To avoid any signal interference, the microsatellites to be tested will at times reduce the Ku transmission power or at times quit Ku downlink emissions entirely, it said. The company in its filing also clarified its collision avoidance plan, saying it would work with the Joint Space Operations Center on cataloging satellites before launch and making orbital parameters available to it. SpaceX's proposed satellite tests in advance of a low earth orbit constellation providing a global broadband service have seen pushback from Intelsat, because that company has raised concerns about Ku-downlink interference and collision risks (see 1509110013).
