Global Maritime Thechnology

What Global Maritime Thechnology does

Global Maritime Technology ((주)지엠티, "GMT") is a Seongnam, South Korea-based maritime ICT company founded in 2002 that designs and supplies integrated surveillance, navigation, and security systems for maritime, aviation, land, and offshore-energy domains. Its core technology fuses radar, AIS (Automatic Identification System), VHF communications, CCTV, V-Pass (UHF fishery tracking), and e-Navigation/S-100 ECDIS into a proprietary K-series platform stack: K-RVET (GPU-based radar tracking of 2,000+ targets), K-MSIS (multi-sensor fusion of 10,000+ vessels with sub-3-second latency and dead-reckoning trajectory prediction), K-VTOS (200,000+ real-time target operations display), K-VTRS (ML-trained data playback and automatic voice-to-text transcription at up to 64x speed), K-VHF (multilingual Korean/English/Chinese/Japanese VHF synthesis), and K-VEIS (remote monitoring). Four end-to-end solutions are marketed: Integrated Maritime Situation Control, Maritime Traffic Control, Offshore Wind Farm Control, and Smart Berth (Apron) Control. GMT also sells standalone hardware including ECDIS, INS, e-Nav, V-Pass, AIS base stations and shipboard terminals, ISCS integrated ship communication terminals, and fishery distress beacons. The company claims #1 domestic market share in Korean maritime safety and security ICT, supported by quantified system performance (100,000+ simultaneous maritime objects) and operationally validated since 2005-2009 through maritime safety solution certifications.

GMT sells almost exclusively to government and institutional customers through direct enterprise sales and government procurement processes, with no public pricing. Its customer base is concentrated across Korea's maritime, defense, law enforcement, customs, intelligence, fisheries, port, and maritime transport safety agencies (e.g., Korea Coast Guard, Republic of Korea Navy, Republic of Korea Army, Ministry of Oceans and Fisheries, Korea Customs Service, National Intelligence Service, Korea Maritime Safety Tribunal, Korea Maritime Transportation Safety Authority, Busan Port Authority, Nonghyup Fishery Cooperative, Korea Rural Community Corporation, National Police Agency), the Korea Shipping Association, and the International Maritime Organization (IMO); the company has cited the Philippine Coast Guard as an overseas reference. Revenue is generated through hardware sales (navigation, communication, fishery safety equipment), software and systems integration (maritime control platforms), and professional services (consulting, implementation, maintenance). GMT maintains four office locations (Pangyo HQ, Sejong, Busan, and an Incheon manufacturing facility in Songdo Smart Valley), lists 11-50 employees, and is led by Representative Director Moon Byung-wook (문병욱). The company began international expansion and entered new business areas (aviation, offshore wind, land) from 2020 onwards and remains privately held with no disclosed external funding rounds.

Partnerships span international defense primes and technology providers (Thales, Saab, ASELSAN, Hanwha Systems, LG CNS, KT SAT, Siqura, ViNotion, Otonom Teknoloji, Microflown Maritime, CNS Systems, ITI, SRDC, NanoBiz, Daeyang) and a Korean R&D/university network that includes ETRI, the Korea Hydrographic and Oceanographic Agency, the Korea Research Institute of Ships and Ocean Engineering, the Korea Hydrographic Survey Association, the Korea Institute of Maritime and Fisheries Technology, Korea Maritime and Ocean University, the National Radio Research Agency, and multiple other national universities. International research collaboration is referenced with Eindhoven University of Technology. The company has been recognized with the 2020 Korea Industry Award (ICT/SW Category) from Money Today for maritime ICT delivery to the Korea Coast Guard and Navy, and the 2019 Youth-Friendly Strong Enterprise designation from the Ministry of Employment and Labor for workplace standards.

Core offering

GMT develops and sells integrated maritime ICT platforms that combine AIS, radar, VHF, CCTV, and V-Pass sensor data into real-time vessel traffic management, maritime situation control, and coastal/offshore surveillance systems. The company also produces standalone navigation equipment (ECDIS, INS, e-Nav), communication equipment (AIS, ISCS), and fishery safety devices (V-Pass terminals, distress beacons), serving government agencies and institutional customers through direct procurement.

Product overview

GMT provides an integrated maritime control and navigation ecosystem comprising four main solutions: 해상통합상황관제 (Integrated Maritime Situation Control), 해상교통관제 (Maritime Traffic Control), 해상풍력단지관제 (Offshore Wind Farm Control), and 스마트계류장관제 (Smart Berth Control). These are supported by named subsystems including K-MSIS (target fusion), K-VTOS (operations management), K-VTRS (voice/data playback), and K-VHF (communications). GMT also offers standalone product lines: navigational equipment (ECDIS, INS, e-Nav, V-Pass, 바다길잡이), communication equipment (AIS System, ISCS), and fishing safety equipment (Distress Beacon). The solutions layer real-time sensor data, AI-based video/audio analytics, and predictive monitoring into unified control platforms for maritime, aviation, and offshore energy environments.

Expansion highlights6 records

Emerging players

• Frequentis: Austrian company specializing in mission-critical control centers for air traffic management, maritime safety, and public safety. Overlaps with GMT's Smart Berth Control and integrated control room offerings and shares a similar government-customer base.
• SRT Marine Systems: UK-based provider of AIS-based maritime surveillance, vessel monitoring, and VTS solutions primarily for coast guards and fishery authorities — closely aligned with GMT's V-Pass fishery tracking and maritime monitoring product portfolio.

Direct peers

• Indra: Spanish IT and defense company with significant maritime traffic and coastal surveillance business, supplying VTS systems, port management platforms, and maritime domain awareness solutions to public-sector clients globally — comparable to GMT's integrated maritime situation control product.
• Furuno Electric: Japanese specialist in marine electronics (radar, ECDIS, AIS, navigation systems, fish-finding equipment), supplying both commercial and government customers. Overlaps directly with GMT's ECDIS, AIS, radar, and navigation safety equipment product lines.
• Japan Radio Co. (JRC): Japanese manufacturer of marine navigation and communication equipment (radar, ECDIS, GMDSS, AIS) for commercial vessels and government customers. Directly comparable to GMT's marine navigation, ECDIS, and communication system offerings.
• Kongsberg Gruppen: Norwegian technology conglomerate with a maritime surveillance division (Kongsberg Norcontrol) that builds Vessel Traffic Service systems, AIS networks, and integrated maritime domain awareness platforms sold to coast guards and port authorities worldwide — directly competing with GMT's core VTS and integrated maritime control offerings.
• Saab: Swedish defense and security company whose Saab TransponderTech and maritime security units provide VTS, coastal surveillance, and AIS products to coast guards and naval customers — overlapping with GMT's maritime traffic control and vessel monitoring offerings and already named as a GMT partner.

Broad incumbents

• Thales: French multinational with a large maritime surveillance portfolio (VTS, coastal radar, integrated maritime domain awareness) sold globally to navies, ports, and coast guards. Already named as a GMT technology partner, illustrating both overlap and the relationship dynamic.
• Wärtsilä Voyage: Finnish maritime technology company providing ship navigation, ECDIS, port and coastal solutions, and integrated bridge systems to commercial and government maritime customers. Comparable to GMT's navigation and vessel traffic management offerings, though at much larger scale.

Regional players
