Aireon Does Canadian Validation Testing of ADS-B System

Aireon and Canadian civil air navigation system operator Nav Canada ran one of two planned validation test flights of a satellite-based automatic dependent surveillance-broadcast (ADS-B) system, Aireon said in a news release Wednesday. Along with that March flight, Aireon said it also did validation flights in March with Polaris Flight Systems and the Federal Aviation Administration (see 1704260047). Aireon said it expects its satellite-based ADS-B system to be operational in 2018, after the completion of the Iridium Next constellation.
