A compass locator is called a compass locator when used in conjunction with which?

A compass locator is a low‑power non-directional beacon that works with the ILS marker beacons to mark the approach path. When a locator is used together with the ILS marker system (outer, middle, or inner markers), it’s referred to as a compass locator. This naming highlights its role as part of the ILS marker family, rather than as a separate distance/navigation aid like DME or TACAN.
