Our Low-Earth Orbit (LEO) Telecommunication Satellites spin around the Earth at 575 km altitude, completing an orbit every 90 minutes. These space birds deliver total coverage to the planet. From pole-to-pole, each Telecommunication can transport hundreds of GB every day for any customer, providing superior connectivity for the most demanding needs.
ATB Telecommunication custom-built software-defined radio (SDR) is an ultra-high-throughput communications payload that enables great flexibility in ATB’s service offering.
It allows us to quickly setup hardware for launch and then constantly improve the Telecommunication’s capabilities with software updates — something that would be impossible with hardware radio solutions. With this radio, ATB can use the same hardware to support customers with many different data needs.
- Dynamically adjust channel bandwidths and data rates
- Use a wide variety of telecommunication protocols for different applications
- Modify center frequency to ensure non-interference with other networks
ATB launched and operates the first commercial Ku-band LEO Telecommunication.
Ku-band (10.7 - 12.7 GHz for transmit and 14.0 - 14.5 GHz for receive) is substantially higher than traditional nanosatellite frequencies, which are often around 2 GHz for bi-directional communications. This offers increased available bandwidth to support larger data applications.
A sophisticated antenna array is necessary at these higher frequencies. An antenna array is made up of many smaller antenna elements that, when combined, create a high-gain and highly directed radiofrequency beam.
The way LEO constellations work is simple. Our satellites are launched into space and placed into Low Earth Orbit at around 575 km from Earth.
Since LEO satellites are located closer to Earth (less than 2,000 km from the planet), latency is significantly reduced compared to geostationary satellites at 35,000 km from Earth.
Being closer to Earth results in better signal strength and this means less power is required for transmission compared to the big GEO satellites, which experience significant signal loss due to their distance from the planet
Our LEO satellites are placed into a polar orbit, meaning they orbit over the poles. A single Telecommunication can see the entire planet, but a large number of satellites are needed to provide a continuous and real-time communications service.
