      The implementation of more advanced modulation formats such as Amplitude Phase Shift Keying (APSK), which can be spectrally more efficient and potentially less susceptible to adjacent channel interference than current aeronautical telemetry modulation schemes, could serve to mitigate telemetry frequency spectrum reductions and reallocations. This paper will detail initial laboratory transmitter measurements and observations of 16-APSK modulation performance in comparison to SOQPSK-TG.
