Is Vinasat-1 safe from storms?

In the face of information about possible major storms, there has been concern in Vietnam about the impact of storms from the operation of Vinasat-1 satellite - Vietnam's first geostationary satellite.

Mr. Dinh Quoc Tri, technical manager of F-Space Space Research Laboratory, FPT University, said the impact of strong magnetic storms on the operation of satellites on orbit is very large.Magnetic field vibrations in magnetic storms can lose communication signals between satellites and the ground and damage components in satellites.Depending on the level of impact, satellites can deviate from orbit, change speed or stop working, falling slowly and igniting in the atmosphere.

Day 4.8, Dr. Ha Duyen Chau, Institute of Geophysics, said: the storm from NASA experts is expected to affect the Earth from 18g GMT on the same day (1 hour Vietnam).The initial results of the Institute of Geophysics show that the impact of magnetic storms is not strong, with an intensity of only 107 nT.The Institute of Geophysics is continuing to monitor and analyze the storm data from this.

'In general, this is just a weak magnetic storm. With this intensity, magnetic storms do not affect the operation of Vinasat-1 satellite , 'said Dr. Chau.

According to Dr. Chau, based on the intensity of magnetic storms ranked by level G1 - G5 corresponding to weak, medium, medium, strong and very strong levels.In particular, storms from medium level (200 nT) or more are likely to affect satellite operation.The above judgment of TS Chau was confirmed by Mr. Hoang Phuc Thang, Deputy Director of Que Duong: "The recent storm did not affect the operation of Vinasat-1 satellite. All satellite control activities. still going on normally " .

Decades ago, due to lack of protection measures, there have been many satellite failures in the world due to the impact of magnetic storms.Today, when manufacturing satellites manufacturers have used materials that are highly resistant to magnetic variation, improving the ability of satellites to resist resistance to magnetic storms.
