Vietnamese Missiles Will Be Guided by GLONASS


According to Roskosmos agency head Yuri Urlichich, starting in 2023, GLONASS’s orbit system will provide high-precision navigation services with six new high-elliptical orbiting satellites.

“The orbital group of the GLONASS high-altitude orbital space complex, which consists of six spacecraft, divided into pairs on three orbital planes, will form two routes on the Earth’s surface. Absolute precision will begin to be provided from 2023, “the leader introduced.

Currently, there are 4 global positioning systems through popular satellites such as US GPS, European Galileo, Russia’s GLONASS and China’s Big Dipper. In that they provide extensive civilian channels and only to military channels for close allies use.

In the military field, satellite positioning plays a very important role. This is the main reference channel for land-cruising missiles and is an important tool for long-range anti-ship missiles, as it will be based on satellites to more accurately determine their flight path in the next phase. Targeted in inertial mode.

Currently, Vietnam has been equipped with the 3M-14TE Kalibr anti-flagship cruise missile version and is preparing to build the KCT 15 anti-ship missile, which is expected to feature the 3M-24UE. Shoot up to 260 km. Therefore, the use of satellite military channels is very necessary.

Recently, the vice-president of the Russian Federation, Yevgeny Bushmin, said Moscow was very supportive of concluding an intergovernmental agreement with Vietnam on the development and use of navigation systems. GLONASS satellite.

“We support the early conclusion of an intergovernmental cooperation agreement on the use and development of the GLONASS satellite navigation system,” Bushmin told a meeting with delegation from Vietnam.

This is paving the way for Vietnam to have extensive access to satellite navigation services from Russia’s GLONASS network, including applications in the military field, in addition to traditional civil applications. .

The foundation of the GLONASS system consists of 24 satellites, which travel on the surface of the Earth in three orbits with an inclination of 64.8 °, and an altitude of 19,100 km. The first satellite of the GLONASS was put into orbit on October 12, 1982, on September 24, 1993 the official system was put into use.

The GLONASS satellites continually emit positioning signals in two forms: the standard positioning accuracy (Ch) at L1 (1.6 GHz) and the high positioning (C) At frequencies L1 and L2 (1.2 GHz). The information, provided by the location signal Сh, is open to all users on a global and continuous basis and is guaranteed when using the GLONASS receiver.

They are capable of identifying horizontal coordinates with a precision of 50-70 m (99.7% confidence); vertical coordinates with 70 m accuracy (99.7% confidence); component velocity vector with accuracy of 15 cm / s (99.7% confidence); Accurate time accuracy with 0.7 mcs (99.7% reliability).

Accuracy can be increased significantly, using special positioning and / or supplementary measurement methods. C signal is basically assigned to the needs of the Russian Ministry of Defense, and can not be used without permission.
