some further analysis of the rover obs shows 3 strange epochs with a
sharp 6 seconds (subframe) error, e.g.
> 2016 04 03 13 14 55.600000 0 11
*> 2016 04 03 13 14 40.800000 0 11**
*> 2016 04 03 13 14 56.000000 0 13
please check your converter as the rinex also reports several CRC
failures causing solution gaps
1. the Doppler shifts reveal a 2ppm error in the crystal which is
uncommon (to say the least) for LEA-6T.
2. the C/N0s peak at 40dBHz which is symptom of a very poor antenna.
3. the range inter-satellite differences shows incorrect range behaviour
for SV 8, 12, 20, 27 around 13:13 which is very odd, looking like the a
clock jump not being handled correctly on all satellites .. are we sure
this is a uBlox?
