Published purpose

The availability of high-speed Internet, including in the underserved areas of Canada's northern and rural regions, will be greatly improved with proposed Low Earth Orbit (LEO) communications satellites. These satellites will use wider bandwidth radio signals than existing geosynchronous satellites, in a challenging environment that includes additive white noise, time-varying path delay, loss and Doppler frequency shift, and other propagation effects. The objective of the project is to design and implement a platform that simulates LEO satellite channel impairments, as seen by a terminal frequently switching between satellites in order to maintain a communications path. By emulating the effects on the wideband radio signals, the satellite radio test system will allow developers to test their technologies under realistic conditions in a controlled lab environment before launch. The test platform will ensure that solutions providing broadband services to a large number of users are reliable, and capable of meeting the demanding requirements for applications such as remote backhaul, secure low latency end-to-end communications, and high-speed Internet access.
