About company

G.L. Electronic

G.L. Electronic is a Czech independent company that has been offering the complete implementation of Hi-Rel electronic devices and wiring harnesses in the aerospace industry for over 11 years.

Since 2008, we have been realizing installation and assembly activities in cleanroom of ISO 8 and providing technical support in the production and integration of flight equipment in many different international space projects, both in the Czech Republic and abroad.

Cooperation with G.L. Electronic guarantees:

  • High level of quality
  • Small-series precision production
  • Flexibility to customer requirements, tailor-made solutions
  • Ability to react quickly to production changes or alternatives
  • The opportunity to come and see the course of production
  • Information protection, documentation guaranteeing customer data security
  • High level of certifications for production areas and operators

Our aims

Based on our experience and investments in the company, we are already able to implement the entire assembly process of flight devices and cable harnesses within the ECSS ESA standards in certified cleanroom. The main goal is to be a reliable partner for our customers in the implementation of scientific and commercial flight equipment. As experienced subcontractor, we strive for wider involvement between academic institutions and industrial companies using the support of the Czech Ministry of Transport in ESA programs.

We would like to be actively involved in projects such as Plato, Copernicus-Sentinel, Triton X, VEGA C / E, Ariane 6 etc.
