VOACAP Online now offers multiple coverage maps at one go

The VOACAP Online Coverage Maps Service at is now able to plot multiple coverage maps at one go. This was made possible by a major code re-factoring at Earlier, only one map could be plotted at a time.

In a nutshell, while entering the input values, at "Time UTC:", choose the start time for your maps. The default is the currect UTC hour. See image below.

Then there is a pop-up menu for "Period". There you will need to choose the time period for your maps, defaulting to 1, i.e. the map for the current hour. You can choose a time period up to 12 hours, so to cover a 24-hour period, you will only need to make two runs. Unfortunately, running and plotting 24 hours, or 24 coverage maps, at one go takes a considerable amount of time, resulting in a server connection time-out, hence 12 hours is the limit.

So when viewing the result page with the maps, you can then conveniently print that page to PDF. You may need to install some extra tools such as CutePDF Writer if this functionality is not offered to you by your operating system as standard.

Please be also advised that all the coverage maps created in the service will be deleted in a more frequent cycle than before so please do not link directly to the maps produced.

Also, earlier this month, I added the option of choosing the noise level at RX sites. This option was also added to VOACAP Online Point-to-Point Service.

Give it a spin and let me know what you think!
