ACM
ACM (Adaptive Coding and Modulation) is a technology used in satellite communications to make signals more reliable regardless of weather conditions. Think of it like a smart radio that automatically adjusts its settings based on conditions - similar to how your car's automatic transmission shifts gears depending on whether you're going uphill or downhill. When bad weather affects satellite signals, ACM helps maintain the connection by changing how information is sent, ensuring that important communications stay working. This is particularly important for businesses that rely on constant satellite connections for their operations.

Example Interview Questions
Senior Level Questions
Q: How would you design a satellite communication system that optimizes ACM for maximum efficiency?
Expected Answer: A strong answer should discuss analyzing weather patterns, setting up monitoring systems, and creating backup plans for different scenarios. They should mention experience with different types of satellite systems and how to choose the right settings for different customer needs.
Q: What considerations are important when implementing ACM in a large-scale satellite network?
Expected Answer: Look for answers that discuss managing multiple ground stations, coordinating with different teams, understanding customer requirements, and having experience with different weather conditions and their effects on signals.
Mid Level Questions
Q: Explain how ACM helps maintain signal quality during rain fade conditions.
Expected Answer: They should be able to explain in simple terms how the system detects poor weather conditions and automatically adjusts settings to maintain the connection, with examples from their experience.
Q: What tools do you use to monitor ACM performance?
Expected Answer: Should be familiar with common monitoring systems and be able to explain how they track signal quality and system adjustments over time.
Junior Level Questions
Q: What is ACM and why is it important in satellite communications?
Expected Answer: Should be able to explain that ACM helps maintain reliable connections during bad weather by automatically adjusting signal settings, even if they don't have hands-on experience yet.
Q: What are the basic components of an ACM system?
Expected Answer: Should understand the basic parts: monitoring equipment, control systems, and how they work together to maintain signal quality.
