Satellite Communication: Emerging Trends and Developments to Know in 2023

In the past, ground cabling carried most of the communication, but now it is aided by satellites, especially geostationary models, providing almost continuous and complete coverage.

Fremont, CA: Defense and military applications, broadband IP services, and space-segment products and services are mushrooming in the satellite space at an incredible pace. During the last decade, these technologies have achieved significant breakthroughs in efficiency and performance. Despite these advancements, other telecommunications and IT systems have seen vast performance gains as well.

In the day-to-day world of communication, satellites play an essential role

Despite the fact that some people aren't aware of it, most daily communications are done through satellites, not ground cables. In the past, ground cabling carried most of the communication, but now it is aided by satellites, especially geostationary models, providing almost continuous and complete coverage.

Satellite communication trends

• Transmitting data from observation satellites: Many observation satellites have been developed to continuously monitor the Earth for probing the environment and forecasting weather. Satellites equipped with space radio stations transmit data back to Earth via feeder links after collecting data.

• In deep space probes, the power, volume, and mass of onboard equipment are strictly limited, and so are the transmit power and antenna diameter. The ground station is generally equipped with a high-power transmitter and a large receiving antenna.

• In satellite clusters, the functions that are typically performed by one large satellite can be delegated to several smaller satellites that are interconnected and co-located. The satellites may have different functions, but on the whole, this cluster would act as one big satellite. In order to maintain safety boundaries within colocation slots, maneuvering synchronization and cooperative control are crucial. Satellite monitoring and control systems are controlled by GEO satellites via connectivity.

Satellite communication advancements face a major challenge in latency

Satellite communication faces the challenge of latency - delays caused by switching and distance. The issue isn't relevant for broadcasts or web browsing, but it is important between consumers who are only a few miles (say 3,000 miles) apart as an aircraft flies (but 70,000 miles apart if the signal bounces through a satellite). For surgeons who control robotic operating equipment during surgery in another country, it can be quite annoying, especially during video conferences. In addition, satellite communication is not suitable for the ADAS domain due to the need for very low latency.

Communication via satellite in the future

In science, forecasting the future is uncertain. There is, however, a trend in the satellite space towards ever greater flexibility, capacity, and service availability, as well as lighter, more compact, more affordable, and ergonomic devices.
