lease excuse my bad English and hope that someone helps me anyway.
I have a 5Hz GPS Expander V3 and eLogger V3 and while I generally like them, there are features that just don't work as they should. The basic volts, amps, functions are awesome, but other issues are listed below.
6.33 software is installed, and all devices were updated with the latest firmware via 6.33 software.

I want in a glider with GPS modules that record data. I have made many attempts in a car. When I set the CR 10PS, I get results from the 10PS 5 without error and 5 Identical GPS positions with errors. This Ok because I think the GPS Expander 5Hz. When I set the CR 2PS, I expect 2 results without error (average of 5 internal measurements).
Practically I just get a good measurement per second is equal to the 2nd of error. (The EventError = 18)

Sample with CR 2PS

It follows that problem a very short loggertime. If I 2 good measurements per sec do I want to have the CR 4PS.
Does that for you without this error?

HI Geni,

Sorry about your issue. I think I understand what you are asking. With version 6.43, there are improvments in how often GPS samples are logged with sample rates lower than 8 samples per second. Could you please try this version:

Bill, for Eagle Tree

Hi Bill,
Thank you for the quick response. Now i use the version 6.43.
1st Here is the result of my tests, now have all the errorcode 18 although NumSats> = 9 and GPSFlags = 7. I think it is a step in the right direction.
2nd The Logtime of 202 seconds was 405 Records, and will need 10% from memory. If this is not a low level of efficiency?

Hi Geni,

Glad the main issue has been resolved for you.

Regarding log time, we are going to enable our lossless compression on the GPS data, which will greatly increase logging time. We will do this as soon as possible.

Regards,

Bill, for Eagle Tree

Hi Bill,
you are very fast.

Manual page9

18 = ERROR_GPS_DATA_PACKET: GPS Data was received from the GPS Expander

How do I interpret the error 18? So i'm not sure!

Thats a very good message.

Hi Geni,

The error 18 just means that GPS data has been received for that sample. It is a good thing. :-)

Bill, for Eagle Tree

My measurement of today with 1 per sec. Total 3 sessions.
Distance between start and end of 40km and all records have the same value. This can not agree. I understand the world no longer. Is 1 per second measurement is not possible?

Geni

How is the status?
1. The log time with GPS is still very short.
2. When will the Optimal capturerate 5/s supported?

Geni
