According to the principle of air pressure altitude measurement, the paper introduces the composition and the working principle of digital measuring system, and it discusses the circuit design of every part of the measuring system and flow chart of program design .
从无人机气压高度测量的原理出发,介绍了数字式气压高度测量系统的组成和工作原理,并详细论述了测量系统各组成部分的电路设计以及程序设计流程图,最后通过测试验证了以FPGA芯片为核心的无人机气压高度测量系统的可行性,分析了系统的误差来源。
4)  barometric height
气压高度
1.
The method to measure the barometric height for UAV(Unmanned Aerial Vehicle) is proposed,in which the barometric height is calibrated by GPS(Global Position System) height and is compensated by atmosphere temperature.
针对某型民用摄像无人机的高度测量问题,提出了利用GPS校准、带温度补偿的气压高度测量方法。
5)  Pressure Altitude
气压高度
1.
After a series of theoretical analysis and statistic reckoning,the results show that the geometric altitude may be several hundreds of feet and even much lower than the pressure altitude because the actual air temperature is well below the standard air temperature in winter.
对飞机在冷天气起飞时是否应该对高度进行修正问题进行了研究,通过理论分析和实际计算证明:由于冬季低温天气实际温度大大低于标准大气温度,几何高度可能比气压高度低几百英尺甚至更多。
6)  barometer [英][bə'rɔmɪtə(r)]  [美][bə'rɑmətɚ]
气压高度表
1.

2.
In order to overcome those limitations, and on the premise that the receiver can measure the pseudo-range between the user and satellite and with the help of barometer, this paper put forward the pseudo-range integration model of RDSS and the strap-down inertial navigation system with high precision clock, rubidium clock being the internal clock of the RDSS receiver.
基于北斗双星定位系统(RDSS)采用有源定位体制存在一定的局限性,在接收机能够测量用户至卫星的伪距信号以及在气压高度表辅助的前提下,提出了利用铷钟作为接收机内部时钟的RDSS与捷联惯导进行伪距组合的模型,建立其卡尔曼滤波的状态方程与量测方程。
3.
If the receiver could measure the pseudo-ranges from the user to the satellites,with the help of barometer,the RDSS could be integrated with the strap-down inertial navigation system based on pseudo-range.
介绍了双星定位系统(RDSS)的局限性,提出了利用高精度时钟,即铷钟作为接收机内部时钟,如接收机能够测量用户至卫星的伪距,在气压高度表的辅助下,双星定位系统可以与捷联惯导进行有效的伪距组合。
补充资料:大气压
又称“大气压强”,简称“气压”。与大气接触的面上所受到的气体分子的压强。单位用百帕表示。随高度升高而降低,如高山顶上的大气压比山脚下要低。在同一高度的大气压,气温低,密度大,大气压就高;反之,大气压就低。
