Mahmood aforesaid, guests can ought to be among 5 kilometres from the launch pad to visualize the take-off with their own eyes. The satellite can stay visible for around seven minutes.
“The 3.7-tone satellite can travel vertically up to thirty six,000km from the launch pad before creating changes for orbit and it'll intermit days for that,” project Director Mezbahuzzaman additional.
The launch method has 2 phases. the primary is that the Launch and Early Orbit section (LEOP) and therefore the second section is Satellite in Orbit. The LEOP section can take ten days whereas the second can take twenty days.

After the satellite becomes active its management can shift to 3 ground stations within the America, Italia and Korean Peninsula. “The 3 stations can take hold of the satellite and move it 300km to its allotted position (119.1 east longitudinal orbital slot),” Mezbahuzzaman aforesaid.
It will take regarding twenty days to bring the satellite underneath complete management. Once it's fully operational, the management are going to be transferred to the bottom stations in East Pakistan, Mahmood additional.
The Falcon-9 rocket, has four elements, with the satellite on high, followed by the device. Below the device is Stage-2 of the rocket, whereas the bottom section is Stage-1.
“During take-off Stage-1 can fireplace and can carry the craft upwards with tremendous speed,” the project director aforesaid. when taking the satellite to acceptable elevation, the Stage-1 rockets can break loose and fall back to earth, change on the Stage-2 rockets.
Stage-2 can carry the craft to thirty five,700km before being jettisoned and can linger in orbit at a particular distance from the satellite, he added. it'll take few a lot of days to tame the satellite at its Gazipur’s Joydebpur and Rangamati’s Betbunia ground stations.
Bangabandhu-1 has forty transponders, one admire 36MHz spectrum. consistent with the arrange, East Pakistan can use twenty transponders. The twenty differents are going to be rented resolute other countries particularly in some South East Asian countries like Philippines and Indonesia.
