To georeference an AutoCAD file with the help of a Google Satellite map in QGIS

you can follow the steps below:

Open QGIS and load the AutoCAD file you want to georeference. Load the Google Satellite map by going to the "XYZ Tiles" section under the "Browser" panel on the left-hand side of the QGIS interface. Right-click and select "New Connection" and enter the following details: Name: Google Satellite URL: https://mt1.google.com/vt/lyrs=s&x={x}&y={y}&z={z} Once the Google Satellite map is loaded, make sure it is visible in the main window by clicking on the "Google Satellite" layer in the "Layers" panel. Click on the "Georeferencer" tool in the "Raster" menu and the "Georeferencer" window will open. In the "Georeferencer" window, go to "File" and select "Load raster." Browse to the location of the AutoCAD file and select it. Select the "Transformation type" that you want to use. If you're unsure, select "Thin Plate Spline." Use the "Add Point" button to add control points to the AutoCAD file. Click on a known point on the AutoCAD file, then click on the corresponding location on the Google Satellite map. Repeat this process for at least four control points, preferably more. Once you have added control points, click on the "Transformation" menu and select "Transform." The georeferenced AutoCAD file will be created and added as a layer to the main QGIS window. Note: Make sure that the projection of the AutoCAD file and the Google Satellite map are the same before starting the georeferencing process. If they are not, you will need to transform one of the layers to match the other.
