Satellites convey by utilizing radio waves to convey messages to the receiving wires on the Earth. The receiving wires then, at that point, catch those transmissions and cycle the data coming from those transmissions. As we probably are aware satellite correspondence utilizes satellites set over the earth for correspondence by VSATs put on the earth. A satellite or bits Earth when its speed is balanced by the pull of Earth’s gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds, and along different paths. It is likewise utilized for TV broadcasting. Satellites use microwave frequencies for correspondence with one another utilizing satellite connections and with earth stations or VSATs. Earth Observation and Imagery. Satellites can give a picture of the outer layer of the Earth. Correspondence Satellites can empower correspondence administrations on the ground.
The Bangabandhu Satellite-1 (Bangabandhu-1) is the primary Bangladeshi geostationary interchanges and broadcasting satellite. It is named after the father of the nations, Bangabandhu Sheikh Mujibur Rahman. It was made by Thales Alenia Space and sent off on 12 May 2018. The satellite was the primary payload sent off by a Space X Falcon 9 Block 5 sendoff vehicle. The task is being carried out by Bangladesh Telecommunication Regulatory Commission (BTRC) working inseparably with US-based Space Partnership International, LLC. The public authority claimed Bangladesh Satellite Company Limited, BSCL (Formerly known as Bangladesh Communication Satellite Company Limited, BCSCL) was framed determined to work the satellite. Bangabandhu-1 was planned and fabricated by Thales Alenia Space. The all-out cost of the satellite was projected to be 248 million US dollars in 2015. The satellite conveys 40 Ku-band and C-band transponders with a limit of 1600 megahertz and an anticipated life expectancy to surpass 15 years. The satellite was at first wanted to send off on 10 May 2018. Nonetheless, the rocket conveying the payload set off a programmed cut short as it entered interior power and control at T-58 seconds. The rocket sendoff was pushed back 24 hours, and it was at long last sent off on 11 May 2018. The satellite purposes ground control stations worked by Thales Alenia Space with its accomplice Spectra’s essential ground station in Gazipur. The optional ground station is at Betbunia, Rangamati. The principal test signal after sendoff was gotten by the administrators on 12 May 2018.
How beneficial has the first satellite been?
Bangabandhu-1, the first satellite of Bangladesh, was launched into orbit on May 12, 2018, and went into trial transmission on September 4 the same year. Bangabandhu-1 began commercial operations in May 2019 and earns Tk 10-11 crore each month from agreements to rent transponders of the satellite to local TV channels. Although the income is sufficient to maintain the satellite and operate the BSCL office, it had been expected to be more profitable.
The main reason the satellite has failed to earn more is it is yet to attract foreign buyers, as the international satellite bandwidth market is extremely competitive. However, BSCL is still trying to convince buyers in the Philippines, Nepal, and other nearby countries, according to officials.
The government has started plans to send off the nation’s second satellite around three years after the main arrived at circle. Bangabandhu-2 is supposed to send off in 2023, as per government sources.
Dissimilar to Bangabandhu-1, which was a correspondences satellite, Bangabandhu-2 will be a Low Earth Orbit (LEO) perception satellite. Therefore, it will be custom fitted toward ecological checking, meteorology, map making, and guard purposes. It is planned for the new satellite to be used to monitor the vast maritime territories of Bangladesh and surrounding countries, as well as the country’s land borders with India and Myanmar. The satellite can likewise be valuable to anticipate and get ready for streak floods, as water races to the streams in the northern and north-eastern transboundary slopes of Bangladesh from nearby slopes in India in the pre-storm season, between April and May.
Likewise, a huge area of yield fields the nation over can be checked with the satellite, to shield developing harvests from bugs like grasshoppers.
