On Tuesday, the founder and CEO of elsk musk Technology Co., Ltd. may share more than $2.5 million with its friends outside the US space circle, according to the report of elsk musk Technology Co., Ltd. < / 3 > > on Tuesday < p > < / P > < p > If 250000 people use the star chain network, given that the monthly fee for the service is $100, it means that SpaceX's revenue will reach $25 million per month, equivalent to $300 million per year. And this is calculated according to the lower number, because musk said its user terminals "exceed" 250000 < p > musk said on Twitter: "there are more than 250000 star chain user terminals." I'm not sure what he means. But most likely, musk means that these terminals are being used, but it may also refer to the number of user terminals manufactured by the company so far < p > SpaceX currently has nearly 2000 satellite chains in orbit. The hard cost of each launch of satellite chain is about US $15 million. Assuming that 50 satellites are launched each time, the launch cost of each satellite alone is about US $300000. This brings the hard cost of launching the existing star chain network to $600 million, which means that SpaceX will recover this cost within two years according to the current customer level < p > of course, there are many other costs, including ground station, R & D, satellite loss and so on. Moreover, the cost of $100 per month is not all profit, which can not be used to offset the cost of satellite manufacturing and launch. However, star chain Internet service is becoming a real business. Over time, more customers will continue to help amortize the company's costs at a faster speed < p > in addition, SpaceX recently announced a faster and higher bandwidth service, Starlink premium, for enterprises in remote areas, which will bring more revenue. The company said delivery of the service would begin in the second quarter of this year. It is reported that the cost of this service is $500 per month. (small) < / P > < p >
