемых точек" (Global navigation satellite systems. Coordinate systems. Methods for transforming the coordinates of the determined points). The standard defines coordinate systems used in GNSS/GPS/GLONASS contexts and prescribes methods and numeric parameters for transforming coordinates and coordinate increments between those systems.

Abstract

This national standard specifies the coordinate systems that form the geodetic parameter systems (including national reference frames and world geodetic systems) and gives algorithms and recommended numeric transformation elements for converting coordinates and coordinate increments from one system to another. It also contains mandatory appendices with transformation elements between PZ-90, Pulkovo systems, the World Geodetic System (WGS) and national Russian reference frames.

Scope

The standard applies to coordinate systems that are part of the geodetic parameter systems ("Parameters of the Earth"), the World Geodetic System, and the coordinate reference frameworks of the Russian Federation. It establishes the methods for transforming coordinates and their increments between these systems and prescribes how to use numeric values of transformation elements when performing geodetic, navigation and cartographic work with consumer GNSS equipment and processing software. Mandatory appendices provide recommended transformation elements between refined/primary systems (PZ‑90 series, Pulkovo realizations, WGS).

Key topics and requirements

• Definitions and formal description of coordinate systems used in GNSS/GLONASS/GPS contexts (geocentric and geodetic systems).
• Algorithms and mathematical methods for transforming coordinates and coordinate increments between reference frames (including seven-parameter and related transformation techniques).
• Mandatory appendices with numeric transformation elements linking the national reference frames and international systems (PZ‑90, Pulkovo 1995/1942 variants, WGS84 etc.).
• Rules for applying transformation parameters in geodetic, navigation and cartographic workflows and for use in consumer receiver processing and mapping products.
• Amendments recorded in 2011 and 2013 that clarify and correct numerical elements and application notes.

Typical use and users

Primary users include national and regional geodetic agencies, surveyors, cartographers, GIS and mapping software developers, GNSS system integrators, and defence or infrastructure organisations that require consistent coordinate transformations between national and global reference systems. The standard has been referenced in Russian geodetic and cartographic literature and in GNSS processing/tool implementations for coordinate conversions.

Related standards

Predecessor: GOST R 51794-2001. Related and complementary Russian standards cover GNSS terminology, geodetic network requirements and geodetic monitoring methods (for example GOST R 53864-2010, GOST R 55535-2013 and other GOST documents addressing geodetic networks and GNSS methods). Implementations and software tools for coordinate conversions often reference both the 2001 and 2008 versions and later GOST/Interstate standards when performing datum/frame transformations.

FAQ

Q: What is this standard?

A: A Russian national standard that defines coordinate systems used with global navigation satellite systems and prescribes methods and numerical elements for transforming coordinates between those systems.

Q: What does it cover?

A: It covers the formal definitions of geodetic coordinate systems, mathematical methods for converting coordinates and increments from one frame to another, mandatory appendices with transformation elements between national and global systems (PZ‑90, Pulkovo, WGS), and rules for applying these parameters in geodetic, navigation and cartographic work.

Q: Who typically uses it?

A: Surveyors, geodesists, cartographers, GNSS software and device developers, national mapping agencies and organisations performing precise coordinate transformations in Russia and neighbouring regions.

Q: Is it current or superseded?

A: GOST R 51794-2008 was approved in December 2008 and came into effect on 1 September 2009; its national action was ceased (withdrawn) on 1 July 2014. Users should consult current national and interstate geodetic standards and the latest official documents from Rosstandart / relevant authorities for up-to-date transformation rules.

Q: Is it part of a series?

A: Yes — it belongs to a body of Russian GOST/GOST R standards dealing with GNSS, geodetic networks, terminology and geodesy; it directly follows earlier GOST R 51794 editions and is associated with other standards that govern geodetic practice and GNSS usage in Russia.
