The Japanese multinational consumer electronics company Sony Group Corporation has also become a major player in the aerospace industry and announced that its subsidiary Sony Corporation of America (SCA) has created a new company, Sony Space Communications Corporation (SSC), to implement satellite optical communications.
Currently, there are approximately 12,000 satellites in space, and the number is expected to increase in the future. The amount of data used in orbit is increasing year by year, but the amount of radio waves available is limited.said Kiyohe Iwamoto, President of Sony Space Communications Corporation. “LEO satellites need to communicate with the Earth, so a lot of communication facilities are needed for real-time communication, which is a problem because these satellites have to pass directly over a ground station to communicate with them. In addition, The need for radio frequency licenses and lower power consumption requirements for communications equipment compared to smaller satellites such as microsatellites are also issues that need to be addressed.”
To solve these problems, SSC plans to develop small optical communication devices To provide services related to linking small satellites in low Earth orbit through a laser beam.
SSC wants to provide this optical communication equipment as a service to companies engaged in the development of satellites. By using optical communications, SSC aims to achieve high-speed communications with small devices, which is actually difficult to achieve with traditional wireless communications because conventional communications require a large antenna and high power output.
also, By building an optical communication network not only between satellites and the Earth, but also between satellites in orbitSSC aims to enable real-time communications from anywhere on Earth to any satellite in space. Optical communications are easier to implement than traditional wireless communications, because they do not require the specific types of licenses that wireless communications require.
By providing easy-to-use communications capabilities between satellites, SSC aims to increase the amount of communications in space And the creation of a network of Internet communications covering land and space and applications such as real-time services.
