Small Vessel Tracking/Monitoring (panel 7)
Relevant National/Local Initiatives (Partial)
• National/DHS and Local Small Vessel Strategy Working SessionsNext: Feb 8-9, Miami
• Multi-agency, J-HOC, Seahawk, et al
• NOAA VMS/LEADS
• Potential Port of Long Beach/DHS Pilot Project

Control… Gov’t/LEA Commissions/Registers Devices, Unlike AIS
Vessel Owner/lessee Owns Device - Dual-use, e.g., - Abated-rate Insurance - Panic Button Call-for-aid - Fewer Boardings, Preferential Routes - Affordable – Encourage Voluntary Participation - $0 Recurring Wireless Service Cost – No Public Carrier - Gov’t Annual Registration Fee

KEY TECHNOLOGIES; Drivers:Cost, Registry-Assurance
GOV’T (LEA) COMMISSIONED? COMMENT
1. Consumer Device NO No Authentication; Cellular costs
2. AIS-B NO Costly Transponder; No Authentication MMSI # Not Controlled For Anti-rogues
3. Marine VHF/GPS NO No Authentication; Channel clutter
4. Active Radar Beacon w/ID(e.g., low cost periodic RACON)
TBD Immature Technology ; Uncertain CostUSCG Radar- Avoid Certification Impact
5. “Choke-point” Low Power RF(Harbor Entrance)
YES, but No ID/Track Within Harbor – key issue1,000-2,000 Ft. Not Viable w/ISO-RFID, But …Has been shown viable w/IEEE 802.15.4 w/RF Obstructed By Alongside VesselEstim. Qty. Cost: $25
6. Harbor-wide/offshore w/GPS YES VHF MURS w/SOTDMA; No FCC license Self-deactivate if de-installed; black-boxEstim. Qty. Cost: $100 Gov’t owned Infrastructure – trivial cost
#4 If R&D Proves Viable: High-payoff – But Must Be Non-proprietary, Standards-Based#5 Is Lowest Cost; Lacks Crucial In-harbor Movement Info. (Where’s it now?)#6 Higher but Viable Cost; Likely Best, Long Term

#4 “Choke-point” Validation Tests w/IEEE 802.15.4 Devices + High-gain Ashore Antennas (2)
2,000 ft. Width
w/Alongside small/large vessels - Good, but not fool-proof
#6, Harbor-wide/offshore; VHF/MURS + MURS
Typ. IEEE 802.15.4 Tag Bi-directional, encrypted
Miles of Range
Coverage Harbor-wide + Offshore To anchorage, Few Low cost RF Modems w/VHF Gain Antennas
Data to/from Ops center via existing Port Authority networks
Validation From Prior Projects Using MURS At Similar RF power. Simple to Confirm
Typ. VHF/MURSBi-directional, encrypted

TAKE-AWAY’s
•Encrypted Over the Air Commissioning By LEA/agent• Silent Alarm if Unauthorized De-installed (attempt to move to another vessel)
• Choke Point Scenario: Using Active Tags (IEEE 802.15.4) Technically Viable, but…
• Guidance On Harbor-wide vs. Choke-point-only: Is Choke-point Inadequate?
• Harbor-wide VHF GPS Device - Gov’t Owned Infrastructure (low cost) – • Most Prudent?• Standardize for Use CONUS and Cooperating territories, and At-scale cost benefit
• Suggested: Initiative Yielding Non-proprietary & Secure Low Cost RACON (#4)
• Assumption OK? Registration Fee Subsidizes Cost Of Adequate On-Boat Device
• Standardize/Nationalize Locale-Collaborative Registry w/Revocation and Watch Lists
