Mobile Networks of Sensing Systems:

1
Mobile Networks of Sensing Systems toward an
Interagency Glider Consortium
Oscar Schofield, Mary Jane Perry, Dan Rudnick
2
Mobile platforms have matured since the original
DEOS committee and the subsequent birthing of OOI
and ORION. Potential integrating technology.
Critical for revolutionary advances.
All coastal arrays required significant mobile
sensing systems to resolve the horizontal and
vertical variability. RCO also specifies mobile
sensing networks. Global buoys require context
that can be provided by mobile networks.

High resolution spatial time series is now

Spatial time series are now
Temperature fluctuations w/in pycnocline are
dominated by offshore propagating signal, similar
to transport signal

Partners? NAVO plans to purchase on the order of
100 Gliders over next decade because of planned
needs and demonstrated capabilities
Satellite data only
NAVAL GOALS
Tuned Parameters. Satellite and 4 gliders
LBSFI Transforms the warfighters ability to
leverage environmental Battlespace Awareness for
smart asset / sensor placement and operational
effectiveness end-to-end integration of
in-littoral sensors into FORCEnet, including
cohesive, net-centric information flow to
tactical users.

Development of an ONR Glider consortium In brief
Goal is to expand glider expertise, usability,
availibility for ONR researchers. To be
facilitated by a centralized institution (still
to be determined) that manages ONR gliders being
acquired by three technical centers. Each center
has a fleet of specific gliders.
Overseen by APL (N. Bogue)
Webb Gliders (Rutgers)
Spray Gliders (Scripps)
Sea Gliders (UW)
These are ONR assets will be available to support
ONR experiments. Analogous to UNOLs asset.

Global Command and Control Relatively Robust
11
Goals also include improving improve and
standardize command control (ease Navy
transition), procedures for lithium batteries
(handling etc.), improved ship operations,
training and transition

For ORION?
-ALPS has had three organizing meetings (San
Diego, Paris, Stevensville) yet is still
developing its funding home. -ORION should
leverage of existing efforts. How? How best to
entrain the program managers or should a group
go write to compete for more ORION assets (2
million was initial ONR investment in glider
fleets for the technical centers)? NOPP? PI
alone? MSI? -ONR is currently less likely to
loan assets, however is likely to be amenable to
partnering. Might an ONR model provide a useful
model for ORION researchers? Might existing
consortia be expanded at lower costs?

Action Items

• A ORION white paper of steps forward for mobile
  assets to be available at the DI workshop
• Finish the mobile asset web portal for ORION web
  site
• Continue to build ONR collaborative partnership
