Field	Description	Range	Default
a	Minimum fix	2 or 3	3
b	Maximum PDOP	00-50	05
c	Minimum satellite count	03-24	03


>SCXCQ31004<
// a=3   → Minimum fix: 3D (more precise)
// b=10  → Maximum PDOP: 10
// c=04  → Minimum 4 satellites

PDOP (Position Dilution of Precision): Lower values indicate better satellite geometry. Recommended: ≤5 for high precision.


>SCXCQ30306<
// 3D fix, PDOP ≤3, minimum 6 satellites
// Ideal for avoiding false speed violation alerts
