Umbilical
The umbilical is the backbone of the
NAVIC
system. It provides all power, network
distribution as well as encoder signal transmission. Circuitry is incorporated into the
umbilical to protect or isolate all signals. The umbilical provides separation between
the user’s instrument, power supply and the crawler. Various umbilical lengths are
available from 5 m to 30 m
(16.4 ft to 98.4 ft)
long.
