Final answer:
Traffic counts at satellite fields should be reported by air traffic controllers, who are responsible for monitoring aircraft and maintaining safe airport operations.
Step-by-step explanation:
The traffic count at satellite fields (OLF's, ALF's) should be reported on a separate control tower sheet by air traffic controllers. The significant responsibility of an air traffic controller includes monitoring and guiding aircraft, whether in the air or on the ground, to ensure safe operations within an airport's airspace and on the runways. Therefore, they are the ones who have the firsthand information regarding traffic count and the authority to report it accurately.
