METHOD OF OPERATION OF PLANT PROTECTION UNIT WITH SATELLITE NAVIGATION ON AGRICULTURAL FIELDS Russian patent published in 2013 - IPC A01G13/00 A01M7/00 A01G25/16 A01G25/09 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. In the method the plant protection unit is operated, which consists of the vehicle and the sprayer with nozzles for spraying agent of protection. The operation of the movement of plant protection unit is performed by the onboard computer with the navigation system in accordance with coordinates of the route inputted in the onboard computer. The operation of spraying is carried out by using the nozzles of the sprayer in untreated areas of the field. At that operation of spraying is carried out by using the nozzle of the sprayer in untreated contaminated areas of the field to be sprayed - the contaminated area. The operation of the plant protection unit, movement and choice of the route geometry of movement, positioning accuracy of the unit on the route, the length of the rod, the number of nozzles on the rod, the radius of nozzle discharge pattern, the criterion for inclusion of the nozzles and operation of spraying is carried out with a minimum of environmental damage, and power resources costs of the plant protection unit, taking into account the spatial position of the contaminated zones and field configuration for a given precision of navigation and the system of determining the geographical coordinates.

EFFECT: method enables to minimise environmental damage and power resources costs for operation of the plant protection unit by reducing the length of the route of movement of the unit on sites including the contamination zones.
