earth satellite造句
例句与造句
- The remote sensing refers to air to ground one , namely from different working platform far away the ground ( for example gao ta , balloon , airplane , rocket , the artificial earth satellite , spaceship , aerospace craft and so on ) , through the sensor , exploring the information ( radiation ) to the earth ' s surface electromagnetic wave , and after the information transmission , processes , estimation and analysis , it can be regarded as a kind of comprehensive technology of surveying and monitoring earth ' s resources and its environment
摘要遥感是指空对地的遥感，即从远离地面的不同工作平台上（如高塔、气球、飞机、火箭、人造地球卫星、宇宙飞船、航天飞机等）通过传感器，对地球表面的电磁波（辐射）信息进行探测，并经信息的传输、处理和判读分析，对地球的资源与环境进行探测和监测的综合性技术。 - Under the circumstances of all - round blockade and embargo imposed by the united states and other western countries , china successfully developed intermediate and short - range missiles in 1964 , and succeeded in launching its first man - made earth satellite in 1970 , and a recoverable satellite in 1975
在美国等西方国家对中国实行全面封锁和禁运的情况下， 1964年中国就已经研制成功了中近程导弹， 1970年中国成功地发射了第一颗人造地球卫星， 1975年，中国又成功地发射了返回式卫星。 - Second part - the main contribution and research results of this paper are focused on as follows : ( 1 ) how to use the measurements of a dual frequency gps receiver to determine the ionospheric delay correction model for single frequency gps of a local range ; ( 2 ) how to separate the instrumental biases with the ionospheric delays in gps observation ; ( 3 ) how to establish a large range grid ionosphere model and use the gps data of chinese crust movement observation network to investigate the change law of ionospheric tec of china area ; ( 4 ) how to improve the effectiveness of correcting ionospheric delays for waas ' s users under adverse conditions . ( 5 ) how to establish the basic theory and the corresponding framework of monitoring the stochastic ionospheric disturbance using gps ( 6 ) how to improve the modelling ability of ionospheric delay according to its diurnal , seasonal , annual variations based on gps ; ( 7 ) how to meet the demand of correcting the ionospheric delay of high - precision orbit determination for low - earth satellite using a single frequency gps receiver 1 extracting ( local ) ionospheric information from gps data with high - precision the factors are systematically described and analyzed which limit the precision of using gps data to extract ionospheric delays
