PART 1 - INTRODUCTION
1.1 SYSTEM OVERVIEW
The Hydra and Hercules Pilot fully integrate with, and complement the
Hydra 2000, Hercules 2000 and HS2000 Instrument Systems, both in
terms of style and performance. The Instrument System transmits
sensor information via the B&G FastNet Data cabling to the Pilot
Computer Unit. A typical Pilot System is shown in Figure 1.1.
The Pilot Computer processes the sensor data and then sends
signals to the rudder driving system (linear ram, rotary drive or
hydraulic pump) to steer the vessel on the desired course. The
complex learning algorithms (a form of artificial intelligence) used in
the Pilot Computer, ensure that the steering performance is optimised
regardless of the weather conditions, and quickly responds to any
changes that may occur.
Control of the Pilot is via the keys on any one of the dedicated Pilot
displays. Each display acts as a master allowing control of the Pilot
from any station.
The Hydra and Hercules Pilot are essentially the same. Both Pilots are
available with a wide range of powerful and reliable 12V or 24V dc
rudder drive units suitable for boats of over 7m (23ft). The control
electronics (the Autopilot Computer) are supplied as ACP1 or ACP2
(Advanced Control Programming) depending on the size of vessel,
power requirements and options that have been selected and fitted.
The Hydra Pilot can be used for both sail and power boats that have a
Hydra 2000 or HS2000 System installed. The Hercules Pilot can only
be used in boats with a Hercules 2000 System installed.
If the relevant sensor data is available, both systems offer the
following Steering Options:
(a) Steer to Compass - Uses data from the Pilot or
Instrument Compass to maintain the selected compass
heading.
