Key Takeaways:

  • The article details the replacement of an airplane's obsolete Narco 50A transponder and encoder with a new Stratus ESG transponder and a high-accuracy encoder.
  • A significant part of the upgrade involved the meticulous installation of a new external GPS antenna on the fuselage, requiring drilling, strengthening, sealing, and precise placement to avoid signal shadowing.
  • This upgrade integrated the Stratus 2S unit, allowing it to receive enhanced satellite information from the newly installed GPS antenna, thereby improving the aircraft's ADS-B capabilities.

Stratus ESG transponder and Stratus 2S

My new Stratus ESG Transponder and my Stratus 2S. The 2S is connected by an antenna and power cable inside an open bay in my panel. The Stratus 2S obtains satellite information from the newly installed GPS antenna, so it no longer has to have a visible view of the sky. However, it must retain the proper fore and aft orientation in order to provide the necessary attitude information.
