BNC considers the first AC in the 'Combination Table' as the 'Master AC'. The orbit information in the final combination stream is then just copied from the 'Master AC's orbits. Moreover, the update rate of the combination product is defined by the update rate of the 'Master AC's stream. If incoming streams have different rates, only epochs that correspond to the 'Master AC's update rate are used. Skipped epochs show however up in plain ASCII format ed files described below. This means that the 'Master AC' is responsible for two things: the satellite positions and the combination rate.1404 Note further that the sequence of entries in the 'Combination Table' is of importance.

You should therefore specify the 'ANTEX File' path under tab 'PPP (2)' if you want to save a combination product in SP3 format. If you don't specify an 'ANTEX File' path there, the SP3 file contents will be refered to the satellites APCs.1447 As an SP3 file contents should be referred to the satellite's Center of Mass (CoM) while correctors are referred to the satellite's Antenna Phase Center (APC), an offset has to be applied as which is available from an IGS ANTEX file (see section 'ANTEX File').
