"Earth" satellite of the measurement error is less than 5 meters accuracy.

<P> Keywords: Aerospace </ P> <P> and the Geographical Survey Institute of Japan Aerospace Exploration Agency said recently that, through software upgrades and other methods, the Japanese "Earth" No Land Observing Satellite problem of insufficient accuracy of measurement is expected to .be resolved before in March. .</ P> <P> two agencies jointly issued the 16th, said a press release, "Earth" satellite at a height greater than the error information design goals, the main reason was not originally thought of satellite attitude control problem, .because a high degree of information to enhance the accuracy of the required data is still in the process of accumulation, and now these data have been gradually put in place. .In addition, by introducing a new software, satellites and three-dimensional measurement becomes easier, with the help of ground-based reference points, "the earth" was the height of the error is expected to meet the design standards of information, that error is less than 5 meters. .World Scientific reports http://tech. </ P> <P> In addition, software upgrades and technical personnel will also solve the problem of image distortion. .</ P> <P> Japan Aerospace Exploration Agency 8, said, "Earth" satellite of the measurement accuracy is insufficient to provide the necessary data to produce maps. .Satellite can distinguish objects as small as 1 meter ground </ P> </ p>.
