Introduction In recent posts I have been looking at using my new GNSS receiver on various maps such as OpenStreetMap and OpenCPN (Ref.1/4). Yesterday I received an email from a colleague who told me about AIS Catcher, a new multi-platform AIS software (Ref.5). I downloaded it and tested it from my home QTH. Tech Minds… Continue reading GNSS & AIScatcher on OpenCPN

Propagation Testing with GNSS on OpenStreetMap
Introduction In the previous post I did a walkabout to test the propagation testing equipment on OpenStreetMap (Ref.1). In this post I do the same thing but actually drive over a greater portion of the map area. For reference purposes I use Toronto Marine Weather at 162.4MHz as the test signal. Equipment Block Diagram Figure… Continue reading Propagation Testing with GNSS on OpenStreetMap
GNSS on OpenStreetMap
Introduction Several years ago I read an interesting article on how to marry your spectrum analyzer, GPS and map software to do a propagation drive test (Ref.1). In previous posts I looked at using a new GNSS receiver for use with Radio Mobile for propagation testing (Ref.2). So in this post I will incorporate the… Continue reading GNSS on OpenStreetMap
GNSS Receiver
Introduction In the previous post I reviewed my existing GPS receivers and took a quick look at a new GPS/GNSS receiver BU-353N5 (Ref.1). In this post I am going to look more carefully at this new GNSS receiver and its capabilities. GNSS = Global Navigation Satellite System (Ref.2). GNSS Systems Satellite Navigation System Properties GPS… Continue reading GNSS Receiver
GPS/GNSS Receiver Testing
Introduction Recently I have been looking at propagation prediction. I read a very interesting article about propagation drive testing, so I thought I would check my existing GPS units for suitability. Since I replaced my Win7 laptop with a Win10 laptop several years ago, a key thing changed. The original FTDI drivers for various devices… Continue reading GPS/GNSS Receiver Testing
