# USE OF GPS FOR ELECTRONIC POSITION FIXING

In the Federal Register dated March 23, 1994 \[59 FR 13757-59\], the
U.S. Coast Guard announced that Global Positioning System (GPS)
receivers met the carriage requirements for electronic position fixing
devices as required in Title 33, Code of Federal Regulations, Part
164.41(a)(2) \[33 CFR 164.41(a)(2)\]. Because of the number of inquiries
regarding the use of GPS for position fixing, we are readvertising this
item of interest. Copies of the Federal Register notice are available
from the Coast Guard's Navigation Center:

Internet (http://www.navcen.uscg.mil/gps/ggeninfo/IOC-CAR.TXT);

# OMEGA RADIONAVIGATION SYSTEM TERMINATION

The Coast Guard intends to terminate its involvement in the worldwide
Omega Radionavigation System on 30 September 1997. This will include
closure of the two stations located in the U.S. (Lamoure, North Dakota
and Haiku, Hawaii) and termination of the existing bilateral agreements
with the six partner nations (Argentina, Australia, France, Japan,
Liberia, and Norway).

The Omega navigation system primarily serves aviation and weather users.
The Department of Transportation recently completed its review of Omega
navigation requirements and notified the U.S. Coast Guard that most
users will complete their conversion to Global Positioning System
technology by September 1997.

For further information contact Mr. Stewart Shoulta, Radio Aids Division
(G-OPN-3), U.S. Coast Guard Headquarters, 2100 Second St. SW,
Washington, D.C. 20593-0001, or phone (202) 267-6052.

LNM 44/96 dated 29 October 1996.

dGPS USER SAFETY ADVISORY

The Coast Guard Navigation Information Service (NIS) recently received
reports of dGPS receivers apparently ignoring the broadcast alarm which
should signal the immediate discontinuation of a particular satellite
correction. In accordance with international and industry standards
\[RTCM SC104\], the USCG dGPS broadcast sets a satellite correction to
the defined "do-not-use" value of 10485.76 meters if broadcast integrity
checks indicate there is a problem with that satellite's correction.
Reports indicate some user equipment does not properly recognize this
"do-not-use" correction flag and instead erroneously processes it as a
correction. This can result in position errors as large as 15,000 meters
while the receiver is in dGPS mode. Users should contact the
manufacturer of their equipment immediately to determine if they require
a receiver upgrade.

LNM 44/96 dated 29 October 1996.

# SHIP ROUTING STUDY

A two year ship movement study is currently in progress for the Naval
Air Warfare Center, Point Mugu Sea Test Range. This study is being
conducted to determine the amount and type of shipping traffic
transiting the Sea Test Range (STR). Information obtained from
participating vessels will be utilized to determine the frequency of
transit and most frequently utilized transit routes. Results of the
study may be used to enhance the safety of all vessels transiting
through or maneuvering within the STR and to formulate the most
advantageous transit routes that least impact missile firing operations.
Vessel cooperation and assistance is requested in this effort by asking
that the following information be provided prior to entering the STR:

A. Vessel name, flag and radio call sign,

B. Vessel type and gross tonnage,

C. Vessel engine type and type of fuel used,

D. Last port of call/Next port of call,

E. ETA at Sea Test Range and ETD from Sea Test Range,

F. Route through the STR (N, S, E or W)

Vessels are requested to contact PLEAD Control on 5081.5 Hz (5080Hz) or
3238.5 Hz (3237Hz). Commercial/cellular phone (805) 989-8841. Prior to
arrival on the STR or when leaving port, the above information may also
be faxed to Mr. S. Robinson at (805) 488-3582.

LNM 21/95 dated 23 May 1995.

DISCREPANCY REPORTS OF THE MARINE d-GPS

The U.S. Coast Guard is in the Initial Operational Capability (IOC)
phase of the marine dGPS service. During IOC, the dGPS service is
available for positioning and navigation. However, users are always
cautioned to use all available navigation tools to ensure proper
evaluation of position solutions. During this IOC phase, system
validation tests are being conducted, procurement and installation of
the next generation of transmitters is being pursued, the control
station software is being upgraded, and other problems identified during
the pre-operational and IOC phases are being resolved.

To facilitate the evaluation and development of the final dGPS service,
reports of dGPS discrepancies are highly beneficial. To ensure timely
and complete information, user discrepancy reports are required in the
following format:

A. Date of Report

B. Reporting Source

C. Reporting Source Phone Number (Day/Night)

D. Reporting Source Position/General Geographic Location

E. Date/Time of Event

F. Duration of the Occurence

G. Reporting Source Activity

H. Environmental Conditions (Weather)

I. Bearing and Range to Electrical Storm

J. DGPS Broadcast Site Used

K. Type of DGPS Receiver Used

L. Problem DGPS Receiver Indicated

M. Other Receiver Indications

N. DGPS Beacon Signal Strength Observed

O. DGPS Beacon Signal to Noise Ratio Observed

P. Does Receiver Operate Correctly With Other DGPS Sites

Q. Does Receiver Function Properly in GPS Mode of Operation

R. Comments

## Monterey Bay National Marine Sanctuary

California - Central Coast - The Monterey Bay National Marine Sanctuary,
the largest by volume of its kind in the country, includes over 5000
square miles of coastal and ocean waters off the central California
coast. It spans over 300 miles of coastline from Cambria to Point Reyes,
and extends as much as 50 miles offshore. The area was given sanctuary
protection in recognition of its dramatic underwater geology and
topography, its floral and faunal diversity, its abundant and distinct
commercial fishery, and its standing as an important research site.
Monterey Bay itself supports diverse bird species and several endangered
marine mammals, including the California gray whale, humpback whale, and
the California sea otter.

Virtually all vessel types, including tankers, container ships, towing
vessels, fishing vessels, and recreational craft, currently transit the
sanctuary. Though most tankers voluntarily remain 50 miles or more
offshore during their coastal voyage, most other commercial shipping
transits closer to the coast.

When engaged in transit of the central California coast, all vessels
carrying oil or hazardous materials as cargo, or those carrying large
volumes of bunker fuel, are urged to transit as far from shore as
weather and operations permit, and in any event navigate with particular
caution, with due regard for the devastating consequences of spilled oil
in the Monterey Bay National Marine Sanctuary. 2
