RTL-SDR for NOAA15/18/19 Satellite Weather_b


In previous posts several years ago, I looked at receiving NOAA15/18/19 satellite weather using various configurations with a Windows 10 laptop and a RaspberrPi4 (Ref.1/4). To bring in the new year, I thought I would check out the latest reception. In the last post I used SDR# with noaa_apt & wxtoimg (Ref.1). In this post I will use Multipsk to do the reception and the decoding (Ref.6).

Equipment Setup

Figure 1 shows the equipment setup for receiving NOAA15/18/19 satellite weather. In order to receive signals of adequate strength, a LNA/BPF is required. A 1/4 wave Vee dipole is used with a version 3 RTL-SDR with BiasT to power the LAN/BPF. Signals are received using Multipsk to control the RTL-SDR and are decoded as well. Figure 2 shows the RTL-SDR transceiver control at the bottom receiving the FM baseband of 2.4KHz harmonics. The upper portion shows the decoded 2.4KHz AM modulated tone.

Figure 3 shows the built-in Multipsk Satellite Tracker. By entering your position, it can tell you the location of the NOAA15/18/19 satellites as well as Pass data. Figure 4 shows the N2YO Satellite tracker used in previous posts (Ref.7). Figure shows the NOAA19 decoded APT image. Note that I am in an urban location with very restricted visibility due to high condo buildings (East only view).
