HIGH FREQUENCY RADIOTELEX (SITOR) AMVER AND OBS SERVICE DISCONTINUED FROM COAST GUARD CAMSLANT AND COMMSTA KODIAK
The Coast Guard will terminate high frequency (HF) radiotelex (SITOR) services from Communications Area Master Station Atlantic (CAMSLANT -NMN) and Communications Station Kodiak (NOJ) used for the collection of AMVER ship position reports and of meteorological observations effective 2400Z March 31, 2008. HF radiotelex services from Communications Area Master Station Pacific (CAMSPAC - NMC/NMO) and Communications Station Guam (NRV) will continue until at least September 30, 2008.
AMVER and NOAA meteorological reports will continue to be received at no charge through ShipCom HF radiotelex (NBDP) service via stations KLB near Seattle, WA, and WLO near Mobile, AL, and NOAA's SEAS (Shipboard Environmental (data) Acquisition System) program through Inmarsat C. AMVER reports may also be sent at no charge through Globe Wireless. Broadcasts of maritime safety information by HF SITOR (HF NAVTEX) will not be affected by this action.

AMVER, or Automated Mutual-assistance Vessel Rescue, is used to report ship positions to Rescue Coordination Centers. The discontinuation of reporting via HF-SITOR reflects the obsolescence of HF-data systems which have now been replaced by E-mail via Satellite communication services. We could estimate that it may not be too long before Narrow Band Direct Printing (NBDP) goes away completely, even for GMDSS and Safety of Life at Sea. The CAMS still monitor for Distress calls via HF NBDP. However, if ship’s crew no longer use HF-SITOR for daily reporting of AMVER and Meteorological data, we could surmise they will soon lose all skills required to send an urgency message with it also.
A new system of ship reporting, Long Range Information and Tracking system (LRIT), which entered into force on January 1, 2008, does not become mandatory for all ships until the phase-in sometime after December 31, 2008. LRIT will probably not replace AMVER since LRIT is required only to a maximum of 1,000nm from any country’s shoreline. For almost all country’s vessels, AMVER reporting is mandatory at least once per day. The meteorological reports included are voluntary.
