VINASAT-1 comes to orbit 131 degrees East!

Director of VINASAT Satellite Project Management Board, Hoang Minh Thong said, as planned, at 19 pm today (April 28 - Vietnam time), VINASAT-1 satellite will be moved to the fund position. 131 degrees, after reaching a height of 35,768km compared to the earth's surface last Friday, April 25.

Thus, after eight days from the time the satellite separated from the Ariane 5 rocket, the VINASAT-1 satellite had risen to the height of the geostationary orbit (35,768km) and moved to the location of the test orbit. is 131 degrees East. Next, according to Mr. Thong, "after testing all specifications in this position, from May 18 to May 20, VINASAT-1 satellite will be taken to the operational position of 132 degrees East."

This will be the position of "resident" trajectory of VINASAT-1 which has been registered by Vietnam for the next 15 years with the International Telecommunication Union ITU. Representative of VINASAT satellite manufacturer - Lockhed Martin also said: When the satellite enters the position of 132 degrees East in geostationary orbit, we will conduct a series of satellites, receivers and signaling, deployment of solar panels, . on satellites.

Ariane 5 rocket carrying VINASAT-1 leaves the launch pad at Kourou (South America) at 5:17 am April 19, Hanoi time.

Usually these tests last 3-4 weeks and the manufacturer will conduct with the staff of VNPT (VNPT) at the ground control stations.

Some sources believe that "on the first day of satellite launch, VINASAT-1 has" landed "at 129 degrees East" is not completely accurate. The reason is that the position of the "East" coordinates of VINASAT-1 here is interpreted as the longitude value of the satellite while at the height of the geostationary orbit (satellites do not move against the ground), while The latitude of the satellite is always zero because it lies on the equatorial plane.

When separated from the Ariane 5 rocket, VINASAT-1 only reached a height of 1,660.9km, and continued to use satellite thrusters to fly around the earth for 11 rounds in 8 days to reach the height of the fund. Static geography is 35,768km compared to the earth's surface.

On April 25, VINASAT-1 completed the flight to this altitude and successfully carried out antena and 2 solar panels. Due to the height of nearly 36,000 km, so from April 25 to this afternoon, April 28, VINASAT-1 moved to the position of 131 degrees East to conduct technical testing. After completing this process in a few weeks, VINASAT-1 will be moved to position 132 degrees East and fixed at this coordinates.

Currently, according to Mr. Thong, VINASAT-1 satellite is operating normally and stably and there is no problem in general. Satellites continually signal communications about Lockheed Martin's two ground control stations located in the US and Australia.

Two satellite control stations located in Vietnam are Que Duong station (Ha Tay) and Binh Duong station has also received signals from VINASAT-1.
