Absolutely required is the capability of turning off the transmitter.  See RR 22.1 and RR 25.11.

RR 22.1	Space stations shall be fitted with devices to ensure immediate cessation of
their radio emissions by telecommand, whenever such cessation is required under the provisions
of these Regulations.

RR 25.11	Administrations authorizing space stations in the amateur-satellite service
shall ensure that sufficient earth command stations are established before launch to ensure that
any harmful interference caused by emissions from a station in the amateur-satellite service can
be terminated immediately (see No. 22.1).

I hope this helps.
