The Space System for Remote Sensing of the Earth Based on the <Emphasis Type="Italic">Arkon</Emphasis> Satellite (On the 20th Anniversary of the First Launch)

On the eve of the 20th anniversary of the first launch of the Arkon satellite, the article provides a retrospective of the birth, implementation, and development of this unique project that has no comparable counterparts. The authors also single out those remarkable teams of developers and their leaders whose activities have become part of the history of the Lavochkin Research and Production Association and its pride.     

“Bumerang” Must Return to Earth

Solar System Research - The “Bumerang” space mission to the satellites of Mars is discussed. The purpose of the mission is to study the satellites and return of soil samples from Phobos...     

Features of ballistic design of ARKON-1 remote-sensing space system for optoelectronic earth observations

SC orbit parameters are selected and substantiated based on the maximum efficiency criterion based on the requirements of comprehensiveness, periodicity, and the immediacy of data acquisition using the example of the ballistic design of the ARKON-1 space system for the optoelectronic observation of Earth developed by NPO Lavochkin.     

Methods of agrometeorological grain crop forecasts for the districts,farms, and fields

The methods are presented of agrometeorological forecasting of winter and spring grain crops for the district, all types of farm units, and field taking account of the regional crop forecast, weather conditions, cereal cropping technologies, and soil cultivation level. The additional yields of winter and spring wheat and spring barley and oat are developed depending on the soil cultivation level, summertime soil moistening, and doses of mineral fertilizers. The method tested on the basis of independent data demonstrated that the accuracy of such forecasts is 83–99% for the fields with intensive cultivation technology and 80% for the farm units.

On the problem of adequate agroclimatic support of the Russian economy under climate change conditions

Problems of adapting available methods, forms, and approaches to agroclimatic support of the economy under climate change conditions are under consideration. Development and operation of an automated reference-information system (ARIS) of agricultural resources, assessment of the environmental bioclimatic potential, and preparation of agroclimatic Atlases (with a reference to hazardous agroclimatic events) are dealt with. The process of adaptation includes development of such system of agroclimatic support of the economy, which would adequately reflect the actual state of agroclimatic resources, bioclimatic potential of the environment, hazardous agroclimatic events, etc., at any prescribed moment, at any point. The problem is supposed to be solved with a mechanism of agricultural monitoring as one of the methods of agroclimatic support of the economy.
