Introduction
China Aviation Magnetic Ltd. HH, commonly referred to as CAM HH, is a specialty manufacturer headquartered in Shanghai, China. The company focuses on the design, development, and production of magnetic navigation systems, magnetic control units, and related electronic components for the civil and defense aviation sectors. Established in the early 2000s, CAM HH has positioned itself as a key supplier of magnetic guidance solutions to both domestic airlines and international aerospace firms.
History and Background
Founding and Early Years
CAM HH was founded in 2002 by a consortium of engineers from the Shanghai Institute of Optics and Fine Mechanics and alumni of the Civil Aviation University of China. The original mission was to address the growing demand for reliable magnetic navigation aids in the rapidly expanding Chinese civil aviation market. Early operations were based in a modest facility in Pudong, with a team of twenty engineers and technicians. Within its first five years, the company secured contracts with several regional airlines for the installation of magnetic compass upgrades.
Growth and Expansion
By 2008, CAM HH had diversified its product portfolio to include magnetic heading indicators, attitude reference systems, and magnetic anomaly detection modules. The company opened a secondary manufacturing plant in Tianjin to cater to increasing domestic demand. In 2011, CAM HH became a listed entity on the Shanghai Stock Exchange under the ticker HH, providing the capital required for research and development and international market entry. The 2010s marked a period of strategic expansion, with partnerships formed with major aircraft manufacturers and the acquisition of a smaller magnetic sensor startup in Shenzhen.
Business Overview
Core Business Areas
The company's operations are segmented into three primary divisions: Magnetic Navigation Systems, Aviation Electronics, and Research & Development. The Magnetic Navigation Systems division supplies magnetic compasses, gyros, and hybrid attitude sensors for commercial aircraft, regional turboprops, and general aviation. The Aviation Electronics division focuses on avionics interfaces, display modules, and data link systems that integrate magnetic sensor outputs into cockpit displays. The Research & Development division, located at the Shanghai headquarters, conducts advanced research in magnetic materials, signal processing algorithms, and electromagnetic interference mitigation.
