04c — Simulators

Flight simulator and trainer servicing

Simulators and trainers combine theoretical training with operational practice — crew safety and training effectiveness depend on their reliability. We service both entire platforms and individual subsystems, including equipment no longer supported by the manufacturer.

Visualization systems

  • DLP/LCoS projectors and LED/laser light sources
  • Spherical screens and edge-blending systems
  • Geometric warping and GPU graphics servers

Cockpit and avionics

  • Control panels and analog/digital indicators
  • HOTAS systems and glass-cockpit modules
  • Cockpit lighting and symbology generation

Motion systems

  • Electric and hydraulic motion-platform actuators
  • Motion controllers and G-seat/G-belt systems
  • Encoders, torque and backlash calibration

Simulator IT infrastructure

  • Simulation servers and CPU/GPU clusters
  • PTP/NTP time-synchronization networks
  • Routers, switches, redundancy, and simulator UPS units

Audio and communications

  • Instructor intercoms and internal communication systems
  • 3D spatial audio generation
  • V/UHF radios and simulator radio bridges

Debriefing modules

  • Flight-data recorders and playback stations
  • After-action review (AAR) mission-analysis software
  • Instructor stations and assessment systems

Life-extension upgrades

We replace discontinued DLP projectors with LED/laser sources offering higher durability and lower operating costs. We retrofit pilot cockpit panels and integrate newer displays into legacy simulators — extending their service life by years.

Firmware and software backup

We perform comprehensive firmware backups for individual modules as well as full backups of simulator software. We create physical disk copies and secure configurations, enabling system restoration after a failure within hours rather than weeks.

8+ years of experience: we support Training Centers of the Polish Armed Forces and NATO simulators, maintaining training platforms from Airbus, Leonardo, Lockheed Martin, Embraer, Bell, and Boeing. Our procedures ensure ≥99.2% availability, and the average time to restore a critical visualization module does not exceed 6 hours — thanks to spare projectors and remote fault analysis.

04d — Security equipment

Security and screening equipment servicing

We service security equipment protecting borders, airports, and critical infrastructure against chemical, radiological, and terrorist threats. Our capabilities restore functionality to both the latest systems and equipment no longer supported by the manufacturer.

  • Mobile and stationary baggage X-ray scanners (RAPISCAN 600/900 series)
  • Handheld backscatter X-ray scanners
  • Walk-through metal detectors (WTMD) and personal screening systems
  • Vehicle and undercarriage scanning systems (UVSS)
  • EOD robots and ordnance disposal systems (TALON, PackBot)
  • Chemical and radiological detectors (AP2C/AP4C series)
  • Remote CBRN threat-analysis platforms
  • Discontinued equipment without OEM support

Accredited calibration

We calibrate detectors, scanners, and measuring equipment in cooperation with accredited bodies, in accordance with applicable standards and manufacturer documentation. After each calibration we issue a certificate of conformity along with the next inspection schedule.

Clearance verification and NDA handling

Servicing security equipment requires access-clearance verification before a request is accepted. Technical documentation is exchanged under a signed NDA, and the scope of work is agreed individually with the operating unit.

04e — Server rooms and IT

Server infrastructure and computer systems

IT reliability underpins the operational readiness of military units, training centers, and strategic institutions. We service the entire server-room environment — from disk arrays and servers to network infrastructure and integrated systems.

  • Disk arrays and backup systems — RAID rebuilds, mirroring configuration, data recovery
  • Physical servers — diagnostics of motherboards, controllers, power supplies and cooling systems
  • Networked computers — operator workstations, training terminals, control computers
  • Switches, routers, firewalls, and watchdogs
  • Integrated systems in simulators, command centers, and alarm systems
  • Backplanes, RAID controllers, and I/O modules

Preventive maintenance of IT infrastructure

Server cleaning, fan replacement, thermal pad replacement, and RTC battery replacement. After every repair we perform load testing of components and a compatibility audit of the replacement parts used.

IoT monitoring and lifecycle management

We deploy IoT sensors reporting temperature, vibration, and power parameters in real time. We continuously monitor component obsolescence and flag risks related to parts being withdrawn from the market.

05 — Techniques and packages

Component-level repair — BGA, μBGA, QFN

We perform complex component-level electronics repair, including devices in BGA, μBGA, and QFN packages. We use a full range of soldering techniques — from reflow and reballing to manual and microscope-assisted micro-soldering. This allows us to safely replace components and restore connections even on multilayer boards.

Reflow

Soldering SMD and BGA components under a controlled thermal profile

Reballing

Restoring solder balls under BGA/μBGA packages

Micro-soldering

Manual, microscope-assisted work on the smallest components

Multilayer boards

Safe restoration of traces and vias

Data security

Full control over information

All data media are encrypted, and access to test stations is controlled. Selected repairs are carried out on a closed network with no internet access, eliminating the risk of classified information leaks.

Quality standards

We work in compliance with these standards

  • IPC-7711/7721 Rework & Repair
  • MIL-STD-202 Test Methods
  • ESD ANSI/ESD S20.20
  • ISO 9001:2015 & AQAP 2110

FAQ

Frequently asked questions

Do you repair discontinued circuit boards?

Yes — we offer complex electronics repair and can upgrade equipment by replacing individual electronic components or sourcing functional replacements. This lets customers keep equipment operational that manufacturers want to replace with costly new systems.

How long does a standard repair take?

Typically 10 business days for most faults; complex cases up to 30 days.

Can I get a test report after the repair?

You will receive a service report listing the repair work performed. If needed, we can also provide a test protocol, a list of replaced parts, and microscope, X-ray, or thermal imaging photographs.

Do you service simulators that are no longer supported by the manufacturer?

Yes — we use reverse engineering to design functional replacements for discontinued components. This applies to DLP projectors, cockpit panels, and older-generation electronic modules alike. This allows training centers to keep simulators in service even after official OEM support ends.

Is calibration of security equipment carried out by accredited bodies?

Yes — we calibrate CBRN detectors, X-ray scanners, and detection gates in cooperation with accredited laboratories, in accordance with applicable standards and manufacturer documentation. After each calibration we issue a certificate of conformity along with the next inspection date.

Can you remotely monitor server temperature and vibration?

Yes — we deploy IoT sensors reporting temperature, vibration, and power parameters in real time. Data is sent to an alarm dashboard, and deviation alerts let you react before a minor anomaly turns into a critical IT failure.
