If you already have the title and abstract for your article, you can use the following tools from Elsevier and Springer to help you pick a right journal among those that belong to the respective publisher

http://journalfinder.elsevier.com http://journalsuggester.springer.com

The output of these tools shows inter alia average article processing times and impact factors of the journals and, if I recall correctly, also publication fees and open access fees.

In many journals you can publish *free of charge* if you do NOT make your article open access (i.e. it is available only to journal subscribers), but this should be checked for each journal separately.

Once you make a short list of potentially suitable journals, you can check whether they are covered by Scopus here

and by Web of Science

Indersience and IEEE Transactions on Aerospace and Electronic Systems are mostly free.

To Prof. Artur Sergyeyev and Prof.Srikanth Kavirayani,

Many thanks for your rapid answer.

Effectively some journals of Elsevier don't charge now to authors if they don't request open access.

About the third web site Prof. Artur Sergyeyev provides: https://mjl.clarivate.com: firefox declare it unsafe, is it normal?

Again thanks,
