一般的小型无人机体积小、速度低、带载荷能力有限，限制了机载动静压传感器的体积重量。小型硅压阻传感器具有小型化、数字化的优点，特别适合于对体积重量有要求的众多中小型无人机选用。本文结合某小型无人机全静压系统的研究，针对目前多运用于小型无人机上基于硅压阻传感器的全静压系统误差产生的原因进行了分析，并根据大多数无人机采用GPS导航的特点提出简便易行的校正方法。经过试飞验证，该校正法具有良好的性能和可靠性。
一般的小型無人機體積小、速度低、帶載荷能力有限，限製瞭機載動靜壓傳感器的體積重量。小型硅壓阻傳感器具有小型化、數字化的優點，特彆適閤于對體積重量有要求的衆多中小型無人機選用。本文結閤某小型無人機全靜壓繫統的研究，針對目前多運用于小型無人機上基于硅壓阻傳感器的全靜壓繫統誤差產生的原因進行瞭分析，併根據大多數無人機採用GPS導航的特點提齣簡便易行的校正方法。經過試飛驗證，該校正法具有良好的性能和可靠性。

The minitype unpiloted aircraft is of small size,low speed and has limit loading ability ,but the minitype silicon piezoresistance has the features of miniaturization and digitalization,especially suits medium and minitype unpliotd aircraft which has te requirements of size and weight.This paper analyzes the rason why the pitot-stadic pressure system based on silicon piezoresistance sensor nowdays has error on the minitype unpiloted aircraft by combining studying of certain minitype aircraft pitot-stadic pressure system,puts forward simple and convenient practical calibration method as per the characters of most of unpiloted aircrafts adopting GPS navigation.This calibration method has favorable performance and reliability after being verified by the flight test.
