Overview of System

The DynaFlight-AirAgII™ system is a GPS based electronic guidance and data management system specifically
designed as a tool for the pilot to fly parallel swath guidance for the application of seeds, fertilizer and chemicals for
farm and forestry applications. It also gives guidance to return back to the job to continue his application after refill.
The system automatically senses spray on and spray off for recording and displaying the real time map of the
application and displays this to the pilot in his heads up display. The system comes with a built in satellite
differential.

Mounting

GPS Antenna

Overview

As the GPS antenna has two functions, one, to view the full constellation of orbiting satellites and two, to
view the geo-stationary differential broadcast satellite positioned over the equator, the antenna should have
as much visibility of the full sky as possible.
Placement – IMPORTANT!! Make sure that the GPS Antenna is bonded to the Airframe.
The GPS antenna should be mounted on top of the aircraft/helicopter and should take into consideration
the following. See figures 1, & 2:
On helicopters, mount the antenna as far forward on the top as possible while keeping the antenna as flat to
the horizon as possible. This is to keep it away from the rotor mast as much as possible as well as lead the
pilot to the spot.
The antenna should be mounted high enough to see as much of the sky above and around so as the
fuselage does not block the signal and as far forward as possible.
Mounting on the tail would be a last resort and should only be done if Laser Gyro option is installed in the
DynaFlight.
Keep as far away from transmitting antennas as possible (at least 12 inches) If this is not possible, please
contact DynaNav for recommendations.
