Abstract

The paper presents the results of designing the small satellite created in the JSC «Academician M.F. Reshetnev «Information Satellite Systems» for Earth observation purposes.

The objective of this scientific work is creation of the Earth remote sensing small satellite, which will fully comply with the world trends of space technology progress and the current SC technical requirements.

This objective is achieved due to creation of the Earth remote sensing small satellite based on the new multipurpose space platform — «NT-100-01». This platform uses the active, triaxial attitude determination and control subsystem, the main loop of which is designed on the basis of star trackers and control drive wheels. Such an engineering solution allows to use the satellites on the «NT-100-01» platform basis to perform tasks of high-accuracy shooting of the Earth surface in different optical and radio ranges, as well as to perform, if necessary, the satellite repointing for shooting of objects that are not covered by the satellite-covered area.

The small satellite could be launched into low circular operational orbit by single launch (including concurrent launch), as well as by tandem launch as part of several small satellites unit.

The Earth remote sensing small satellite of high spatial resolution and multispectral shooting is intended for multiregion remote sensing of the Earth surface for the purpose of:

1. obtaining the high-quality images in visible and infrared ranges of electromagnetic spectrum;

2. providing the on-line information transfer via radio channel;

3. information processing and delivery to wide range of users.

The information obtained from the small satellite could be used for performance of the following tasks:

• Monitoring of emergency situations;

• Agriculture;

• Land utilization;

• Forestry;

• Water resources monitoring.
