Pulled base receiver legs before turning power off, trimming bad data
OK, Paul, that triggers two ideas - 1) Contact Hemisphere (manufacturer of BRx7) to see if the native BIN file might have such an indicator, and 2) Contact Carlson to see if the RW5 might have an indicator. I'll post my results here for others. Thanks.
Even though you got a solution it could be biased by the extra data.
It seems that when I once ran a session through the Canadian NRC site it gave me a graph of position vs time. That would let you identify the beginning of movement, so you could chop off that much of a RINEX file and resubmit to OPUS.
I ran your file as a kinematic observation file, processed against MASH and I can't see that the receiver moved during the observation. I don't think you have anything to worry about.
The results are attached...
3 minutes of 30 s epochs would be 4-5 pings vs the total number over the course of the session. Probably didn’t cause a significant variation in the session.
