Jotron Brand Guidelines: The 1967 Norwegian Maker of EPIRBs, AIS and ATC Radios

A 1967 start in television-antenna amplifiers.

Jotron was founded in 1967 as Jotron Elektronikk AS in Levanger, in Trøndelag in central Norway, according to the company’s history and Norwegian Wikipedia. The small firm started out making amplifiers for television antennas before widening its range. In 1978 it moved south to Tjølling, now part of Larvik in Vestfold; the company says the reasons were to be nearer its aviation and maritime customers and to join a larger electronics community. The company describes the business as built “stone by stone” over more than 55 years. Norwegian Wikipedia records that it stayed at Tjøllingvollen until March 2020, when it moved to new premises at Ringdalskogen in Larvik, an 11,000 square-metre headquarters by the company’s account.

Two product lines shaped the business early. In 1970 Jotron launched the Tron 1 emergency position-indicating radio beacon (EPIRB), developed on assignment for the Norwegian authorities; the company describes it as the first certified EPIRB anywhere and says it could be switched on by hand or automatically on contact with water. In 1975 it delivered its first 50-watt radio to Telecom Air Navigation, now Avinor, and so entered the air-traffic-control (ATC) market. In 1989, the company says, its Tron 30S 406 MHz EPIRB became the first EPIRB to be certified by COSPAS-SARSAT, the international satellite system for distress beacons.

From 1995 Jotron moved from selling single radios to supplying complete systems, including antennas, filters and remote-control equipment. MarineLink reported in September 2016 that Jotron had designed and produced ship internal communication and public-address and general-alarm systems since 1979, and that it had won two contracts to supply telephone and public-address systems for 18 new module-carrier vessels ordered through Vard Electro.

Beacons, AIS, radios and recorders.

Jotron’s 2026 catalogue groups its maritime communication products as AIS, EPIRBs, SARTs, VHF handheld radios, personal locator beacons and locators. Named ranges include the Tron AIS TR-8000 MkII Class A transponder, the Tron 60GPS and Tron 40 series of EPIRBs on float-free brackets, the Tron SART20 radar transponder and the Tron TR30 GMDSS handheld VHF radio, and a TronTracker locator is sold for keeping track of fishing gear. The company says these products are used on ships, vessels and energy installations around the world.

Its radio business builds VHF and UHF AM transceivers, receivers and transmitters for air-traffic control and for coastal and maritime communication, such as the TR-7750 family, together with remote-control consoles. In 2012 Jotron acquired Ricochet AS, adding recording equipment for the ATC market, the company says. In September 2012 SatNews reported that Jotron AS had launched the B85, an 85 cm stabilised maritime VSAT antenna designed for Ku-band with an upgrade path to Ka-band and remote access through the Jotron Remote Access Suite.

Manufacturing is split between Norway and Lithuania. Norwegian Wikipedia lists factories in Larvik and Kaunas. Jotron set up UAB Jotron in Kaunas in 2001 through a regional cooperation between Vestfold and the Kaunas region, and the company said in September 2026 that the plant had grown from seven employees to 120 and become its primary manufacturing centre, producing electronic modules and maritime and air-traffic communication products. The Kaunas building was officially opened in November 2001, and the company says products made in Lithuania received approvals from Japan Radio Company and the Japanese authorities in 2008.

Marine electronics and satcom.

Marine electronics and satellite-communications companies tend to present themselves through their equipment first. Their websites lead with product photographs of radars, chartplotters, sonar displays, antennas and satellite terminals, usually shown on a plain background or mounted on a mast, a wheelhouse roof or a radar arch. Domes and displays are shot from the same few angles so that a whole range reads as one family, and model names, sizes and frequency bands do much of the descriptive work.

Coverage is the second recurring image. Satellite-service providers and antenna makers publish coverage maps for each network or plan, from regional cellular zones to global satellite beams, and many now show several networks side by side as low-orbit services join older geostationary ones. Bridge and wheelhouse photography carries the human side: officers at consoles, screens glowing in a dark bridge, yachts at anchor, fishing boats and offshore vessels at work.

Airtime and connectivity plans are a large part of how these companies describe themselves. Data allowances, subscription terms, crew-internet packages and backup services are laid out in plan tables, named and grouped the way each company chooses, and a hardware maker may sell plans on its own network next to those of other operators. Network-management software, cyber security services and content for crews increasingly sit alongside the hardware.

Partner pages complete the picture. Dealer and installer networks, service points in ports, and the satellite operators and equipment makers a company works with are listed with their own names and marks. This guide describes each company’s identity from dated sources and the company’s own pages, and the colours and typefaces shown are unofficial interpretations rather than reproductions of any mark.

A Vestfold group adding navigation makers.

Jotron has grown abroad in steps. The company dates Jotron UK to 1980, part of the group since 1990, Jotron Asia in Singapore to 2002 and Jotron USA, in Houston, to 2003; it now lists offices in the UK, the Netherlands, the USA, Singapore and Lithuania, with its headquarters in Norway. In 2023 it acquired SKIPPER Electronics AS, adding about 30 employees and navigation products such as Doppler and electromagnetic speed logs and the ESN100 and ESN200 echo sounders, which are now sold under the SKIPPER name within Jotron. In 2025 it bought Micro Elektronische Producten B.V. of Amsterdam, a maker of voice communication systems, and on 19 December 2025 it announced the acquisition of AD Navigation AS, a Norwegian maker of portable pilot units used by maritime pilots.

Norwegian Wikipedia puts the workforce at about 370, some 200 of them at Jotron AS in Norway, and says about 80 percent of output is exported; the company itself says 90 percent of its products go abroad and that it controls the whole product chain, from development to support. Norwegian Wikipedia also notes that Jotron was named Vestfold company of the year, Årets Vestfoldbedrift, in 1991. On its website the company organises itself by markets, from ATC and coastal to maritime and energy, carries the line “Performance for Life” and names enthusiasm, precision and respect as its values; the Tron name runs across its beacons, transponders and radios. Its navigation catalogue lists a new SKIPPER SL1300 SATLOG speed log as in development, with SATLOG antennas offered alongside it.

For a design guide, Jotron shows how a mid-sized Norwegian manufacturer can hold one product family name across beacons, transponders and radios while adding acquired brands beside it. Compare McMurdo, another beacon maker, and Simrad, a fellow Norwegian marine-electronics name. For this guide we use a deep fjord blue, a beacon yellow and a cool coastal grey with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
