I have a uBlox UP501 it's not good but not as bad as some for jitter. it works very well with vlfrx-tools (haven't looked at the code, but probably Paul included some magic code to average out jitter). Speclabs magic interpolates the 1PPS pulse but I can still see jitter from the modules that have it, I was wondering if would cause problems. I had to work on my Trimble in order to use it but it is solid. 73 Eddie G3ZJO |
