[amsat-bb] FUNcube Data Warehouse Realtime Min Max Values

[David Johnson]

Hi,

Since deployment, we have been capturing the minimum and maximum 
Realtime values for each channel when they have been uploaded by a 
groundstation. This has given us a good overview for the early operation 
and initial commisioning.

We have now moved into a steady state of operation and need to check for 
long-term trends. To achieve this, we have changed the min-max data 
collection such that it resets every 7 days and we capture the values 
each time it does so. At reset you will see the reference date change on 
the page and the min/max values converge. They will diverge again within 
an orbit.

We did think about a rolling 7 day period but that is quite a 
heavywieght process on the server as it has to be run each time we get 
an upload!

As always, many thanks to all those who are uploading data to the warehouse.

Any feedback to the forum as usual please: http://forum.funcube.org.uk
