Inter Satellite Service Empowers Future Communication Systems

Inter-satellite service is revolutionizing the way we communicate, and it's about to get a whole lot better. This innovative technology enables satellites to communicate directly with each other, reducing reliance on ground-based infrastructure.

With the ability to share data and resources, inter-satellite service is empowering future communication systems to be more efficient, reliable, and secure. This is especially important for remote or disaster-stricken areas where traditional communication systems may be compromised.

Inter-satellite service is also paving the way for new applications and services, such as high-speed internet and advanced weather forecasting. By leveraging the capabilities of multiple satellites, we can unlock new possibilities for global connectivity and information exchange.

Optical Communications is a game-changer for inter-satellite service. It offers faster and more reliable data transmission compared to traditional radio frequency (RF) communications.

NEC's goal is to build an optical communication network system that uses their optical inter-satellite communication technology. This system will enable faster inter-satellite communications with a higher capacity and increased coverage for data transmission.

Optical inter-satellite communications use high-frequency carrier waves and large bandwidth, making it possible to achieve high-speed and high-capacity communication. This is a significant improvement over traditional RF communications, which have limited bandwidth and are prone to interference.

The use of optical antennas is also a major advantage, as they can be smaller and lighter than RF antennas. This weight reduction is a great benefit, as launch costs are greatly reduced.

However, optical inter-satellite communications require high accuracy pointing, acquisition, and tracking technology for communication links. This is a significant challenge, but it also provides an additional layer of security.

NEC has developed optical transponders with amplifiers and modems that can operate in the space environment. These transponders use a high-power optical amplifier (EDFA) to ensure high power characteristic and long-term reliability.

The inter-satellite transfer rate of NEC's laser communication terminal is 1.8 Gbps, which is at the world's top level and more than seven times faster than conventional radio wave communications. This is a significant achievement that will enable faster and more reliable data transmission between satellites.

Optical inter-satellite communications will play a crucial role in supporting the sophistication of optical communication networks, such as multiple access. This will enable smaller, lighter, and faster transmission rates, making it an essential technology for future satellite constellations.

NEC's laser communication terminal employs the 1.5 µm band wavelength, which is widely used in underwater cables and LANs and also has excellent parts availability. This is a significant advantage, as it will make it easier to maintain and repair the system.

NEC aims to improve the ability to transmit data immediately from satellite observations, which is becoming increasingly large in volume. This is achieved through a data relay system that enables faster inter-satellite communications with a higher capacity and increased coverage for data transmission.

The wavelength used for NEC's optical inter-satellite communication technology is 852 nm, and the power is 15 mW. This is powered by a DFB laser diode.

Satellite constellations are being built in iterations, with one or a handful of first-generation systems launching, followed by the next generation. This process is driven by the need to improve on previous designs, cost-effectively, while balancing consistency.

Optimizing channels, communications frequency, transponder use, amplification and modification, and other aspects of the satcom chain is essential for engineering tomorrow's service expectations.

Emerging pLEO networks offer several benefits, including low-latency data transmission and global coverage. However, they present new technical challenges, especially in network architecture, design, and protocols.

Satellites can autonomously communicate and maneuver to avoid collisions, ensuring orbital safety.

This is made possible by inter-satellite links (ISLs), which enable satellites to exchange data and coordinate their actions in real-time.

Orbiting satellites can identify space debris and broadcast data on it to nearby satellites, allowing them to adjust flight paths or operations accordingly.

Systems communicating on congested bands may be able to re-route or manage their data exchange using satellite cross-links to contact the ground.

Satellites can communicate on, and work to mitigate, system errors, failures, and even space weather effects, via cross-linked communication back-ups.

Multiple satellites can make and utilize coordinated ranging measurements of debris or other operational satellites without ISL technology, and communicate the results to the ground or other systems.

Satellites that are in contact with the ground can receive data on debris or traffic and then pass this on to others that are not reachable at the time, or to systems in other orbits, cis-lunar, or deep space.

A constellation of satellites with ISLs can act as a backup network for all aspects of sustainability related data exchange, enhancing knowledge about the orbital environment in real-time for operators everywhere.

Here are some key benefits of ISL technology in ensuring orbital safety and connectivity:

NEC aims to improve the ability to transmit data immediately from satellite observations, which is becoming increasingly large in volume, so that it can then be applied to various fields.

This goal requires a data relay system that enables faster inter-satellite communications with a higher capacity and increased coverage for data transmission.

To achieve this, NEC plans to build an optical communication network system that uses their optical inter-satellite communication technology.

Optimizing channels, communications frequency, transponder use, amplification, and modification, and other aspects of the satcom chain is crucial for engineering for tomorrow’s service expectations as well as today’s mission requirements.

Satellite constellations are built in iterations, with one or a handful of first-generation systems launching and, if profitability or operational stability is achieved, the next generation is then engineered.

Small companies dedicated to developing a genuinely sustainable commercial service will look to use every opportunity to improve on previous designs, cost-effectively and while balancing consistency.
