'Computed' (default) applies BNC's kinematic attitude model, including GPS noon/midnight turn manoeuvres, GLONASS yaw-fixed mode, and Galileo/BDS orbit-normal mode switching. 'Nominal' uses a simplified continuous Sun-pointing model without manoeuvre modelling. 'SSR' uses the yaw angle transmitted in the SSR phase bias message; select this option only if you trust the yaw values provided by the AC. If no yaw angle is available for a particular satellite in a given epoch, BNC falls back to 'Computed'. Note that the attitude model affects APC-referenced streams only; for CoM-referenced streams the AC has already applied attitude before encoding.</p><p>Note that the orbit information in the resulting combination stream is just copied from one of the incoming streams.
