Question: How is Position LSB from Table 9 computed?
Answer:
Minute of an arc, or arc minute, is a unit of angular measurement. One arc minute is defined as one-sixtieth of a degree
(1/60 degree). Table 9 refers to one complete rotation or 360 degrees.
Computing the arc minute in Table 9: 360 / 2^N (where N is the resolution)
- If 10 bits will be used, Arc min is: 360 / (2^10) = 0.3516 degrees
- Converting to Arc min: 0.315 degrees x [60 min / 1 degree] = 21.1 min
