The invention discloses a method for testing realtime service transmission performance of the WiMAX network, belongs to the wireless broadband access field. In the method, a mobile terminal establishes RTSP media session connection with a streaming media server; the streaming media server receives a session request according to the mobile terminal, determins corresponding coding speed, encapsulates realtime UDP messages, then sends to the mobile terminal through the WiMAX network, the mobile terminal analyzes received UDP messages; when the network connection is time-out, the mobile terminal stops the RTSP media session connection with the streaming media server, calculates performance indexes of the transmission rate, the packet loss rate, time delay and the time delay jitter according to the analysis result of the UDP messages. The invention also discoses a terminal for testing realtime service transmission performance of the WiMAX network. The invention acquires performance indexessuch as the transmission rate, the packet loss rate, time delay and the time delay jitter, etc., under different Qos allocation, improves testability and analyzability.

The invention provides a method for dividing multiple remote sensing parameter analyzing windows of a spacecraft. Through analyzing a multiple-remote-sensing-parameter association period and selecting a reference parameter acquisition dividing characteristic, accurate dividing for multiple parameter analyzing windows in a manner of alignment in a time scale is realized. According to the method of the invention, analyzing window dividing is performed through a remote sensing parameter reference dividing characteristic instead of a fixed or a slidable window, thereby preventing window drift caused by factors such as space environment and channel transmission, realizing accurate dividing of the remote sensing parameter analyzing windows and improving accuracy of subsequent characteristic extraction and diagnosis detection. According to the method of the invention, synchronous dividing is performed on a plurality of remote sensing parameters through the reference parameter; window alignment in the time scale is realized; analyzability of the remote sensing data is improved; and analyzing and digging of an association relation between multiple parameters are facilitated.

The invention discloses a network map rectifying and drawing method under dynamic map projection. The method comprises the steps of, first of all, according to the comparison of the projection types of clients sides and server sides, carrying out projection transformation calculation of geographical range values, then calculating reversely to acquire the rank numbers and the map levels of all the tiles to be loaded by using cutting principles of a tile map and requested parameters, and carrying out error correction to the geographical range values of each tile through the error deviation values of the tile map acquired by using a plurality of feature points. When each tile is downloaded, encryption is carried out by using a data encryption standard (DES) encryption algorithm, and the tiles are saved in an ini format file which has a same name with the map tiles in sequence. When the downloading of the needed map is completed, the ini file can be deciphered, the geographical range values and the like after correction are read, and the drawing of each map tile is achieved. The network map rectifying and drawing method under dynamic map projection achieves drawing of the network tiles after the error correction, greatly improves the accuracy of data, and enhances the analyzability of the data.
