MISMMS Exclusive-OR Height Rule

This MISB ST 0902 semantic rule checks the mutually exclusive height encoding rule for the sensor ellipsoid height fields.

The rule inspects each claimed MISMMS packet and rejects packets that contain both:

  • Tag 75: Sensor Ellipsoid Height (HAE)
  • Tag 104: Sensor Ellipsoid Height Extended (HAE)

The test passes when no claimed MISMMS packet carries both tags in the same packet.

The test fails when a packet reports Tag 75 and Tag 104 together.
