Hi,
I use the TX2 as a companion computer on a drone. When I run code on the GPU, my GPS fails. I now have the Jetson wrapped in copper tape and I build a little reflector under the GPS, plus I have the GPS in about 8 cm over the Jetson. Still the problem is not really solved.
I was wondering if someone had the same problem and how he solved it. I remember seeing a TX2 drone project on an NVIDIA blog.
Thanks,
Rick
Do they share a common power source without RF isolation?
There is a UBEC and a ferrit ring on between the Jetson and the power source. But I can power the flightcontroller (which powers the GPS) completely independently (from a Laptop USB) and the Problem persists with no cable connection between the GPS/flightcontroller and the Jetson.
Hi, basically if the shielding of Jetson is good enough, there should be no RF interference to outer device. Since you have done the cover test with copper tape and problem persists still, it looks more like a power/ground issue, did you do the test with completely isolated power and ground?
I’m having the same issue. The power source is isolated. Jetson in my case Nano generates tons of RF noise. How should I approach that issue???
Same problem here for Jetson Nano. In my case the Jetson Nano interferes greatly with the GNSS signal on L2 band. Did anyone solve this problem?
As a test, can you perhaps run the TX2 inside of a grounded metal container which is separate from the GNSS? If the noise continues, then you can assume the noise is through wiring to/from the Nano, and not the Nano itself. If it is wiring, then perhaps there is a chance to examine wiring one wire at a time, e.g., simply changing the route a wire takes to/from the GNSS. If the issue does go away, then you could experiment with shields which have only partial coverage to determine which side or location the noise is predominately from (which in turn means a solution could involve a ground plane separating the Jetson on just one side).
