AG-NAV LiNav
TAKE YOUR SURVEYING TO THE NEXT LEVEL
The LiNav is a precision navigation system designed for aerial surveying.
Plan Your Flight
LiNav features pre-flight planning and training programs. This allows you to set up your survey area and parameters before your flight. The Training program gets you familiar with the system, learn all tasks you will do, prepare for the flight and fly with confidence.Precise Guidance
With accurate DGPS data, LiNav keeps pilots on track with its four flying modes and attachable lightbars. It features 3D guidance and altitude profile display along the target flight line. It also displays on screen the information related to your surveying application.Powerful Software
The LiNav software has proven to be user-friendly and successful in the aerial surveying industry for 30 years. LiNav outputs customized data to data acquisition system; and can record flight data for merging with your survey data for post flight analysis.FEATURE LIST
HOW IT WORKS
The LiNav system uses a horizontal cross-track indicator for XY (left/right) directions and a vertical bar for the Z direction (altitude).
Horizontal navigation is performed using a pre-defined Flight Plan as a horizontal reference. The vertical reference is obtained from altitude profile over the survey area.
The horizontal guidance is shown both on the main screen and an external lightbar. The vertical guidance is shown on a vertical bar on screen, and external vertical lightbar if selected. This vertical bar indicates the difference between the aircraft altitude and the target altitude.

Drape or altitude gridded file (*.grd) stores altitude reference, either at ground level or desired flight height. A drape file can be generated using various methods:
1. Make a tie line file over the survey area. Fly these tie lines at desired altitude. Use Geosoft software to grid the GPS altitude data. This Tie Line file can then be used by LINAV to provide pilots with exact vertical navigation to ensure Tie Lines intersect Survey Lines.
2. USGS 30 arc second digital elevation data can be purchased from the internet. This data should then be gridded using Geosoft and used by the Navigation system as an accurate vertical navigation reference.
3. Any other local “digital elevation data” converted into a Geosoft grid file can also be used.
Note that when using Geosoft, the Axis Rotation must be zero. If the altitude data in a drape file is mean sea level, then the vertical data for LiNav must be GPS altitude. If the height above ground is used, the vertical data for LINAV must be from a laser or radar altimeter.

The LINAV records flight data if selected. The data includes GPS time, Lat/Long, X/Y, altitude, flight line number, cross track error, altitude difference, and other GPS information.
The flight data files can then be imported into SurvView for flight replay, printing, converting to other file formats for analysis using other GIS software.
The LiNav has proven for years to be user-friendly and successful in all applications that require accurate navigation. With excellent support from AG-NAV, you will feel that we are always with you to find the best solution for your challenges.
