The consumer terminal dismantling of SpaceX company Starlink internet constellation found it sharing chip suppliers with apple.The terminal, called Dishy Mcflatface, is used to connect users to Starlink satellites in orbit, which then forward user data to SpaceX ground stations to communicate with Internet servers.

According to Kenneth keiter's analysis video on youtube, these terminals have their own application processors and radio front-end units. Both chips are made by STM, and STM is also responsible forAppleProvided by the companyiPhoneandiPadIt is famous for its components. Kenneth Keiter said the two chips were designed to run satellite antenna software and enable its antenna to generate the right signals to communicate with orbiting satellites. The Italian Semiconductor introduced MPU microprocessors in 2019, based on a 32-bit Arm Cortex A series of kernels, using a Cortex M4 kernel designed for digital signal control applications.

At present, Italian semiconductor has listed 12 MPUs based on the core for sale. There are two choices of single core and dual core, with the frequency of 800MHz and 650MHz. Among these 12 models, SpaceX is likely to use stm32mp151a / C or stm32mp153a / C derivatives. The difference between mp153 and mp151 series is that the former adopts can FD (controller area network flexible data rate) data communication protocol. As can FD is developed for automobiles and is mainly used in automobiles, SpaceX is likely to use the customized version of mp151 series for SpaceX.

The report quoted an insider as saying that the details of SpaceX's semiconductor manufacturing agreement with Italy and France were shared. According to the details, the company may have paid terminal manufacturers up to $2.4 billion to build one million user terminals. According to insiders, the unit price of the end-user terminal has been set at about $2400. If it is true, it will take quite a long time for SpaceX LLC (a Starlink subsidiary of SpaceX company) to achieve positive bottom line profit. The loss incurred by SpaceX due to these terminals will be accounted for through the company's operating profit from the service. Elon Musk said in May that launching a batch of 60 satellites would cost about $15 million.
