Key Trends in Satellite Communication

Data Transmission Utilizing Deep Space Probes: Because the volume, power, and mass of deep space probes' onboard equipment are strictly limited, the transmit power and antenna diameter are also limited.

Fremont, CA: Military and defence applications, broadband IP services, and ground- and space- segment products and services are all expanding at a rapid pace in the satellite space. In the last decade, these technologies have achieved significant breakthrough efficiencies and performance improvements. However, these advancements have occurred concurrently with significant performance gains by other telecommunications and information technology systems.

Trends in Satellite Communication

• Data Transmission from Observation Satellites: A number of observation satellites have been developed to continuously monitor the Earth in order to probe the environment and forecast weather. These satellites have on-board space radio stations that collect data and transmit it back to Earth via feeder links.

• Data Transmission Utilizing Deep Space Probes: Because the volume, power, and mass of deep space probes' onboard equipment are strictly limited, the transmit power and antenna diameter are also limited. To compensate for the onboard limitations, a high power transmitter and a large receiving antenna are typically installed in the ground station.

•  Communication within Satellite Clusters: Functions that are typically performed by a single large satellite can be delegated to a network of interconnected and co-located smaller satellites. Each satellite could be assigned a different function, but the cluster as a whole would function as one massive satellite. Maintaining safety boundaries within colocation slots requires manoeuvring synchronisation and cooperative control. Monitoring and control systems for LEO satellites are managed using connectivity provided by GEO satellites.
