Generate GNSS Waveform

Generate multi-satellite GNSS baseband waveforms with properly encoded navigation data. Channel impairments (Doppler, delay, noise) can come from a realistic satellite scenario OR from user-specified custom values. Supports GPS, Galileo, and NavIC constellations. The waveform carries real ephemeris so a receiver can decode it for position estimation.

When to Use

• Generating GNSS baseband signals (GPS, Galileo, or NavIC) for receiver testing
• Simulating multi-satellite channels with Doppler and delay from orbital dynamics
• Testing with specific Doppler/delay/SNR values (custom channel mode)
• Building end-to-end GNSS receiver simulations that need decodable nav data

When NOT to Use

• Signal acquisition, tracking loops, nav decoding, or position estimation
• BeiDou/GLONASS (not supported) or SDR hardware transmission
