VINASAT-1 was put into use for the first time

Yesterday, 22/5, VNPT put VINASAT-1 into use for the first time, with the transmission of standardized signals from 2 ground stations in Hanoi and Ho Chi Minh City to satellites.

According to VNPT, this is an important procedure for VNPT to affirm to the World Telecommunication Union (ITU) that Vietnam has put VINASAT-1 into stable and timely operation as required by ITU.

In the afternoon of May 22, 2008, immediately after Lockheed Martin completed the technical handover to VINASAT-1 VNPT satellite, VTI's technical staff in Hanoi, Ho Chi Minh City and Que Duong Satellite Control Station ( Ha Tay) has deployed transmission equipment, ready to wait for a coordinated signal from Lockheed Martin's control station in the US

From 21h50 'Vietnam time (ie 15h50 GMT) on May 22, 2008, the International Telecommunication Center of Region I in Hanoi has started to carry out standard signal transmission (video and sample) on channels K1, K3, K6, K7, K9, K12 on satellites, corresponding to the Ku band Ku-band transponders of VINASAT-1.

The signal spectrum on the monitor screens shows that the carrier carrier (no-load transmitting signal) and the modulation carrier (data transmission with data) are standard.

These important parameters were also shown on the monitor screen of Lockheed Martin and Que Duong Station; and was printed by VTI's technical staff, faxed immediately to Lockheed Martin for comparison, and for ITU to report the results.

Meanwhile, starting from 19:00 on the 22nd of May, the International Telecommunications Center of Region II in Ho Chi Minh City has also started to transmit standard signals on C1, C5, C11 and C4 channels. C8, C12 on satellites, corresponding transponders on VINASAT-1 C band.

According to VNPT, the first signal transmission to VINASAT-1 was successful and met the standard as expected. After just over an hour (until 23h10 ') the work is complete.

Thus, up to this point, the progress of implementing the first project on launching satellite telecommunications in Vietnam has ensured the plan. ITU's request to bring the VINASAT-1 into operation and use before May 23 has also been fully implemented by VNPT.

Currently, Lockheed Martin still leaves 4 technical experts at Que Duong Station to support VTI during the VINASAT-1 satellite control.
