World's first: Statistical log reader by Ultimate Jets.
Dear all.
This is just a short article to announce that we are out of the beta phase with our new program:
The Ultimate Log Reader or ULR.
This is a World unique innovation that will enable you to get a diagnostic of your model systems in a few seconds.
The program was developed by Oistein, with my guidance.
Oistein is the code genius of our team and really is the father of this program.
He will follow up on this here.
The first stage of the program development is finished.
To keep things simple, Weatronic gave me the code to extract the data from the log files. This code was compiled by Oistein in QT libraries and then ported to the Windows platform.
The program at this stage does what Gigacontrol is offering right now with the table view and 2D view. However it adds powerful statistical analysis ( Min, Max, mean, median, stdev ).
Furthermore the program has an auto flight extraction. This means that you can load a log in ULR as long as it has a fligth in it. Then the program will extract the meaningful flight data and ditch the rest.
This data will be automatically loaded on a database hosted by Ultimate Jets. The statistical analysis will be conducted from there. The relevant RF link parameters will be isolated and presented as thsi has been explained in the Weatronic RF link diagnostic tool and blog:
http://www.ultimate-jets.net/blogs/r...iagnostic-tool
You will be able to compare your flight data with other systems around the World and verify your performance compared to others.
At a second stage, domain analysis will be added to establish system fault statistical analysis an system fatigue characterization. This will use my knowledge of airline maintenance software like Airman, Taelis, AHM/ MAT. This uses complex algorithms with domain and data frequency analysis but will not be meaningful until we get enough modelers using the system.
However I can already tell you that this platform will be able to advise you of a turbine problem and what problem is coming up ( warped combustion chamber, clogged injectors, turbine wheel performance degradation, fuel pump problem, igniter problem ). This will be available through our ASSI system that will be compatible with Weatronic telemetry as soon as the engineers from BErlin release the SCU code to us.
The platform will also be able to advise about transmitter and receiver batteries degradation, servo performance degradation, binding flight control, antenna loss of sensitivity and airspace frequency jamming.
The software will also have an automatic antenna diagram detection and antenna placement recommendation.
In the meanwhile, here are a few pictures of the actual software.
The basic data extraction:
2D view with user selectable data:
Automatic flight filtering with automatic extraction of the relevant RF link parameters:
Statistical analysis of the log:
I will come back here very soon to post a link to the program.

Looks good look forward to the link!
Your post was a lot easier to read on CHROME if you know what I mean!

Version 1.4 is out and available for download.
I have created a product page for the software:
http://www.ultimate-jets.net/collect...t-transmitters
The last version is available on this page.
I have also created an article in my technical blog where I am going to add all the features and advanced procedures available with the software.

Great Work Oli and Casten.. This certainly makes the Bat Txs more attractive.. I find it very useful to review the actual Rx received signal strength and frame numbers after a flight, especially in the early stages of test flights..

This software has many more features than a simple log reader.
It has a window that is pre-configured to show you RF link performance.
This includes an automatic flight data extraction.
Then statistical analysis is applied to the sample.
You can use Mean LQI Rx 0 and Mean LQI Rx 1 to easily check the performance of the system on the day.
Furthermore a specific battery analysis tool is also available.
All of this is explained in the user manual.
I will add more advanced procedures as we progress with the software...

Hi Oli
Nice manual!
One question I was going to ask about the P-51 files you sent me was the Rx servo movements. As the log software was beta I thought that the figures were off etc but now I have put my Yak 54 files into 1.4 software I would like to know what units etc are the Rx servo movements are in. For example when looking at DV4 it was easy to see how much servo movement you had also whether it was 100+ or 100- etc so figures I am seeing now for example are 576?

The manual looks great Oli.
Can you confirm some thing for me. Does the Gizmo Rx still record data to its own SD card when used with the Bat software.? And can these files be analysed with your log reader??

I haven't had the time to try that but I would assume so.

The functions and servo unit are a/d steps. Bat60 has a 4096 resolution so basically it is +- 2048. Servo at 100% seems to peak at +- 1260 so i guess that is what weatronic defines at 100% servo travel as servos goes beyond 100% at max.

Remember that function might not peak at exactly +-2048 and it might be slightly different on different transmitter due to calibration process. If you calibrate by holding stick hard in the extremes during calibration and use less force when operating them the max values will be lower than +-2048.

Version 1.5 is available.
http://www.ultimate-jets.net/collect...t-transmitters
It features the following improvements:
. New parsing algorithm that is a lot faster and does not interpolate between data gaps. Absence of data is shown as gaps.
. Re-calculation of the statistics when the window is re-sized on the data. This enables to extract statistical values on a short period of time.
. Mean and Median values are highlighted in bold black and bold green respectively
. Statistics available on the user plots
. The table window automatically scrolls with the RF link analysis window, enabling fast data extraction for a specific time sample number/ time stamp

IMO, this is a great improvement over the old Wea Giga Naview system, which logged "last known" values for 6 seconds, AFTER down link was lost. Weas system was very confusing, as these few seconds of data is crucial when trying to autopsy a crash.

The parser that was given to me by Weatronic was very slow because it was adding fake data to create continuity.
Oistein took some time to re-write the parser completely from scratch and optimize the code.
The result is a much faster data extraction that leaves blanks where data is missing. This also allows the ability to re-compute statistical data for any segment of time that is being scrolled through.
