Helzel Messtechnik GmbH

What Helzel Messtechnik GmbH does

Helzel Messtechnik GmbH is a privately-held German engineering firm founded in 1995 in Kaltenkirchen, Schleswig-Holstein, specializing in shore-based High Frequency (HF) radar systems for ocean remote sensing and coastal surveillance. The company designs and manufactures two core product lines: the WERA (WEllen RAdar) system for oceanographic measurement of surface currents, wave parameters, and wind direction, and the OTHR (Over-The-Horizon Radar) system for ship detection and tracking across exclusive economic zones at ranges up to 200 nautical miles. Both platforms are built on a proprietary FMCW (Frequency Modulated Continuous Wave) transmission architecture originating from research at the University of Hamburg, which Helzel industrialized starting in 2000. The portfolio also includes add-on modules such as the WERA-HAZ-MAN crisis management system and a Dual Frequency WERA configuration for optimized range and resolution trade-offs.

The company's technology is distinguished by very low RF transmission power, spatial separation of receive and transmit antennas for noise decoupling, and a dual-frequency capability that allows a single receive array to operate across two adjacent bands. Helzel's signal processing software is delivered as executable modules with lifetime licenses and an update service, and basic ideas are openly published within the WERA user community to prevent third-party patenting. The company holds ISO 9001:2015 certification, a Radio Equipment Directive (RED) certificate for EU market compliance, and an FCC certification for US operation under FCC ID 2AV3S. Over 150 WERA and OTHR systems have been installed in more than 25 countries worldwide.

Helzel operates a hybrid go-to-market model combining direct enterprise sales — using an inquiry form and proposal checklist process — with a global channel partner network spanning Australia, Argentina, Brazil, Canada, Cyprus, Ecuador, France, and Greece. Customer segments include oceanographic research institutes, meteorological offices, naval and homeland security agencies, port authorities, search and rescue organizations, disaster management agencies, offshore wind and oil & gas operators, and system integrators. Revenue derives from one-time hardware sales, professional services and training, and recurring lifetime software update services. The company maintains a small team of approximately 8 employees embedded in the Maritime Cluster Norddeutschland / Schleswig-Holstein SME network.

Core offering

Helzel Messtechnik GmbH designs, manufactures, and sells shore-based High Frequency (HF) radar systems for ocean remote sensing and coastal surveillance. The core products are the WERA ocean radar (measuring surface currents, waves, and wind direction) and the OTHR over-the-horizon radar (for ship detection and tracking up to 200 nautical miles). The company also provides configuration services, user training, and lifetime software licenses with updates.

Product overview

Helzel Messtechnik GmbH offers a portfolio of HF radar systems centered on two main products: the WERA ocean radar system for oceanographic measurements (surface currents, waves, wind direction) and the OTHR (Over-The-Horizon Radar) system for ship tracking and coastal surveillance. The WERA system is the primary platform, with the OTHR derived from WERA technology for defense and security applications. Optional modules include the WERA-HAZ-MAN for crisis management and the Dual Frequency configuration for enhanced measurement flexibility. All systems are shore-based, utilize FMCW transmission technology, and provide real-time quality-checked data. Over 150 systems have been installed worldwide in more than 25 countries.

Regional players

• IACIT: IACIT is Helzel's Brazilian partner and also a developer of HF radar and ocean surveillance technology in South America. Comparable as a regional player focused on HF ocean radar and naval surveillance in the Latin American market.
• ASL Environmental Sciences: ASL is both a Helzel channel partner in Canada and an integrator/distributor of competing oceanographic measurement instruments. Comparable as a regional player that pairs HF radar deployments with complementary ocean sensors in the North American market.
• Actimar: Actimar is a French marine engineering and consulting firm that serves as Helzel's channel partner in France. Comparable as a regional provider of oceanographic measurement and offshore engineering services, with overlap in met-ocean and offshore wind applications.

Broad incumbents

• L3Harris Technologies: L3Harris supplies HF surface wave radar systems (e.g., the STRADIS line) for ocean current mapping and ship detection. It is one of the closest large-scale competitors to Helzel in the HF ocean radar niche.
• Thales Group: Thales is a major naval radar and maritime surveillance provider (e.g., Coast Watcher, SMART-S). Comparable on the coastal surveillance / EEZ protection use case where Helzel's OTHR competes, but Thales serves a far broader defense electronics portfolio.
• Lockheed Martin (Naval Radar): Lockheed Martin supplies integrated naval and coastal defense radar systems globally. As a defense prime, it competes in ship-detection and coastal surveillance procurements that overlap with Helzel's OTHR offerings.
• Saab (Coastal Surveillance): Saab offers broader maritime surveillance solutions including coastal radar and command-and-control systems used for EEZ protection. Comparable on the OTHR ship-tracking application, though Saab's portfolio is much wider and not specialized in HF ocean radar.
• Indra Sistemas: Indra provides coastal surveillance and maritime domain awareness solutions for navies and port authorities. Comparable on the OTHR coastal surveillance use case, particularly in Europe and Latin America where Helzel also has partners.

Others

• Rohde & Schwarz: Rohde & Schwarz is a leading HF transmitter and radio equipment supplier. Comparable as a technology ecosystem participant: Helzel's FMCW transmission architecture relies on high-quality HF radio subsystems where Rohde & Schwarz is a benchmark supplier and adjacent competitor in defense/naval communications.

Direct peers

• CODAR Ocean Sensors: CODAR Ocean Sensors is the most direct peer — a US-based pioneer in HF radar for ocean current and wave monitoring. Its SeaSonde system competes head-to-head with Helzel's WERA for oceanographic research and coastal monitoring deployments worldwide.
