Thank you rgschmidt for the update!

Fantastic!

Can you please email one or more of these 1000 cache PQ's to webmaster at GPSrChive dot com?

Thank you!

Also, if you don't want to wait, and you updated the other 64st units with Garmin Express on a Windows PC... Navigate to the " C:\ProgramData\Garmin\CoreService\Downloads\PrimaryFirmware\ " directory and then find the folder with the correct firmware version for the GPSr you want the updat...

That firmware version has been in beta for a few weeks now. When Garmin publishes non-beta firmware updates, their servers are configured to send them out in 'batches.' It is entirely possible the unit ID for the 66s you have just isn't part of one of those 'batches' just yet. Give it a few days, an...

However, the data we have looked at using the Trimble tool is with the Elevation cutoff set to zero i.e. perfect conditions. If one simulates more difficult conditions with satellite obstruction by incrementally raising this elevation mask, with a single GNSS, one soon gets to a situation where the...

Thank you for the update!

I tried "Auto Calibration = Once". The device did not get a near correct barometric altitude upon power-up. The figures were: GPS = 103m (correct) and barometric 195m. Please see the post above by 987. If you are certain of the elevation value for a given location, manually calibrate the ...

It may also be a long standing bug that needs to be corrected for all devices that record FIT files....

This recent article entitled "Comparative Study on GNSS Positioning Systems for Autonomous Vessels in the Arctic Region" should be of interest to your research: http://ceur-ws.org/Vol-2626/paper12.pdf That is an interesting GNSS simulation study. I have also been researching GNSS availabi...
