Technical Memorandum of National Aerospace Laboratory
In flight data analyses, information on the state of the atmosphere (temperature, pressure, and wind) along flight trajectory is necessary for the improvement of accuracy. Estimation of the state of the atmosphere based on NOAA polar orbit satellite remote sensing-data, which was used in HYFLEX (Hypersonic Flight Experiment) flight data analyses, are described. The accuracy of the present estimation is evaluated by comparing, with meteorological rocket observations. It is concluded that temperature and pressure can be estimated by the present method much better than by depending on the U.S. Standard Atmosphere model, and that the error can be much reduced at higher altitudes. However, the accuracy of the estimation of speed and direction of wind were not satisfactory, and are considered to be due to error in pressure estimation.
