SARMobileAirNav Beta Submitted to AppWorld

It has been a long haul, but SARMobileAirNav has finally been submitted to AppWorldl. This is our first submission to AppWorld so there may be a few more hurdles to get over, but if all goes well it should be available for download. It will be free while in Beta. We will review the pricing structure (if any) once we are happy with the finished product.

SARMobileAirNav with OurAirports.Com Data

An aviation navigation program is nothing without a database of aviation data. OurAirports.Com provides this data in the public domain. The data is free, which is nice, and good quality, both important features. But one thine that is important to us developing a program to support search and rescue it that it captures a wealth of local data the won't be found in the commercial data sets. Knowing about Maxville, or Howick may make a difference during a search.

The SQLite3 database file is available for download at:

Aural Null Simulator Screen Shots

Here are some screen shots of SARMobile.Ca AirNav program running in Aural Null simulator mode. This is an Aural Null Procedure A which took about 1 hour 20 minutes to complete from first detection of the ELT until overflight of the computed location.

The magenta circles are the aural null detection points captured as the ELT signal is first heard. The green squares are convenience way points marked when the signal is lost. This just allows for planning the turn to re-acquire the signal and capture the aural null point.

The simulated ELT was at N 45 10 W 76 20, and here is the Aural Null calculation screen showing a 2dRMS of 0.11 nm:
