Nimiq 4 has two payloads for Canadian broadcast services. The main payload will provide specialty television and foreign language programming. The second payload has six beams covering Canada for such advanced services as high-definition television. Nimiq satellites are dedicated to the provision of direct-to-home services for Bell TV.

•Anticipated service life: 15 years
The Proton M launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the Nimiq 4 satellite on board. The first three stages of the Proton will use a standard ascent trajectory to place the Breeze M fourth stage and the Nimiq 4 satellite into a suborbital trajectory from which the Breeze M will then place itself and the spacecraft into a low Earth circular parking orbit. Once Nimiq 4 is in the parking orbit, it will be injected into a geosynchronous transfer orbit following four additional burns of the Breeze M.
