Which of the following are provided by satellite tracking programs?

• A. Maps showing the real-time position of the satellite track over Earth
• B. The time, azimuth, and elevation of the start, maximum altitude, and end of a pass
• C. The apparent frequency of the satellite transmission, including effects of Doppler shift
• D. All these choices are correct

Answer: (D)

Satellite tracking programs are designed to provide a wide range of information related to satellites in orbit, making them essential tools for amateur radio operators and space enthusiasts. The first option highlights that these programs can generate maps that display the real-time position of satellites as they travel across the Earth. This is crucial for users who need to establish communication or perform other tracking-based activities. The second option outlines the specific details regarding a satellite's pass over a given location, including the times for when the satellite starts rising, reaches its maximum altitude, and sets. It also includes the azimuth (the compass direction from which the satellite is coming) and elevation (how high it is in the sky), which is critical for aiming antennas and optimizing signal reception. The third option refers to the apparent frequency of the satellite's transmission. Due to the Doppler effect, which causes shifts in frequency depending on the relative motion of the satellite and the observer, tracking programs can provide accurate information about these frequency changes. This data is important for operators to tune their receiving equipment correctly to maintain optimal communication. By offering real-time tracking, precise timing and positioning information, and frequency details that account for Doppler shift, satellite tracking programs encompass all the features mentioned in each of the individual choices.
