Transactions Is. 43. — SPb.: IAA RAS, 2017. - 156 p.

This special issue of the Transactions of IAA RAS contains the materials of the PNT-2017 — the All-Russian Conference which took place in April 2017 in the IAA RAS, St. Petersburg and was devoted to the fundamental and applied scientific research in positioning, navigation and timing (PNT). The articles collected here cover a wide range of theoretical, methodological, organizational and legal PNT issues. Particular attention is paid to the GLONASS system in the aspects of its maintenance, usage and development; the reference systems created and maintained; the Earth orientation parameters monitored; time scales stored and synchronized; the Earth’s gravity field and its parameters being determined, etc.

The following modern high-precision technical means and methods of PNT are described in detail: radio interferometric network with very long baselines; satellite and lunar laser ranging systems; global navigation satellite systems; time and frequency standards; geographic information systems, etc. Various methods to colocate different technical means are considered.

These articles are written for specialists in physics and astronomy.
