To get better precision when geo-referencing, it’s useful to precisely calculate the unique azimuth for each point by
accounting for the firing timing. These precision azimuths may be calculated/interpolated using the timing offsets shown in
Figure 9-7 on page 65
and
Figure 9-8 on the previous page
.
Consider a single data packet with 12 data blocks. The azimuth given at the beginning of each data block represents the
azimuth reported at the moment the first pair of lasers in the block fire. If you assume the rotational speed is constant over
