The GPS simulator project gps-sdr-sim now supports ADALM-Pluto SDR for playing IQ data.
In upgrade 1 I described how to add a GPS to the ADSB receiver for a precise clock in the Raspberry Pi. Here is another description how to add a graph in the the ADSB receiver portal for monitoring clock performance.
The ADSB receiver OS image that I use provides several performance graphs including the CPU temperature. For receivers installed on a remote location that is maybe not enough to monitor what´s going on inside and outside the box. For that reason I decided to install additional temperature sensors in my ADSB receiver box. My choice was the the Dallas DS1820 1-wire temperature sensor. It´s easy to interface to an Raspberry Pi and the kernel comes already with drivers. Perfect for that purpose.
This upgrade is divided into two steps: 1. Connect the DS1820 to the Raspberry Pi and configure the kernel drivers – 2. Reconfiguring the collectd service and the shell script that is creating the performance graph so that the additional temperatures will be logged and plotted as well.
