Bottom Track Commands
The Sentinel V RT system uses these commands for bottom-tracking applications. Bottom track com-
mands tell the Sentinel V RT to collect speed-over-bottom data and detected range-to-bottom data. If the
Sentinel V RT were facing UP, all bottom-track information would apply to the surface boundary instead
of the bottom boundary. The default state of bottom tracking is OFF (BP0) for Sentinel V RT systems. To
turn ON the bottom-tracking process, send a BP1 command.
