The possibility of AGW period evaluation on the basis of single-point satellite measurements is analysed. Some amplitude and phase differences depending on wave spectral characteristics and environmental features are detected in variations of different atmospheric parameters which are caused by the AGW propagation. The comparison between the theoretical relationships linking different AGW parameters and their experimental behaviour enables us to estimate spectral characteristics of these waves, which is impossible from direct measurements. We present several methods for the estimation of the AGW period which are based on synchronous satellite measurements of different parameters. The periods of the waves observed from the DE2 satellite are calculated.
