@db2os do you happen to have more information about the modulation and the encoding?

Is it a transponder?

Hi Pierros,

It’s not a bent-pipe transponder, the bird transmitters are only activated through the transmitter on ISS and during certain periods… kind of CDMA… The station will also send its keplerian elements, so that the animal tracker only wake-up when in range of the ISS…
