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.

新型ku波段数字应答机的研究

本文旨在指出野生鸟类遥测技术中存在的一些问题，以及未来预防禽流感的技术期望。对于大中型候鸟，美国国家海洋和大气管理局气象卫星上的数据收集系统(ARGOS系统)已经能够绘制出它们的迁徙路线。但是，多普勒频移的推荐C/No为54dBHz，而计算出400bps数据上行所需的C/No为36dBHz。导航功能和数据通信之间的差距将接近18db。这只鸟必须为此付出代价。我们想提出下一代数字应答器，这是一种先进的DCS与多波束在ku波段进行机载处理(DCS和导航系统与多普勒频移)。在卫星天线为42dBi的情况下，地面终端的射频输出为13dBm，天线为2.25dBi，在BPSK下传输速率可达50bps。如果我们能在ku波段上安装新的数字应答器，这个带有鸟腿的终端将适合鸽子或海鸥的大小。
