Nimiq-3, -4i and -4iR

Nimiq-3 and Nimiq-4i were leased by Bell Satellite TV from DirecTV Inc. when they were already in orbit. Originally called '' Direct-TV3'' and ''Direct-TV2'' respectively, these Hughes HS-601 models were brought out of retirement and are currently used to share some of the workload from ''Nimiq-2'' and ''Nimiq-1'', respectively. They went online in Bell TV's stead in 2004 and 2006. Nimiq-4i ran out of fuel and was replaced by Nimiq-4iR on 28 April 2007.
