What's New at RTCM
What do you see when you step onto the bridge of a modern ship or well-equipped boat?
Chances are that RTCM standards and RTCM activities had a lot to do with the communication and navigation equipment there.
In the United States, the Federal Communications Commission and U.S. Coast Guard use RTCM standards to specify radar systems, Emergency Position Indicating Radio Beacons, and the basic version of Digital Selective Calling radios.
Personal Locator Beacons used on land in the U.S. are required to meet an RTCM standard.
RTCM standards are used internationally for Differential Global Navigation Satellite Systems and Electronic Chart Systems.
RTCM members also have the opportunity to monitor and participate in the development of international standards for maritime radiocommunication and electronic navigation systems.
The Radio Technical Commission for Maritime Services (RTCM) is a 501(c)(3) international non-profit scientific, professional and educational organization.RTCM members are organizations (note individuals) that are both non-government and government. Although started in 1947 as a U.S. government advisory committee, RTCM is now an independent organization supported by its members from all over the world.
We keep our members involved on regional and international maritime radionavigation and radiocommunication policy issues, regulatory changes, and technical standards development.
Our Special Committees provide a forum in which government and non-government members work together to develop technical standards and consensus recommendations in regard to issues of particular concern.
We are actively engaged in the development of international standards for maritime radionavigation and radiocommunication systems through our involvement in:
We also contribute to the relevant work of:
RTCM has over 130 member organizations, including:
RTCM Special Committees are chartered to address in-depth radiocommunication and radionavigation areas of concern to the RTCM membership. The output documents and reports prepared by these Committees are usually published as RTCM Standards. Special Committees are chaired by a subject expert, appointed from an RTCM member organization. All RTCM member organizations are eligible to participate in any Special Committee activity. Participation may be both by correspondence (usually E-mail), and through attendance at meetings. Special Committee output documents in the form of RTCM Recommendations have been widely accepted for both voluntary and mandatory use, and the Special Committees routinely update the Recommendations to reflect ongoing changes in technology. Current Special Committees include:
Special Committee (SC) 101 on Digital Selective Calling (DSC)
Special Committee (SC) 104 on Differential Global Navigation Satellite Systems (DGNSS)
Special Committee (SC) 109 on Electronic Charting Technology
Special Committee (SC) 110 on Emergency Beacons (EPIRBs and PLBs)
Special Committee (SC) 112 on Ship Radar
Special Committee (SC) 117 on Maritime VHF Interference
Special Committee (SC) 119 on Maritime Survivor Locator Devices
Special Committee (SC) 121 on Automatic Identification Systems (AIS) and Digital Messaging
Special Committee (SC) 123 on Digital Message Services over Maritime Frequencies
Special Committee (SC) 127 on Enhanced Loran (eLoran)
Special Committee (SC) 128 on Satellite Emergency Notification Devices (SEND)
Special Committee (SC) 129 on Portrayal of Navigation-Related Information on Shipboard Displays
Special Committee (SC) 130 on Electro-Optical Imaging Systems
Special Committee (SC) 131 on Multi-system Shipborne Navigation Receivers
Special Committee (SC) 132 on Electronic Visual Distress Signalling Devices
Special Committee (SC) 133 on Data Exchange for Navigation-Related Applications for Mobile Devices
Special Committee (SC) 134 on Integrity for High Accuracy GNSS-Based Applications
Special Committee (SC) 135 on Radio Layer for Real-Time DGNSS Applications
RTCM also has a number of subject-specific interest groups which are not currently developing or maintaining RTCM standards. These include:
Mailing List (ML) 107 on Maritime Safety Information Dissemination
Mailing List (ML) 120 on High Speed Craft
Mailing List (ML) 122 on Ship Security Alert Systems
Mailing List (ML) 124 - Maritime HF Users Interest Group
Mailing List (ML) 126 - Voyage Data Recorders
The current technical standards developed by the Special Committees include:
RTCM Recommended Minimum Standards for Digital Selective Calling (DSC) Equipment Providing Minimum Distress and Safety Capability, Version 1.0 (RTCM Paper 56-95/SC101-STD)“ This standard is referenced in the regulations of the U.S. Federal Communications Commission and defines minimum functions for DSC transceivers used in the U.S.
RTCM 10150.0 Standard for VHF-FM Portable Marine Radiotelephone Equipment with Digital Selective Calling (DSC) and Global Navigation Satellite System (GNSS) Location Function
RTCM 10402.3 RTCM Recommended Standards for Differential GNSS (Global Navigation Satellite Systems) Service, Version 2.3“ This standard is used around the world for differential satellite navigation systems, both maritime and terrestrial.
RTCM 10403.3, Differential GNSS (Global Navigation Satellite Systems) Services - Version 3 - A more efficient alternative to RTCM 10402.3

The RTCM Annual Assembly Meeting and Conference, which is open to both RTCM members and non-members, is structured to provide attendees with an overall update on the changing world of maritime radiocommmunications and radionavigation. The program includes a series of paper presentations, panel sessions, workshops, and RTCM Special Committee meetings dealing with issues of current concern to the maritime community. Other organizations such as the International Electrotechnical Commission (IEC), the National Marine Electronics Association (NMEA), the U.S. National GMDSS Implementation Task Force, and the NOAA SARSAT Beacon Manufacturers Workshop, also typically hold meetings in conjunction with the RTCM Assembly. All attendees are invited to participate in all sessions. Through the cooperation of RTCM members exhibitors, latest technology providing radiocommunications and radionavigation equipment capability capabilities and services are on display.
RTCM is chartered in the District of Columbia, USA, as a 501(c)(3) non-profit scientific and educational organization, focusing on all aspects of maritime radiocommunications, radionavigation, and related technologies. Founded in 1947 as a U.S. State Department advisory committee, it is now an independent non-profit membership organization. RTCM standards are incorporated by reference into U.S. Federal Communications Commission and U.S. Coast Guard regulations. They have been used as the basis for requirements in standards of the International Electrotechnical Commission (IEC), which are now mandatory under Chapters IV and V of the International Convention for the Safety of Life at Sea (SOLAS).
