Towards determining the parameters of layer with scattering irregularities that cause coherent echo, based on the Irkutsk Incoherent Scatter radar data
K. V. Grkovich, O. I. Berngardt
In the paper we have presented a technique of determining the scattering irregularities (that cause coherent echo) layer parameters using the Irkutsk IS radar data. It is shown tha…

On two approaches to the building of local models for electron density based on Irkutsk digizond data
O. I. Berngardt
In the paper the step-by-step principles for making local model of electron density are described. They are based on modulation principle - electron density dependence on time is a…

A case study of the mid-latitude GPS performance at nighttime during the magnetic storm of July 15, 2000
E. L. Afraimovich, O. I. Berngardt, O. S. Lesyuta +2
Using the geomagnetic storm of July 15, 2000 as an example, we investigated the dependence of GPS navigation system performance on the nightside at mid-latitudes on the level of ge…
