13. Aircraft aerodynamics, structures and systems

A GNSS satellite transmission is

  • vertically polarised
  • horizontally polarised
  • right hand circular polarised

Explanation from PART66Online

GNSS satellites transmit using right-hand circular polarisation so that reception is largely independent of the receiver antenna's orientation and is less affected by ionospheric Faraday rotation than a fixed linear polarisation would be. This is why aircraft GNSS antennas are designed for right-hand circular polarisation.
