Key Trends in Satellite Communication

Today, various aircraft can provide high-speed internet connectivity. Similarly, unmanned aerial vehicles (UAVs) and high-altitude platforms are interesting candidates for optical communication system applications.

FREMONT, CA: Military and defense applications, broadband IP services, and ground- and space- segment products and services are expanding rapidly in the satellite environment. In the previous decade, these technologies have achieved substantial breakthrough efficiency and performance increases. However, these enhancements have occurred along with significant performance gains by other telecommunications and information technology systems.

Trends in Satellite Communication

  • Data Transmission from Observation Satellites: Several observation satellites have been designed to continuously watch the Earth in order to probe the environment and forecast weather. These satellites have onboard space radio stations that collect data and broadcast it back to Earth via feeder lines.
  • Internet Broadband Service to Space Planes and Aircraft: Today, various aircraft can provide high-speed internet connectivity. Similarly, unmanned aerial vehicles (UAVs) and high-altitude platforms are interesting candidates for optical communication system applications.
  • Communication within the Clusters of Satellites: The services that are typically performed by a single large satellite can be distributed among multiple interconnected and co-located smaller spacecraft. Each satellite may be allocated a particular role, but the cluster as a whole would work as one massive satellite. Maintaining safety boundaries within colocation slots requires maneuvering synchronization and cooperative control. Monitoring and control systems for LEO satellites are managed via the connection provided by GEO satellites.

Data Transmission Using Deep Space Probes: Because the power, volume, and mass of the onboard equipment in deep space missions are highly constrained, so are the transmission power and antenna diameter. A high-power transmitter and a large reception antenna are typically installed in the ground station to compensate for the onboard constraints.
