Uplink Downlink

The VSAT Uplink Downlink Simulator with Python is a professional tool for modeling satellite communication links. It simulates both uplink (earth station to satellite) and downlink (satellite to earth station) paths, incorporating ITU‑R standards for accurate attenuation and propagation analysis. With customizable parameters such as frequency, antenna size, polarization, and transmit power, users can evaluate link budgets, carrier‑to‑noise ratios, and overall system reliability.

Built in Python, the simulator offers flexibility, scalability, and graphical outputs for clear visualization. It is ideal for engineers, researchers, and educators working in satellite communication, RF engineering, and telecom industries. Whether you are designing resilient VSAT networks, conducting academic research, or training students, this simulator provides a powerful environment to understand and optimize uplink and downlink performance.
