Which of the following are provided by satellite tracking programs?

• A. Real-time weather data
• B. Maps showing the real-time position of the satellite track over Earth
• C. Historical communication logs
• D. Orbit decay predictions

Answer: (B)

Satellite tracking programs are designed to monitor the positions of satellites as they orbit Earth, offering valuable insights into space operations and communication. The correct choice reflects the fundamental function of these programs, which is to provide maps or visual representations that illustrate the current trajectory and position of satellites over the Earth's surface.

These maps are essential for users who need to know when a satellite is passing overhead, which is crucial for optimal communication and data reception. The ability to visualize a satellite's position in real-time aids operators in coordinating satellite communications, whether for personal use, scientific research, or commercial purposes.

While real-time weather data, historical communication logs, and orbit decay predictions might be related functions and are important in their own right, they do not directly address the core purpose of satellite tracking programs. Thus, maps showing the real-time position of the satellite track over Earth represent the primary and most relevant output of these programs, aligning perfectly with their operational goals.
