CONTRAVES Product Lines We Repair
Our engineers are trained on the full CONTRAVES product range. Below are the major product families we service.
Contraves Electro-Optical Tracking Systems
Precision optical tracking and fire control systems using gimbal-mounted cameras, infrared sensors, and laser rangefinders. Common faults include gimbal servo instability, optical alignment drift, and sensor calibration errors requiring specialist realignment equipment.
Contraves Radar Control Units
Radar signal processing and antenna control electronics for air defence and marine surveillance applications. Repairs address RF amplifier failures, transmit/receive module degradation, and antenna drive servo malfunctions common in saltwater or high-vibration environments.
Contraves Servo Drive Assemblies
High-precision AC and DC servo motor drives used in gimbal actuation, antenna positioning, and weapon system stabilization. Typical failures include power thyristor breakdown, servo loop instability, and position feedback encoder faults requiring dynamic calibration.
Contraves PLC and Automation Modules
Programmable logic controllers and I/O modules for integrated fire control and surveillance automation. Common issues involve memory corruption, communication protocol failures, and sensor interface card degradation in harsh operational environments.
Contraves Power Supply Systems
Regulated DC and AC power modules designed for 24/7 continuous operation in defence systems. Failures include capacitor degradation (especially in high-temperature installations), voltage regulator burnout, and battery charging circuit faults.

Common CONTRAVES Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTRAVES equipment arriving at our workshop.
- ✓Gimbal servo oscillation and tracking jitter — Contraves gimbal systems lose stability due to degraded servo amplifier gain settings, mechanical bearing wear, or encoder feedback signal noise. Saltwater corrosion and vibration in coastal/naval installations accelerate servo loop instability and position lag.
- ✓Optical alignment loss and image blur — Contraves electro-optical systems drift out of collimation due to thermal expansion, mechanical shock, or mirror coating degradation. Laser rangefinder misalignment prevents accurate target distance measurement, critical for fire control accuracy.
- ✓Radar transmitter power loss and reduced range — Contraves radar RF amplifiers fail due to power transistor/thyristor junction burnout, often triggered by VSWR mismatch when antenna feedlines corrode. Magnetron aging and klystron filament degradation also reduce transmit power over time.
- ✓Fire control computer reboot loops and fault code 0x07 — Contraves fire control computers enter boot loops due to corrupted EPROM/Flash memory, failing CMOS battery, or power supply brownout. Extended operational stress in high-vibration environments causes solder joint fractures on CPU module connectors.
- ✓Servo position feedback loss (encoder fault) — Contraves gimbal encoders fail due to brush wear, contamination in optical encoder windows, or connector corrosion in sea spray environments. Hall-effect position sensors degrade when exposed to electromagnetic interference from radar transmitters or high-power switching circuits.
- ✓Power supply voltage instability and ripple noise — Contraves 28V DC supplies develop excessive ripple due to failing filter capacitors (electrolytic degradation in high-temperature installations) or voltage regulator IC failure. Aged power modules cannot maintain regulation under peak load transients from servo motor acceleration.

Frequently Asked Questions — CONTRAVES Repairs
Do you repair Contraves equipment anywhere in India?+
Yes. Synchronics repairs the full Contraves product range — fire control systems, electro-optical trackers, radar modules, servo drives, and automation controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All repairs are performed at our certified facility in Vadodara, Gujarat, with same-day diagnostics and typical turnaround of 7-14 days depending on complexity.
Does Synchronics work on legacy Contraves fire control systems from 1980s-1990s?+
Yes. Contraves fire control systems are mission-critical for Indian defence platforms — we specialize in legacy Skyguard, Gepard, and IRST installations that remain operational across the Indian Navy and Army Air Defence Corps. We maintain component datasheets, spare parts catalogues, and firmware archives for systems reaching 30+ years old. Our engineers understand obsolescence challenges and source equivalent military-grade replacements for end-of-life components.
What certifications and documentation do Synchronics provide for Contraves repairs?+
We provide Contraves-standard repair documentation including component traceability, test records, calibration certificates, and functional test reports. All military-grade repairs are logged with part serial numbers, repair dates, and engineer sign-off. We supply complete technical handover documentation required by defence establishment asset management systems. Repairs meet Contraves original specifications verified against technical manuals and engineering drawings.
What is the typical cost of Contraves servo amplifier repair versus replacement?+
Contraves servo amplifiers (CPA Type and gimbal drive controllers) typically cost INR 3-8 lakh new. Synchronics repair costs range INR 1.2-2.5 lakh depending on failure mode — power device replacement, capacitor refurbishment, or full servo tuning. Most failures are economically repairable; replacement is only necessary for severe mechanical damage or obsolete models. We provide upfront cost estimates after initial diagnostics.
Can Synchronics recalibrate Contraves optical tracking systems to original accuracy specifications?+
Yes. Synchronics uses collimation benches, laser autocollimators, and Contraves-equivalent test fixtures to realign electro-optical systems to sub-arcsecond precision. We perform boresight correction, gimbal mechanical alignment, and rangefinder calibration using calibrated reference targets. Post-repair verification confirms line-of-sight accuracy meets Contraves engineering specifications required for fire control operations.
How do I send my CONTRAVES unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a CONTRAVES drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on CONTRAVES repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your CONTRAVES unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
