NEC’s technology

Satellites carry out missions in the harsh environment of space. What kind of technology do they have on board? And how are satellites made? Let’s take a closer look.

LUCAS Inter-Satellite Optical Communication System

Linking Earth observation satellites and optical data relay satellites through optical communication enables the collection and rapid transmission of large volumes of data. What are the advantages of relaying data in space?

The satellite building process

Once a satellite is launched, it cannot be repaired. To endure the harsh environment of space—a near-vacuum environment with extreme temperature fluctuations—and successfully carry out missions over the years, robust monozukuri (i.e., the Japanese art of manufacturing) is crucial. Click on the links below to learn about the meticulous attention the NEC Group pays to detail in the manufacturing and assembly of satellites as well as the various satellite tests it performs in environments simulating outer space.

Vibrations during launch, supersonic shocks, and harsh thermal environments… What tests must satellites pass to complete a space mission?

Technologies supporting satellites

How can satellites far from Earth complete their missions? How do we operate satellites that cannot be repaired for years? Keep reading to find out more about the technologies that support these satellites.
