GRSL is published only in English, and the use of correct English is required of all authors. Thus, contributors for whom English is not a native language should have their papers edited for style, form, grammar, and spelling suitable for publication prior to submittal to GRSL. Authors who would like assistance with English grammar and usage prior to submitting their manuscripts for review or during the review process can go tohttp://www.prof-editing.com/ieee to submit a manuscript for copy editing by SPi. SPi copy editors will edit for grammar, usage, organization, and clarity, querying potentially substantive revisions as necessary. Authors can use the service, at their own expense, as often as desired. Cost estimates are available on line, typically $100 for a four-page article. Edited manuscripts will generally be returned to the author within two weeks of submission.
