The method for assessment the volume of a forest stand based on measurements of the attenuation of navigation satellites signals in the L1 range and morphological features of forest species is presented. The dielectric model of a mixed dielectric with the natural structural features of the species of the forest stand was used. The option of restoring the biomass volume of the forest stand according to the radioscopy data on the mixed forest test site is considered. The practical applications of the method of continuous local monitoring of the forest stand condition in forest science are discussed.

The method for determining the stocks of stem wood using the measurement data of the linear attenuation coefficients of signals navigation satellites L1 range and general taxometric characteristics of the forest is presented. A variant of determining the stocks of stem wood by differences in contributions to the attenuation by layers of crowns and trunks is considered, taking into account the coordinate referencing of the trajectory of the probe signal in the tree stand.
