GPS weather data recording system for use with the application of chemicals to agricultural fields

摘要

A GPS weather data recording system for use with the dispensing of chemicals to agriculture fields. A GPS receiver is used to determine a series of positions of a vehicle and the velocity of the vehicle as the vehicle traverses an agricultural field. The series of positions and velocity trace the vehicle's ground track across the agricultural field. A wind sensor is used to measure wind velocity with respect to the vehicle. A data storage system is used for storing data measurements, such as the series of positions from the GPS receiver and a series of corresponding wind measurements from the wind sensor. A computer system is coupled to the data storage system. The computer system receives the series of vehicle positions and velocity from the GPS receiver and receives wind velocity measurements from the wind sensor. The computer system is configured to store the series of positions and the corresponding series of wind velocity measurements into the data storage system such that a record of the true wind velocity with respect to the vehicle position is created. The record can be referenced with respect to time to show the vehicle's position on the field at a given time and the true wind velocity computations corresponding to that position and time.
