Viasat实时空间中继
Intersatellite communication leveraging Viasat's advanced space, ground, and networking infrastructure for real-time, 全局数据传输
Viasat enables real-time data links through intersatellite communication
也称为“交联”," intersatellite communication allows satellites in a constellation to link to one another and relay data in space. Since small satellite constellations in low Earth orbit (LEO) are not in constant contact with the ground, intersatellite links allow data to be shared between adjacent satellites. Viasat offers several types of crosslinking solutions, including Ka-band and two types of V-band using a phased array antenna. By placing a miniature modem and router on each satellite, the constellation can have full transmit and receive capability for real-time data links.
Cost-effective data relay capabilities for LEO operators
许多卫星, 或者太空飞行器, operating in LEO routinely collect data, such as Earth and weather observations, radar measurements and other science data, that must be sent back to Earth in real-time. In choosing how to transport this data back to Earth for analysis and distribution, satellite operators often must consider a tradeoff between data latency, the time between data collection to when it is received back on Earth, and cost. 为了克服这个问题, Viasat is developing a space relay capability that is intended to give LEO operators the ability to send data — in real-time, from all around the globe — over the planned ViaSat-3 geostationary orbit (GEO) network.
Leveraging the combined power of our satellite fleet, real-time earth, and networking solutions
Viasat's innovative space relay solution combines our leading-edge space technologies, 地面系统, 以及网络能力, aimed at enhancing communication for near-Earth space users and supporting satellite operator needs. This comprehensive approach is designed to deliver high throughput capabilities, 确保安全, reliable, and scalable connections for data transport. Our solution includes turnkey advanced space terminals that provide a complete suite for accessing our sophisticated constellation network. Coupled with our extensive real-time Earth ground station network spanning 6 continents, we enable satellite operators to efficiently manage, downlink, and swiftly distribute data from GEO, LEO, 和MEO卫星. This ensures timely and secure real-time streaming to any designated endpoint, reinforcing our commitment to facilitating superior space-to-space communications.
Expanding horizons with InCommand
As part of Viasat's commitment to pioneering advancements in space communication, we introduce "InCommand" – a service designed to seamlessly integrate with our space relay system. InCommand enhances our intersatellite communications by providing an additional layer of flexibility and control for Low Earth Orbit (LEO) satellite operations. InCommand works in tandem with our Real-Time Space Relay (RTSR) system, offering a robust solution for on-demand satellite command and control. 这项服务确保持续, near real-time communication with GEO satellite infrastructure, facilitating rapid tasking and data transmission for LEO satellites. InCommand's dynamic bandwidth allocation and low latency capabilities make it a game-changer for satellite operators seeking efficient and reliable space-based command and control.
