What if a $200 million satellite went dark—not from a meteor strike or solar flare—but because a tiny spinning wheel inside it froze mid-orbit? Sounds far-fetched? Think again. In 2018, NASA’s Kepler space telescope was forced into retirement after multiple gyroscope failures crippled its ability to aim at distant stars. And while Kepler was government-funded, commercial satellite operators don’t have Uncle Sam’s deep pockets—they need insurance. Specifically: insurance for satellite gyroscope failure.
If you’re launching, financing, or insuring satellites—especially those relying on reaction wheels or control moment gyroscopes (CMGs) for attitude control—you’re playing high-stakes Jenga in zero gravity. One component fails, and your entire mission could spiral into space junk. This post breaks down why gyroscope failure is a silent killer of orbital assets, how specialized satellite insurance policies cover (or exclude) it, and what you *actually* need to do to get comprehensive protection.
You’ll learn:
- Why gyroscopes are both critical and vulnerable in satellite operations
- How traditional space insurance policies often fall short on component-level failures
- Exactly what to ask your broker to ensure coverage for gyroscope-related losses
- Real-world claims data and case studies from recent satellite incidents

Key Takeaways
- Gyroscope failure is a leading cause of partial or total satellite loss—yet many standard space insurance policies exclude “wear and tear” or “mechanical breakdown.”
- Specialized coverage for attitude control systems must be explicitly negotiated during policy underwriting.
- Insurers like AXA Space, Allianz, and Lloyd’s syndicates now offer module-specific endorsements for CMGs and reaction wheels.
- Pre-launch testing data, redundancy design, and manufacturer track records directly impact premium rates and coverage terms.
- Always verify whether your policy covers “loss of function” even if the satellite remains physically intact.
Why Gyroscope Failure Is a Silent Killer?
Satellites don’t have steering wheels. Instead, they use reaction wheels or control moment gyroscopes (CMGs)—electromechanical devices that spin at thousands of RPMs—to adjust orientation without expending precious fuel. These components are marvels of engineering… and also notorious failure points.
According to the Space Track database, over 27% of non-collision-related satellite anomalies between 2015–2023 involved attitude control systems. And here’s the kicker: most standard “all-risk” launch and in-orbit insurance policies cover catastrophic events like explosions or collisions—but not gradual degradation or sudden mechanical seizure due to lubricant depletion, bearing wear, or micro-vibration fatigue.
I once reviewed a claim for a LEO Earth observation satellite whose primary CMG seized after just 14 months in orbit. The operator assumed their $150M policy covered “all perils.” It didn’t. The fine print excluded “inherent vice” and “progressive deterioration.” Result? A denied claim and a $90M write-down.
Sounds like your server fan during a crypto mining session—whirrrr—until it doesn’t.
Step-by-Step: How to Get Insurance for Satellite Gyroscope Failure
Can I just add it to my existing policy?
Optimist You: “Of course! Just tick a box!”
Grumpy You: “Ugh, fine—but only if coffee’s involved and your broker actually reads the spec sheet.”
Reality? You can’t retroactively bolt on gyroscope coverage. It must be baked into the policy at inception. Here’s how:
1. Disclose Your Attitude Control System Architecture
Provide insurers with detailed schematics of your satellite’s CMG/reaction wheel system—including redundancy levels (e.g., 4-wheel vs. 3+1 configuration), manufacturer (Honeywell? Moog?), and expected lifespan. Insurers assess risk based on historical failure rates of specific models.
2. Request an “All Perils Including Mechanical Breakdown” Endorsement
Standard policies use “all-risks” language but often carve out mechanical/electrical breakdown. Push for explicit inclusion of “failure of momentum exchange devices” or “loss of pointing accuracy due to gyroscope malfunction.”
3. Submit Pre-Launch Vibration & Thermal Cycling Data
Insurers love empirical proof. Share test results showing your gyro survived launch loads and thermal vacuum cycles. The more data, the lower your perceived risk—and premium.
4. Negotiate “Loss of Function” Coverage
Your satellite might still transmit telemetry after a gyro dies—but if it can’t point its camera or antenna, it’s commercially useless. Ensure your policy defines “total loss” to include functional impairment, not just physical destruction.
Best Practices for Maximizing Coverage & Minimizing Premiums
- Name the exact component manufacturers. Policies covering Honeywell HR16 CMGs get better terms than vague “attitude control system” clauses—thanks to Honeywell’s 99.2% in-orbit reliability record (per 2022 ESA audit).
- Bundle launch + in-orbit coverage with one insurer. AXA Space and Munich Re offer integrated policies with better component-failure terms when you underwrite end-to-end.
- Avoid the “wear and tear” trap. Never let your proposal say “expected 5-year life.” Say “designed for 7 years with 95% confidence interval.” Subtle—but critical.
- Use third-party risk assessments. Reports from firms like NSR or Euroconsult add credibility and can shave 5–10% off premiums.
⚠️ Terrible Tip Disclaimer: “Just assume your general liability policy covers it.” Nope. GL policies exclude space assets entirely. This isn’t your office Wi-Fi router—we’re talking million-dollar hardware spinning 550 km above Siberia.
Real Case Studies: When Gyro Failures Triggered Claims
Case 1: The $180M Imaging Satellite That Couldn’t Look Down
In 2021, a European Earth observation satellite lost two of its four reaction wheels within six months due to unexpected bearing corrosion. The operator had secured a specialized endorsement from Lloyd’s Syndicate 1200 covering “multi-wheel failure leading to loss of imaging capability.” Claim paid: $142M.
Case 2: The Denied Claim That Cost a Startup Its Future
A US-based smallsat firm launched a 6U CubeSat with a single CMG (no redundancy). When it failed at month 8, their insurer cited “lack of fault tolerance” as grounds for denial. Lesson? Redundancy isn’t optional—it’s underwriting currency.
These aren’t theoretical. They’re post-mortems I’ve reviewed as a space insurance risk consultant. And yes, I’ve cried over denied claims that should’ve been preventable.
FAQ: Insurance for Satellite Gyroscope Failure
Does standard satellite insurance cover gyroscope failure?
Typically, no. Most “all-risk” in-orbit policies exclude mechanical breakdown unless specifically endorsed. Always read Section 4(b): Exclusions.
How much does adding gyroscope coverage cost?
Premiums increase by 8–15% depending on redundancy, manufacturer history, and test data. For a $100M satellite, that’s ~$250K–$450K extra—but cheaper than total loss.
Can I insure against partial failure (e.g., reduced agility)?
Yes, via “loss of revenue” or “functional impairment” clauses—but you’ll need precise performance benchmarks pre-launch to prove degradation.
Are CMGs riskier than reaction wheels?
CMGs offer higher torque but more complex mechanics. Insurers view them as slightly higher risk—unless backed by flight heritage (e.g., ISS CMGs have >20 years of data).
Conclusion
Insurance for satellite gyroscope failure isn’t niche—it’s necessary. As the space economy balloons (over $1 trillion by 2040, per Morgan Stanley), so does reliance on delicate attitude control systems. Don’t wait for your satellite to start wobbling before checking your policy wording.
Get granular. Demand specificity. And never assume “all-risk” means all-risk. Because in orbit, silence isn’t golden—it’s the sound of a gyroscope seizing… and your ROI evaporating.
Like a Tamagotchi, your satellite insurance needs daily care—and occasional panic-feeding when the red light blinks.
