I collected static data for the second time and again did not obtain a solution from any of the 4 control points when uploaded to OPUS rapid static.ย I am using an R7 with a zephyr 2 gnss antenna.ย The area I am collected is a somewhat clear area within a deciduous (no leaves) wooded area.ย At least 10 satellites were tracked the entire time for all of the collection sessions.ย I am pondering three things:ย 1. Should I try to collect for a longer period - maybe even 2 hours or more and upload to OPUS static processing?ย 2. Should I be using a zephyr 2 geodetic gnss antenna?ย 3. Is there software out there that will enable me to "weed out" bad collection epochs?ย I have tried collection at 1, 5, 10 and 15 second invervals for over 30 minutes each control point.ย Any input would be greatly appreciated!ย thank you.ย ย ย All points come back with 1 of 2 of the below error messages from OPUS:

ย 6034ย ย ATTENTION!! The quality of the GPS data from the rover or nearby
ย 6034ย ย CORS sites was too noisy and below minimum standards to attain a
ย 6034ย ย meaningful solution. To avoid this unexpected inconvenience the
ย 6034ย ย user may want to re-observe at a different hour of the day and for
ย 6034ย ย a longer period of time.

ย 6009ย ย The OPUS-RS solution for the position of the rover has
ย 6009ย ย failed to converge after 5 iterations. This could be due to
ย 6009ย ย especially noisy data (among other reasons). If you really need
ย 6009ย ย a position for this station, you might try another data set.
