Elon Musk’s Space X hopes to make money primarily from these Starlink satellites: its launch vehicles to reach the International Space Station or the moon or Mars are expensive, infrequent projects.Ĭan satellite internet be affordable? That depends on the volume of traffic. Starlink relies on thousands of satellites. The trouble with communication via LEO satellites is that you require hundreds, if not thousands, of such satellites for the job - the closer they are to earth, the faster they whiz around, and have to bounce their signals off a number of satellites to reach the intended destination of the originating signal. When a signal has to be bounced off a satellite thousands of km away, it creates latency, whereas LEO satellites cause little latency. Geostationary satellites are placed nearly 36,000 km away from the planet, while LEOs are anywhere between a hundred to a thousand km above earth. The modern, satellite-based internet connectivity has low latency - latency is the time elapsed between initiation of an action and its taking effect - unlike old-school satellite-based internet, thanks to reliance on satellites close to earth, in low-earth orbit (LEO). Connection by V-SAT is primitive compared to offerings by Starlink, OneWeb and the like. It should be recalled that satellites with very small apertures (V-SATs) have been providing internet connectivity since the 1990s - several bank ATMs and ITC’s e-chaupal functioned on the basis of V-SAT linkage. It makes sense to make use of satellite-based broadband, to enable remote parts of India’s vast expanse to go online. Clearly, the terrestrial route to universal internet access will take quite some time more - India has more than 600,000 villages, apart from thousands of towns. Of these, Wifi has been set up, as per the official website, in 104,293 panchayats, but wifi is active in only 53,600 locations. This is how you lose tax benefits on health policiesįailing multiple deadlines, and renamed BharatNet in 2015, the project continues, and claims to have reached 187,245 panchayats.
