MBARI ocean observing systems (MOOS)
New mooring controller
Lead Scientist: Jim McFarlane and Francisco Chavez
Lead Engineer/Project Manager: Bob Herlein
The New Mooring Controller proposal is a continuation of the 1999
project of the same name. The 1999 project was approved to start in July
of 1999 as a two year project. The goal is to replace the existing OASIS
The OASIS mooring controller has been in service since January 1992. It
has been successful in supporting data collection to study the
biogechemistry of Monterey Bay (M1, M2, M3), mullti-institutional
shipboard experiments (IronEx 1 & 2, COOP cruises, ShiftUp cruises),
and deployed on the TOGA/TAO array for opto-biological and chemical
measurements (EqPac 1 & 2).
However, the OASIS hardware and software is quickly becoming obsolete
and unsupportable. We have only 8 controller boards remaining. The boards
are old and showing wear in their mechanical and electrical interfaces.
There are numerous circuit modifications which are fragile and subject to
failure in harsh environments. The software is equally old, built from
software tools that havenít been updated in years.
This project has primary and secondary goals. The primary goal is to
replace the existing functionality supported by the OASIS controller,
using modern hardware and software tools and techniques. It will use the
StrongArm processor developed by Radochonski which will presumeably become
the core processor for new instrumentation at MBARI and for MOOS. The
software will use the VxWorks operating system, as used on Tiburon and for
the Nav processors on the Western Flyer and Pt Lobos, and will use object
oriented techniques similar to the application frameworks used by OíReilly
on Tiburon and Cline on Genosensor. In summary, the primary goal is to
replace existing functionality with modern components and tools.
The secondary goal is to coordinate with the Instrumetation Software
Infrastructure project and with MOOS, to serve as an incremental
development toward the larger software architecture being proposed for
MBARI. In this context, we would like to experiment with forward-looking
software design techniques, such as CORBA and distributed-object network
architectures, in order to be a first step towards the architecture being
developed for MOOS. Note that this is a secondary goal, subject to
delivery of primary goals and limitations of resources.
