* - GPS: 1-32
* - SBAS: 120-151, 183-192
- * - GLONASS: Set the upper 8 bits, signed, to the frequency channel number
- * (FCN) in the range from -7 to +6, if known, and -127, if
- * unknown
- * Set the lower 8 bits, signed, to the orbital slot number (OSN)
- * in the range from 1-24, if known, or -127 if unknown
- * At least one of the two (FCN & OSN) must be set to a known
- * value
+ * - GLONASS: 1-24, the orbital slot number (OSN), if known. Or, if not:
+ * 93-106, the frequency channel number (FCN) (-7 to +6) offset by + 100
+ * i.e. report an FCN of -7 as 93, FCN of 0 as 100, and FCN of +6 as 106.
* - QZSS: 193-200
* - Galileo: 1-36
