I got fed up with Recon Instrument new Engage-system where you cannot even download track logs to your own computer for later processing like "GPS Action replay", "GPS Speed" or ka72.com.

So I reverse engineered their file format and I've build a software to convert MOD's native data files into GPX files. Software is promising and is already working for my area. But more data is needed to validate that.

My plea for other Recon users is to provide log data elsewhere in the globe to learn how different globe areas are handled in encoding latitude and longitude.

Please send me DAYxx.RIB and EVENTxx.RIB files found on Goggles tripdata subdirectory. Before sending please check that files contain GPS log data, in other words files are longer than 9 bytes. A few kilobytes of log is fine. Please copy & send files before you connect goggles to Engage which will upload the files to server and remove them.

When I learn how North American coordinates (and hopefully South American) are encoded I'll put my software online for everybody to have GPX files of their data. Currently software works fine for Europe (Northern & Eastern hemisphere).

Here is example output of the software.

Code:

I'm htesting a kite today, will send you the data just send me your email.

Check your PM for my address.

Thanks! Chris

Thanks, I replied to your email account.

I made additional tests today and track seems to be ok. But still there are some sensor data to figure out. But that sensor data is irrelevant to track conversion.

What is already decoded, * is required for track&speed
- day *
- time *
- latitude *
- longitude *
- (doppler?) speed, unfortunately GPX 1.1 does not have speed entry so I add it to comment
- altitude *
- probably temperature, a bit irrelevant data but it is as a comment to verify

Code:
TIME      LAT       LON        SPEED    ALT    TEMP    U1  U2  U3  U4  U5
---------------------------------------------------------------------------------------------------------
12:46:31  61.507565 23.723443  16.6km/h 00091m -8C  | 197 218  45  44   0
12:46:32  61.507532 23.723522  15.7km/h 00091m -8C  | 197 219  45  44   0
12:46:33  61.507498 23.723585  17.0km/h 00091m -8C  | 197 217  45  44   0
12:46:34  61.507468 23.723658  18.1km/h 00090m -8C  | 197 230  45  44   0
12:46:35  61.507435 23.723740  18.7km/h 00090m -8C  | 197 227  45  44   0
12:46:36  61.507403 23.723810  18.5km/h 00090m -8C  | 197 225  45  44   0
12:46:37  61.507367 23.723897  19.8km/h 00090m -8C  | 197 220  45  44   0
12:46:38  61.507328 23.723965  19.8km/h 00090m -8C  | 197 222  45  44   0
12:46:39  61.507295 23.724043  20.9km/h 00090m -8C  | 197 208  45  44   0
12:46:40  61.507255 23.724113  22.0km/h 00091m -8C  | 197 217  45  44   0
12:46:41  61.507213 23.724197  23.7km/h 00089m -8C  | 197 213  45  44   0


Out of constant lenght data record there are still 5 bytes to be decoded after "|".
* U1 - The first one could be some kind of bit flags which could contain hemisphere information. It is a same for every record.
* U2 - Then unknown. It is fairly constant at range 210-230 or 21.0-23.0
* U3 - again unknown. Starts with 0 and then jumps to 46, fairly constant, range 0, 44-47.
* U4 - unknown. Flags? Only even numbers so no bit7 flag?
* U5 - always zero? record termination? gpsfix-type?

To have doppler speed as well to analysis software I am also thing of supporting NMEA output format. Currently it is only GPX.

The codebase is now fixed for global coordinates. Thanks Hardwater Kiter.

Next step is some unit conversion from metric to imperial. And doing an online version for everybody to use.

There seemed to be multiple days in single file so I quickly implemented track change at date change. I am also thinking of doing a track segment change if there is time skip for the same day.

I welcome you to convert Recon Instruments logs now. Please read the disclaimer-part for the info. Main disclaimer thing is that uploaded files will be stored on server for program improvement purposes.
