It tells you: • How many satellites were being used and which ones. • DOP (Dilution of Precision) values — which affect accuracy. • The GPS time and week when you started and stopped the measurement. • Any warnings or corrections that were active during the survey. • Think of QC1 as a snapshot of the conditions during measurement (like weather for flying — not the flight itself). ________________________________________ 🔹 QC2 – The Math Behind the Scenes QC2 gives you the technical stats from the RTK engine: • It shows the Variance-Covariance Matrix (VCV) — this tells you how precise and reliable the coordinates are, especially how much the X, Y, Z components might vary or relate to one another. • It includes an Error Scale and Unit Variance (which are more technical but help assess overall quality). • If QC1 is the weather, QC2 is the engine performance report of the flight — full of behind-the-scenes math. ________________________________________ 🔹 QC3 – The Shape of the Error QC3 presents the information in a more visual or practical format: • It converts the VCV matrix into an error ellipse — showing you how much uncertainty there is in each direction (North, East, Up). • Includes Sigma values (how much error to expect in each direction), semi-major/minor axes, and ellipse orientation. • Great for visualizing how accurate your point is and in which direction the error might stretch. • Think of QC3 as a map of your uncertainty — the “shadow” of possible error around your point. ________________________________________ ✅ TL;DR QC Level What it Tells You Analogy QC1 Satellites, time, signal quality (basic GNSS info) Weather during the flight QC2 The raw math: variances in X/Y/Z (VCV matrix) Engine diagnostics QC3 Visual shape of position error (error ellipse) Where the plane might drift
