Figure 2.1 DSM 132 receiver
As part of a marine construction or survey system, the receiver
provides submeter (less than 3.28 ft) precision whenever differential
corrections are applied. You can use a 1 PPS (pulse per second) strobe
signal to synchronize time for logging event markers when you are
using external instruments.
You can use the receiver with a variety of marine survey equipment,
including office software such as HYDROpro™, which also interfaces
with echo sounders and magnetometers, for use on waterborne
projects.
