EDGE Microwave explains the evolution of GNSS signal modulations in its latest technical primer, offering defense and aerospace professionals a clear look at how modern satellite navigation achieves precision, resilience, and spectral efficiency.
Global Navigation Satellite Systems underpin mission-critical applications across defense platforms, secure communications, autonomous vehicles, and aviation. While GNSS receivers appear seamless in operation, the signal structures behind them represent decades of engineering advancement. Edge Microwave’s article walks readers through the progression from legacy BPSK-DSSS waveforms to advanced Binary Offset Carrier (BOC), Composite and Time-Multiplexed BOC (CBOC/TMBOC), and ultimately the highly sophisticated AltBOC modulation used in Galileo’s E5 band.
The primer outlines how direct-sequence spread spectrum improves ranging accuracy, strengthens interference resistance, and enhances multipath mitigation, all essential in contested or congested RF environments. It also highlights how modern waveforms achieve greater processing gain, spectral control, and built-in robustness without expanding bandwidth requirements.
For defense engineers, system integrators, and RF specialists seeking a concise yet technically grounded overview of GNSS waveform design and modernization trends, this article provides valuable context.
