THE SOFTWARE FEATURES: • Real-time 3D navigation program • Pre-flight simulator and planning program • Utilities for uploading and downloading data • Set up survey area • Define line direction • Automatically generate flight lines to cover area • Rotate area in direction of flight • Four flying modes: Map, Grid, Line, Waypoints • 3D guidance LINAV Precision Navigation System The LiNav is a DGPS navigation system designed to meet the specific requirements for general aerial survey. The LiNav system provides the pilot with swath, directional guidance, and other navigational information required to carry out precise aerial applications. The LiNav consists of a compact, intelligent Moving Map Display with keypad, a choice of AG-NAV's light bars (steering indicators) to suit the application and type of aircraft, and a stand-alone DGPS receiver system. The LiNav system is used with a variety of DGPS receivers incorporating OmniStar L-Band satellite differential or WAAS and/or Coast Guard Beacon. LiNav uses the popular PNAV software with customized data output that has proven user-friendly and successful in general survey application.

LINAV Precision Navigation System How It Works Theory: LINAV 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 (or altitude) reference is obtained from a gridded (using Geosoft) image of the area. Reference Grid File: The reference altitude grid file can be generated using various methods. 1. Tie Lines of the survey area can be flown and the GPS altitude data gridded using Geosoft. This Tie Line Grid file can then...
