Abstract :
This paper intends to point out some problem of telemetry for wild birds and future technical expectations to prevent Avian Influenza. For medium to large migratory birds, the data collection system aboard the NOAA meteorological satellites (the ARGOS system) has been able to map their migratory routes. However, recommended C/No for Doppler shift ill be 54dBHz, while calculated required C/No for 400 bps data uplink is 36dBHz. The gap between navigation function and data communication will be almost 18 dB. The bird has to pay this overload. We would like to propose the next generation digital transponder that is an advanced DCS with multibeam on Ku-band to perform the onboard processing (DCS and navigation system with Doppler shift). In case of 42dBi antenna of the spacecraft, the ground terminal with 13dBm RF-output and 2.25dBi antenna can transmit upto 50 bps with BPSK. This terminal attached with a leg of a bird will be suitable for a dove or a gull in size, if we could put new digital transponder on Ku-band.
