Disclaimer: This tool provides an educational approximation of satellite radio link performance. Real-world results depend on antenna patterns, local noise floor, satellite orientation, Doppler correction, tracking accuracy, feedline installation, receiver performance and operational factors. It should be used for learning and rough planning, not as a guarantee of contact success.
