Why Choose Stratux?

Cost

At $200-450 (depending on build), Stratux is significantly cheaper than commercial alternatives while providing the same core functionality.

Open Source

  • Full source code available
  • Community-driven development
  • No subscription fees ever
  • Modify and customize freely

Repairability

  • Replace individual components (SDR, GPS, Pi)
  • No “black box” — you can fix it yourself
  • Parts available on Amazon

Learning

Building Stratux teaches you how ADS-B actually works. Many pilots find this valuable for understanding their avionics ecosystem.

Why Choose Commercial?

Convenience

  • Single integrated unit
  • Built-in battery
  • No assembly required
  • Polished industrial design

Support

  • Warranty
  • Customer service
  • Guaranteed compatibility

Certification

Some commercial products are TSO certified for certain uses (though none replace certified avionics for IFR).

What Stratux Does Just As Well

  • ADS-B reception quality — Same SDR technology as commercial units
  • Weather data — Identical FIS-B feed from FAA
  • EFB compatibility — Works with ForeFlight, Avare, FlyQ, Garmin Pilot, and more
  • AHRS quality — Same MEMS sensors used in commercial products

What Stratux Doesn’t Have

  • CO detection — Sentry’s main differentiator
  • Built-in battery — You add an external power bank
  • Sleek enclosure — Functional but not as polished
  • Warranty — Community support only

Real-World Performance

In side-by-side tests, Stratux performs comparably to commercial receivers for traffic and weather reception. The core technology (RTL-SDR radios, u-blox GPS) is similar or identical.

Where commercial products may edge ahead: - Slightly better antenna integration - Optimized power management - Faster startup time

Who Should Build Stratux?

✅ Good fit: - Budget-conscious pilots - Tinkerers who enjoy DIY - Those who want to understand the technology - Backup receiver for primary commercial unit - Flight schools needing multiple units

❌ Maybe not: - Want plug-and-play with zero hassle - Need CO monitoring - Prefer commercial warranty/support - Don’t want to troubleshoot occasional issues

Hybrid Approach

Many pilots use Stratux as a backup or secondary receiver. Some run both a commercial unit and Stratux for redundancy.

Stratux gives you 90% of the capability at 30% of the price. The tradeoff is some DIY effort and self-support.
