The Multi-Band GNSS "Black box" Application Evaluation with ROCK64 SBC

Hello to Everyone!

Today we are playing with raw signal samples capturing by AmungoFx3Dumper software and testing the samples with ItsFx3 software. We have one ROCK64 low-cost single board computer in our lab. We have connected it with NUT2NT+ board and RA125 antenna, prebuilt the AmungoFx3Dumper binaries and made signal capturing from the window. Look at photo below.

You can also watch the below:

The prebuilt binaries is here. The signal captured is here, about 10 seconds, 500 MB size.

Then you can get the file out of "box" and test it by processing software offline. We are using our simple GPS correlator embedded in ItsFx3.

This small set of low-cost hardware can be used in any off-line post-processing receiver, snap-shot or continuous. The application may be: a GNSS logger for high accuracy accident reconstruction of moving object, a sensor for multi-band detection of GNSS jammers, a sensor for GNSS ground reflectometry or capturing of sensors of any nature synchronously with multi-band GNSS signals. You can strongly synchronize your own sensor data capturing with NUT2NT+ samples by using external trigger input/output.
