    Summary Precision navigation of garden tools: Today's unmanned garden tools only have the ability to move more or less randomly within the work area. With the help of new technology, precision navigation can be applied and completely new possibilities arise. Single-station and a mobile unit together enable precision control, down to the centimeter level, of motorized implements. Theft protection: Since the implement is only controlled with signals from the base unit, it is very difficult and in principle useless to steal. The base unit and the implement are in constant contact with each other. Lack of signal or position change is immediately perceived by the base unit, which can then sound the alarm. The tool can also not operate on its own. Areas of application: All types of unmanned gear where precision navigation provides advantages. Smarter lawn mowing mowing golf courses are two possible areas, but the technology opens up for a large number of applications.

    Precision control of garden tools 1 DESCRIPTION Today's unmanned garden tools only have the ability to move more or less randomly within the work area.
    GPS control is also not applicable as the precision is not, in the long run, sufficient.
    Today's robotic lawnmowers require that a restriction be placed on the outer edges of the work area. In addition, islands must be made for flower beds, fruit trees and other things that should not be cut.
    They are also very greedy for theft.
    This invention allows precision control of the implement. No action in the work area is required. The tool is in practice unused, for others, as it lacks intelligence. 2 PRINCIPLES The invention is based on, with the aid of RTK *, being able to control a tool with centimeter precision. The tool can then be given instructions, such as a numerical cutter. With control commands, the implement can be made to move exactly as the user wishes. 3 SOLUTION Two receivers each receive the navigation signals. One receiver has a given position, the other sits on the work tool. Both receivers must have a clear view upwards as the system builds on signal from GPS satellites. When the signals are compared with each other, the position, with high precision, can be calculated. This allows control down to the centimeter level.
    With software, the tool can now be made to perform its tasks in exactly the right position. For example, kangaroo lawns are cut exactly as the user wishes, grass edges are cut, aisles are sprayed and much, much more. 4 SOLUTION One unit is mounted in a given place, the other unit is mounted on the implement. Both units have the ability to communicate and thereby calculate the position of the implement. A software can then use the position indications, from the system, to steer the implement to the desired position, at the desired speed.
    Theft protection increases radically if this software is not in the implement but the implement, in addition to sending RTK data, only receives control signals. The bass system sees where the gear is located and the gear pet does not clear anything without the basic equipment, which is paired with the gear's receiver.
    *) RTK, Real Time Kinematic, is based on phase detection of carriers. _. -. - - :. ~ .w i Lmïz N

Theft protection Increases radically The software is not in the implement without the implement pet, in addition to sending position data, only receiving control signals. The bass system sees where the gear is located and the gear can do nothing without the basic equipment, which is paired with the gear's receiver. It is also easy to see if the tool stops communicating or is moved outside the approved area. Then the system can alarm and if the tool communicates, you can know where it is via the position indications.
