G.L. Electronic (SME), an independent Czech company, has been providing complete implementation of Hi-Rel electronic devices and assembly of cable harnesses in the aerospace industrial sector since 2008. The company also offers testing services in ISO8 certified clean rooms and in a testing laboratory accredited according to the international standard ČSN EN ISO/IEC 17025:2018.

Competences and capabilities

The production of electronic devices takes place within the framework of ESA standards and ECSS standards in ISO8 certified clean rooms. The production is carried out by technicians certified according to ESA standards.

G.L. Electronic is specialized in two manufacturing segments:

Aerospace segment – production of Hi-Rel electronics for aerospace devices and instruments.

Ground segment & EGSE – complete electrical assembly, mechanical integration and testing of rack boxes for harnesses TVAC with testing instruments.



  • assembly, repair and modification of PCBs (level EM, EQM, FM)
  • assembly of cable harnesses


  • quality control according to ECSS specifications
  • technical and consulting support in the field of design
  • bonding and conformal coating
  • final routing and integration of harnesses
  • testing: climate and vacuum chamber, electrical testing of harnesses (continuity and insulation test and double-wire measuring for 258 points), wire tension test, microsection of crimped joints, endoscopic visual inspection
