EAGLE_528

Ground-to-Aircraft Radio Link Analysis

 

Eagle_528 is a PC program useful to estimate link budget, path loss, and link reliability of a Ground-to-Aircraft radio link in the VHF, UHF, and SHF frequency bands.  Path Loss estimates are based on the model given by ITU-R Rec. P.528-4 (2019).  Several tools are provided to process such estimates and to display results in a practical style.

 

Main Functions :

 

*  Definition of Ground Station Data (to be saved in the Ground Station library);

 

*  Definition of Radio Link parameters (Ground Station and Aircraft);

 

*  Link analysis (Link budget report and various diagrams);

 

*  Display of 360 deg Radio Horizon around the Ground Station;

 

*  Radio Link data stored for further analysis and updates.

 

 

Eagle_528 key benefits:

 

*  Easy and fast check of up- and down-link reliability for any aircraft position (distance from ground station up to 1000km, height up to 10,000m) and for frequency range from 120 to 15,000 MHz

 

*  Use of NASA/SRTM maps (free download, 1 or 3 arcsec raster resolution) for radio horizon estimate

 

*  Multiple diagrams for intuitive link performance representation:

 

*  Link reliability vs. distance (for given aircraft heights);

*  Maximum distance vs. reliability objective;

*  Distance / Height maps giving Link Margin or Link Reliability in a colored scale.

*  Multipath Outage; Rain Unavailability;

 

*  Interference analysis;

 

*  Passive repeaters;

 

*  One-click access to Background Theory.

 

Significant Features :

 

*  Import of SRTM (NASA) terrain maps, and of ASTER (NASA/METI, Japan) maps

 

*  Interface to Google Earth to import / export network topology

 

*  Update to the most recent ITU-R Recs (P.530, P.838, P.527 ...)

 

*  Comparison of predicted performance with ITU-R or North America performance objectives

 

*  Reading Antenna diagrams from NSMA (ASCII) files

 

*  Crane rain attenuation model (in addition to ITU-R model)
