Today was a gorgeous day and I followed the usual cycle trek from my home QTH out to the Humber Bay and back along the Toronto Lakeshore. Sheldon Lookout is approximately at the half way point just over the cycle bridge and there I compared readings taken on my Silva Ranger Compass, my iPhone10 and… Continue reading Position by Reciprocal Bearing

Introduction AIS Automatic Identification System for Ships is a traffic system that uses VHF transponders on vessels to periodically send out location information. It was developed by Swedish inventor Hakan Lans and is similar in concept to the ADS-B transponder system used on aircraft for position reporting. AIS uses two VHF marine channels 87B (161.975 MHz)… Continue reading AIS GMSK Modulator – Scicos Simulation

Scilab and ScicosLab are Open Source Math Programs that can be used in various engineering and scientific applications. In this post I look at how ScicosLab can be used to solve problems with the Spherical Triangle. In Celestial Navigation, problems arise in solving the Plane Triangle and also the Spherical Triangle. Video ScicosLab for the… Continue reading Scilab & ScicosLab – Open Source Math for the Spherical Triangle
