Satellites in Agriculture

Nowadays it is hard to impress somebody with satellite launching. Though just 60 years ago it was like a fantastic tale. Nobody thought that it can be possible to see the photos of your house, street or field made from the space. In this article the issue of modern achievement, which became available thanks to satellite systems  and their influence on agrarian business will be discussed.

Achievement 1. Navigation.

Due to satellites the system of navigation GPS, which is now used for determination of  location and direction on air (aircrafts), on water (ships), and on land became possible. An advantage of this system is that it provides opportunity for any place (excluding polar region), almost in all weather conditions, to indicate the speed and  objects location. The basic principle here – the determination of the location by measuring the reception time of the synchronized signal from satellite to the consumer.

Achievement 2. Weather and climate control.

Satellites give possibility to explore the weather around the world, allowing them to follow the effects of phenomena like volcanic eruptions and burning gas and oil fields.

Satellites are the best sources of data for climate changes research. Satellites monitor ocean temperatures and prevailing currents; rise/drop of the sea levels, the changing sizes of glaciers. Satellites can determine long-term patterns of rainfall, vegetation cover, and emissions of greenhouse gases.

Achievement 3. Land Stewardship

Satellites can detect underground water and mineral sources; monitor the transfer of nutrients and contaminants from land into waterways, and the erosion of topsoil from land. They can efficiently monitor large-scale infrastructure, for example fuel pipelines that need to be checked for leaks.

As we can see, satellites have changed both: our leisure time and business, provoked the emergence of new agricultural technologies. We got possibility of more accurate prediction of changes in climate and weather, which is very important for farmers. Satellites have made possible simplification and improvement of the process of soil nitrogen saturation. We would like to highlight the following:


You can equip the tractor with signal receiver GPS, heading sensor and controller – the screen that reflects the identity or deviation from the path of the tractor predetermined. The control system allows you to store and forward rate tractor strictly parallel to the line that is fixed on the first pass of the unit, the second option – autopilot, which consists of electro-hydraulic automatic control of the tractor, which provides tractor autopilot on the field. Tractor-driver helps the process only while cornering, allowing it to focus on the process and less physically tired.

GIS (Geographic information system) – the system of collection, storage, analysis and graphical visualization of spatial (geographical) data and related information on the necessary facilities.

A new and promising directions in agriculture abroad is precision agriculture. The concern is that to use the heterogeneous data (the geographically-referenced results of soil sampling, remote sensing data processing, digital thematic maps) to optimize decision-making on the local application of fertilizers and pesticides into the soil to boost agricultural productivity.

2. Satellite crop monitoring

Technology based on spectral analysis of high resolution satellite crop images which enables to monitor vegetation developments, soil temperature,  humidity and to reveal problem areas on the field. Satellite crop monitoring is also suitable to precise weather forecast based on concrete field coordinates and to recall historical weather data retrospection. Discrepancy in NDVI dynamics reports about the disparities in development within a corn or a field that indicates the need for additional agricultural activities in some areas.

In conclusion, we can say that due to modern technologies as satellites we construct our future, and in order to go with the times it is very important to know about them and to use them, because combination of them with your experience make your business more efficient and with less time and effort costly.
