DAP-1
Navy Surface Combatant
Sensor Network Challenges
Dave Phillips7 October 1999
DARPA Sensor IT Workshop
DAP-2
Technology Requirements Driven By New Ship Development Program Objectives
Highly Capable, Multi-mission Affordable Survivable Reliable Maintainable & Sustainable Interoperable Flexible Upgradeable Maintain High Quality of Life for the Crew Environmentally Friendly
DAP-3
Why Do We Need Networked Sensors?
Need to Answer the Questions Is everything OK? What is happening? Are my corrective actions working? Will equipment fail before mission completion?
Typical Measurements Needed in Ship Spaces (machinery and open space) Temperature Smoke/Gases Water/Fluids Noise Light/RF
Vibration/Shock Stress/Strain Movement Others
DAP-4
Networked Sensor Vision
Many Sensors Within Space
Wireless Connections with Access Point on Shipwide LAN
Tied to Actuators
“Smart”
Replicated in Each Space
DAP-5
Affordability Challenges
Non-Recurring Engineering Minimized
Leverage COTS and commercial system development
Low Recurring Costs
Thousands of sensors per ship
Inexpensive sensors, processing units
Easy to install/ remove
• Minimal or no wiring
Low Operating and Support Costs
No maintenance (e.g., battery replacement)
Automatic test and calibration
DAP-6
Survivability Challenges
Sensors Must Survive
Normal ship environment
Catastrophic events when data is most needed to assess and monitor space or machinery
• Fire
• Flood
• Explosion
Willing to Trade Reliability Against Cost Provided Redundancy and Coverage Can Be Accomplished at Higher Level
• Shock
• Others
DAP-7
Other Challenges
Scaleable
Architecture must accommodate few to many sensors
Open
Sensors should connect to network using open standards
Upgradeable
Sensors should be easily upgraded as sensor technology evolves
Environmentally Friendly
Safe in normal and during catastrophic events
DAP-8
Summary
Many Challenges to Networked Sensors in Surface Ships
Other Platforms Have Similar Challenges
Cost is Challenge Number One
Have a Very Successful Workshop!
