Abstract
A GNSS system in combination with a hydraulically-actuated, airborne dispenser for a dry material crop dusting system to optimize the distribution of dry materials over a particular tract of land. A GNSS subsystem is included using at least one GNSS antenna and one GNSS receiver located on the aircraft. The aircraft is equipped with an electronic/hydraulic crop dusting subsystem connected to a GNSS CPU. The GNSS ranging signals received by the antennas are processed by a receiver and processor system for determining the vehicle's position and dynamic attitude in three dimensions (3D). The system is adapted for operation in a differential GNSS (DGNSS) mode utilizing a base station at a fixed location.
Claims1
A global navigation satellite system (GNSS) based material distribution control system for a vehicle, which system comprises:
- a material hopper associated with the vehicle and adapted for containing a material to be distributed;
- a spreader mechanism adapted for spreading the material along a travel path of the vehicle;
- a gate box assembly connected to the hopper and the spreader mechanism;
- said gate box assembly being adapted for selectively controlling a flow of material from the hopper to the spreader mechanism;
- a GNSS subsystem mounted on the vehicle and including an antenna, a graphical user interface (GUI) and a GNSS receiver, said GNSS subsystem being adapted for providing GNSS-based positioning information for said vehicle;
- a gate box control subsystem including a controller connected to the GNSS subsystem and the gate box assembly and adapted for controlling said gate box assembly using said GNSS-based positioning information;
- a first computer having a processor and data storage;
- a second computer located at a remote location from the first computer, said second computer having a processor and data storage;
- said first computer being configured for storing field data from at least one predetermined location in said first computer data storage;
- said first computer being configured for analyzing said field data;
- said first computer being configured for generating a prescription plan for said predetermined location based upon the combination of said analysis and said field data;
- said first computer being configured for transmitting said prescription plan to said second computer;
- and
- said controller being configured to receive instructions from said second computer based upon said prescription plan.
