State Policy<br />
‣ <strong>GLONASS</strong> is a part of the critical state infrastructure providing<br />
national security <strong>and</strong> economy development<br />
‣ Creating, developing <strong>and</strong> sustaining the PNT infrastructure is a<br />
state responsibility<br />
‣ Use of <strong>GLONASS</strong> is m<strong>and</strong>atory for state entities <strong>and</strong> major<br />
sectors of economy<br />
‣ <strong>GLONASS</strong> is used in combination with other GNSS, terrestrial<br />
radio navigation, other navigation means<br />
‣ Basic civil navigation services are free of direct user fees<br />
‣ Open, free access to <strong>GLONASS</strong> information necessary to<br />
develop <strong>and</strong> produce user equipment<br />
‣ International cooperation on GNSS compatibility <strong>and</strong><br />
interoperability<br />

Summary<br />
‣ <strong>GLONASS</strong> system is an element of the critical state<br />
infrastructure, ensuring national security <strong>and</strong><br />
economy development, remains being a dual use<br />
system<br />
‣ Urgent <strong>GLONASS</strong> restoration, development <strong>and</strong> mass<br />
use is one of priorities of the Russian State policy<br />
‣ <strong>GLONASS</strong> development is in a progress in line with<br />
Federal <strong>GLONASS</strong> Program (scheduled up to 2020)<br />
‣ <strong>GLONASS</strong> – essential element of the international<br />
GNSS<br />
