Welcome to the FUNcube Web Site

The FUNcube team were interested to know the trend of the number of uploads to the warehouse since launch, we thought we would share our findings:

~~. FUNcube AO-73 Upload Trend

We have been consistently getting more than 5000 raw packets per day and the trend is increasing, thanks folks!

The plan is to issue this on a monthly basis.

The FUNcube Data Warehouse is now producing .csv files containing Realtime data channels.

The data is produced every hour, on the hour and contains 3000 rows, starting 250 minutes before the last record in the database.

As we do not have worlwide coverage, there will be missing segments of data. To overcome this, we fill the data with the last value before the gap.

All records are have an associated ‘satellite time’ this is based on the known activation time of the satellite and offset calculated from the sequence number and frame type. The satellite is currently 3 hours 50 minutes ahead of the data server time.

Please visit the Real Time Data page and click on the link in the descriptive text.

We welcome feedback on the format and content. Please use the forum:

Please note that we have dropped the https/ssl protocol because we are making the site open to all. I.e. there will be no requirement for a login/password for any of the site functionality.

Users will still be required to register their basic site and location information to allow them to upload data to the Warehouse from the Dashboard

There may be a few pages that look a little strange while we make the transition.

The URL is now:

http://warehouse.funcube.org.uk rather than https://warehouse.funcube.org.uk

Any problems, please report them on the FUNcube forum:

Hi,

As promised, we are making the High Resolution Data available for download here

It contains Hi-Res data generated every hour, on the hour for the 60 minutes preceding the extract.

Please note that unlike the Whole Orbit Data, the Hi-Res data may be incomplete (have significant gaps) because of a lack of ground stations on the ground track.

Now that we have the WOD and Hi-Res extracts working, we are going to move on to the RealTime extract.

Please provide any feedback on the FUNcube forum

73 and Happy New Year,

Hi,

I am doing some tests with the Data Warehouse upload service today. You may experience
some outages to the service for about a minute at a time while I the swap loaders.

The Warehouse User Interface will continue to function during these tests.

FYI, the raw data recovered and stored in the warehouse is about 1.4MB per day plus the FEC overhead!

Hi,

We are extremely grateful to all the groups and individuals who have uploaded data to the warehouse and the totals on the upload ranking page are quite amazing.

Since launch we have been monitoring the service which receives, processes and stores that data and now are about to make some changes to it to improve it performance and reliablity.

The first change is to introduce an acceptance time window for packets uploaded from the Dashboard. This restricts packets to those whose sequence numbers are within +/- 48 hours of the latest sequence number stored in the warehouse. We are doing this for two reasons:

1. We have received erroneous packets whose sequence numbers are significantly different to the latest value.
2. To reduce the chance of double scoring of points when we release stored data back to the user community

The second change, which will not affect normal operation but will improve scoring:

• We currently process packets immediaely they arrive at the server. Under load, this can cause us to lose a few packet scores because of contention in the database. To alleviate this problem, we are going to change the processing slightly to process packets through a buffer. This buffer will be processed every 5 seconds, so there will be a slight delay
  before packets are acknowledged on the ranking.

The FUNcube Team are pleased to announce the latest version of the Dashboard Software.

Version 814 can be downloaded from https://funcube.org.uk/working-documents/funcube-telemetry-dashboard/

We thank everyone for their interest and reports of the success of FUNcube-1/AO73 and we look forward to continued operations.

Wishing you all a very Happy Christmas

The FUNcube Project Team.

We have now added the facility to view the latest High Resolution Data uploaded to the Data Warehouse. The link can be found in the Navigation Bar on the warehouse.

These are example of what the data will look like:

Sun Sensors

Total Photo Current

Battery Volts

Following on from this will be making Hi-Res data available to download via ..csv files, in a similar way we do for Whole Orbit Data. Watch this space.

Seasons Greetings
