Embodiment Construction
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] A pseudolite site simulation layout method based on DEM data processing, comprising the following steps:
[0028] (1) Input the original DEM data of the site and the coordinate information of the DEM data, and use the coordinate information of the DEM data to convert the original DEM data into plane coordinate data through Gaussian projection;
[0029] (2) Generate image data with elevation color according to the original DEM data and the coordinate information of the DEM data;
[0030] (3) Display the site image according to the image data, wait for the user to lay out pseudolites in the site image and configure the antenna parameters and transmit power of each pseudolite. The actual position coordinates of the satellites in the site; when deploying pseudolites, you can directly operate on the site image by clicking with the mouse, or yo...
