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
RTL-SDR for Satellite Weather on GOES16 – Signal Decoding
Introduction In the previous two posts we looked at planning for reception of GOES16 weather signals and we did a signal capture as shown above. Improved performance resulted when the LMR400 coax was inserted between the SAWBIRD Filter/LNA at the back of the antenna and the RTL-SDR . From the first planning post, the average… Continue reading RTL-SDR for Satellite Weather on GOES16 – Signal Decoding
RTL-SDR for Satellite Weather on GOES16 – Signal Capture
Introduction In the previous post we looked at planning for reception of GOES16(R) weather signals. We determined a ball-park estimate of a received level at -84dBm (assuming a satellite transmit power of 60dBmi) at an azimuth of 174deg and elevation angle of 39.4deg for a location in Toronto, Canada. Signal Capture for GOES16(R) Figure 1… Continue reading RTL-SDR for Satellite Weather on GOES16 – Signal Capture
