Netsat — virtual satellite receiver in the browser

Learn to receive and decode satellite signals without buying SDR hardware

Problem

Receiving and decoding satellite signals is one of the coolest radio projects, but the learning curve is steep: protocols are complex, signals are hard to catch and track, and you must invest in equipment just to start. Many people give up before getting started.

Solution

An internet-streamed virtual satellite signal that simulates the SDR receiving experience in the browser: view the spectrum, tune frequency and gain, watch signal acquisition and decoding, with simplified DSP tutorials and step-by-step missions.

Users

Beginners, students, and amateur radio enthusiasts interested in radio and DSP.

MVP

In-browser virtual SDR interface; pre-recorded or simulated satellite signal stream; frequency and gain controls; signal acquisition and decoding demo; step-by-step getting-started tutorial.

Revenue

Free basic scenarios plus paid advanced satellite and tutorial packs, one-time purchase or subscription.

Why now

SDR hardware is cheaper but still an investment, and virtualization lowers the entry barrier. Web Audio and WebAssembly make in-browser DSP feasible, so a solo developer can build this cheaply.
