Which statement accurately describes the difference between a track and a contact in BCC terminology?

• A. A track is a detected signal; a contact is movement data.
• B. A track is an instrument reading; a contact is a telemetry packet.
• C. A track is the ongoing location and movement data; a contact is a detected signal that may become a track.
• D. Track and contact are interchangeable terms.

Answer: (C)

In BCC terms, a contact is any detected signal indicating a possible object, but without enough data to define its movement or identity as a tracked entity. A track, on the other hand, is the ongoing set of location and movement data for a specific object, built from continuous observations that establish its course, speed, and track identity over time. So a contact may become a track once enough data exists to confirm consistent movement and identity. The difference isn’t about instrument readings or telemetry packets, and they aren’t interchangeable—one is a detection, the other is an established record of movement.
