ADS-B Out Basics

Introduction ADS-B Automatic Dependent Surveillance Broadcast (Ref.1) is an avionics system that allows planes to transmit their navigational status on a periodic basis without interrogation. It is an outgrowth of the ATCRBS Air Traffic Control Remote Beacon System – Mode A, Mode C and Mode S (Ref.2). It is a particular case of Mode S… Continue reading ADS-B Out Basics

RTL-SDR for ADS-B with MultiPSK on Local Map

Introduction In the latest version of MultiPSK (Ref.1) there is a facility for displaying decoded ADS-B information on a user defined map. In the previous post we examined displaying AIS & ADS-B on OpenCPN. The only problem there, is that ADS-B information is not native to OpenCPN, so only the Lat/Long is preserved. In this… Continue reading RTL-SDR for ADS-B with MultiPSK on Local Map

RTL-SDR for AIS & ADS-B on OpenCPN

Introduction Recently I was approached by several different parties inquiring whether AIS and ADS-B contacts could be shown on the same chart. Over the past year, I posted on several different forums asking whether this could be done, so my interest was re-ignited. The immediate application for this is for an off shore oil/exploration rig,… Continue reading RTL-SDR for AIS & ADS-B on OpenCPN

RTL-SDR for Satellite Weather on GOES16 – Image Capture

Introduction In the previous three posts we looked at planning for reception of GOES16 weather signals, signal capture and signal decoding. In this post we use a temporary dish support to receive GOES16 over a short time period by keeping the Viterbi error rate as low as possible. Due to the author’s location, a rigid… Continue reading RTL-SDR for Satellite Weather on GOES16 – Image Capture
