Since this is a more-likely and less-expensive way to disable satellite capability, the primary focus should not be on protecting satellites in space, but on increasing security and defenses for satellite ground stations and mitigating jamming by the use of encryption, antijamming equipment, and "frequency hopping," which avoids interference from jamming on a particular frequency by switching to a new one after transmitting or receiving a packet of data.
