// Sample of Yankee Actual Training Materials

This page is a condensed excerpt from the GNSS waveform reference issued to students in Yankee Actual's EW operations training programs. The complete reference covers every signal across all seven constellations — carriers, modulation, spreading codes, bandwidths, and SDR capture guidance — and is provided as part of course materials.

02 — In the Complete Training Reference

Every signal, every constellation — 25+ signals including military, restricted, and new-generation CDMA signals.
Modulation & spreading parameters — chip rates, code structures, data rates, and navigation message formats for receiver and monitoring work.
Bandwidth planning tables — spectral occupancy by modulation family, with receiver front-end selection guidance.
SDR capture guidance — practical multi-constellation monitoring strategies used in Yankee Actual course labs.
