If VINASAT-1 is designed with 20 active transponders, including 8 extended C-band sets, 12 Ku-band sets, with a bandwidth of 36MHz/1 set, 8 backup transponders (4 sets Ku band, 4 extended C band sets), VINASAT-2 is more “spectacular”, with 30 Ku band transponders (24 commercial operators and 6 backup sets).
Thus, it can be seen that VINASAT-2 has 4 more transponders than VINASAT-1, equivalent to 20% of VINASAT-1’s capacity. While VINASAT-1 has Ku band coverage in: Vietnam, Laos, Cambodia, Thailand and part of Myanmar, VINASAT-2 expands its coverage area with coverage of parts of Malaysia and Myanmar. With VINASAT-2, it can have a lifespan of up to 21.3 years.
VINASAT-1 can still operate for about 5 more years
A frequency expert shares with VietNamNet, even though the VINASAT-1 satellite has expired according to its design, this satellite can still last another 5 years of operation. However, preparing for a new satellite is an early issue because we cannot be sure when this satellite will stop operating.
“Normally, when bidding to buy satellite capacity, customers will require the satellite to have about 30% of its remaining usage time according to the design commitment. Therefore, this time will be difficult for VNPT – the unit operating VINASAT-1 and VINASAT-2, when bidding for satellite transmission services”, said the expert.
After successfully launching two satellites VINASAT-1 and VINASAT-2, Vietnam became the 7th country in the ASEAN region and realized the dream of having a position and sovereignty in satellite orbit.
The launch of the VINASAT satellite is particularly important in completing Vietnam’s telecommunications system, when previously there was radio information, wired information, ground information, sea surface information and now there is additional telecommunications satellites.
It has a proactive effect in connecting to remote areas, border areas, and islands that our country could not previously do with ground information systems.
This satellite will help Vietnam be proactive in ensuring national security and defense, especially tasks in border areas, islands and at sea.
Currently, the satellite market is experiencing fierce price competition among operators in the region.
