Hi.

My condolences to you loss.

I have two 10-20R rx´s with the latest firmware installed. The first one (with GPS) stores the nav-files with both correct date and some files dated 31.dec.2097.
I have just tested the other rx (Gyro only), and this one has stored 3 files in a row with 2097 date. Any Idea what causes this?

The GPS rx also store some very odd data in the time(s) column when watching nav files in Nav-view2.1.
Typically the first 30 seconds are displayed each second, and from then on there are stored a value on the format xxxxxx:xx (see attached image). It seems that this numbering starts as soon as the GPS is active.

I am using a Windows 7 PC to access these files..

Thanks

Best regards,
Jo

Hi Jo,
Thank you for your thoughts.
The data is only relevant when you have the GPS seeing the satellites and recording data. At any other time it usually defaults to 1970 as you can see at the top of your picture. Other than that you can ignore the dates, as there is no clock in the receiver, which would need a battery and everything sustaining it as well. It would just make things heavier etc.
Thanks,
Gerhard

Thank you Gerhard..

This makes it even stranger. If the unit has a date 1970 at each boot up, the PC uses current date and the .nav files (in Windows Explorer view) are dated 2097 and 2098
I have tried 3 different rx´s all with the same dates, all working well - so I settle with this.

I am not sure I understand the GPS part of your answer.
Are you saying that it is normal for the Time(s) column in the .nav file to stop showing seconds as soon as the GPS are locked on to satellites?
When ignoring frames without valid gps position all the sequenced time intervals are removed giving only a first cell of 0:00 before the xxxxxxxx:xx format appears.

Any idea what this Time(s) column data means: 21283867:44 ?

So no problem using my RX´s then, good to hear.

Hi Jo,
If you open the file in Nav-View, you have the option to ignore the data that does not have GPS data, or you can go into the file and delete the non-GPS-data, you will see the picture that I have attached. Then you get a continuous count from 0.00. In the box above the data you get the timestamp when it begins and the exact coordinates that you could copy into Google Maps and see where you were when the GPS started to response. That is the knowledge that I have from the GPS-system.
I hope this helps,
Gerhard

Thank you very much Gerhard.

I don´t think we get any further in this case; as we seem to be talking about different things. The box above the data looks identical, but the Time(s) columns of my files do not have a continous count.

As for the Times(s) column issue, I don´t really understand what you mean.
The left most column i NavView is labelled Time(s) and is showing a format which I don´t understand; and totally different from the example you kindly shared.
I am worried that it is something wrong with the RX as it stops the counter and switches for the xxxxxxxx:xx format as soon as the GPS locks on to satellites. It is not so tempting to use the rx in a $6400 plane if one can´t trust it´s working properly.


The file dates in Windows are a minor issue, and it seems only files from the GPS rx are stored correctly after it has connected with satellites.
But why 2097 and not 1970 as the file displays? I don´t know; a windows 7 issue maybe?

Anyway, I thank you very much four your time and effort - I really appreciate it.

I have emailed the weatronic support a while ago, but not yet received an answer - understandable given the circumstances.

Hi Jo,
Please send me one of your log files so that I can look at it on my computer. Then I can for sure tell you if there is an issue or not. ([email protected])
Thanks,
Gerhard

Hi Gerhard..

Thanks again, I have emailed you one of the log-files in question.

Best regards
Jo

Hi Gerhard..

Just checking in to be sure you received my email.
Did it reach you?

Don´t hesitate to ask if you need more files..

Best regards
Jo

Hi Jo,
Sorry for the delay, Attached are 2 screen shots that show everything is ok. I loaded the file, ignoring the data without GPS and erased the first line in the data(Just go on the first line in the data and hit delete)
The only thing that I found is that either servo 1 or 13 is running up against a stop or so and creating a bigger current at the maximum (maybe flaps). You might want to check into that. Else let me know if time and location are correct.

Regards,
Gerhard

Thank you very much for your help and patience.

It all worked out fine after your last tips..

Really appreciate it..
