If you have GPSResults you can save the file as a .sbp or .sbn file and then GPSAR will be able to read it. It is the native .sbp file from the GW60 it has trouble with.
Roo, just to back and re-read Patrick's post. He wrote:
"GpsArPro doesn't show my 10sec runs, logged at 5hz. To see them I have to uncheck the "Cubic enabled" box." There is no general problem reading GW60 files. Nor is there a problem calculating 10 second speeds with "Cubic" unchecked. GPSAR has all the data it needs; it's just a specific algorithm that fails (most likely because it assumes 1 Hz data).
This specific problem can be seen with 5 Hz .sbp data from GW60 and GW52s, with 5 Hz .ubx data files from the Flysight, and (according to JHdeBruin) with 18 Hz data from the Gyro1. The problem exists regardless of whether the "Doppler" box is checked or not. Opening the files in GPSResults and saving them to a new .sbp file does
not help, the problem persists. The problem also persists when converting files to .gpx files. This is obviously a
different issue than the one problem you had encountered with your U-Blox GPS data.
It's great that you know which GPS chip is used inside the watch, and what the communication between the chip and the firmware is. I find it interesting that they switched to MTK chipsets. But which chip they use is completely irrelevant for this particular problem.
