there are several satellite base maps which can be applied to QGIS as the base map of the project and some of them are, Google Earth Base Map; Bing Virtual Earth Base Map; Esri Base Map; please follow the following steps, Go to Layers > Data Source Management; Go to the tab XYZ Connections; Add a New XYZ Connection
As a crucial component in GIS, a basemap contains reference information such as water features, roads, political boundaries, and topography, among others. It sets the initial geospatial context and provides navigational aids to the viewer, laying the foundation for data visualization.
Basemaps serve as a reference map on which you overlay data from layers and visualize geographic information. An individual basemap can be made of multiple feature, raster, or web layers. Basemaps are the foundation for your maps and provide context for your work. A sample basemap over Athens, Greece, is shown.
