What is the function of a GPS system in aerial application?

The function of a GPS system in aerial application is primarily focused on improving accuracy in targeting specific areas and maintaining application patterns. With a GPS system, aerial applicators can precisely map out the fields and identify specific locations where treatments need to be applied. This precision helps ensure that the application is done efficiently, covering only the intended areas while minimizing the risk of overspray or underapplication, which can lead to ineffective pest or disease control.

Additionally, GPS technology allows for the maintenance of consistent flight paths during the application process, which is crucial for uniform coverage and effectiveness. By using GPS, applicators can also log data for future reference, creating a more efficient workflow and better planning for ongoing treatments.

As for the other options, while communication and tracking costs are important aspects of aerial application management, they do not specifically tie into the primary function of GPS technology in this context. GPS is fundamentally about the accurate placement of applications rather than managing operational costs or communication logistics.
