Old rules for sharing satellite radio frequencies are getting a refresh from US regulators

The US communications regulator is asking for public input on new technical rules for how satellites share radio frequencies. These rules define how many satellites can operate in the same orbital space without interfering.

The current technical rules for sharing radio frequencies in geostationary orbit are based on older satellite technology. This means newer, more efficient satellite systems might be limited by outdated definitions. Updating these rules could allow more satellites to operate in the same orbital space, or let existing ones use their spectrum more effectively.
