Note 1: The forms of this journal are in the forms and necessary files section.

The authors of English papers must submit their manuscript in Microsoft Word 2016.

General:The entire manuscript, including abstract, nomenclature, footnotes, references, figure captions and appendixes, must be 10-point type, Single, with 25 mm margins all around. Make the headings short but informative (specific), in boldface, centered, capitalized and numbered with Arabic numerals. Make sure that each sentence is clear and unambiguous, and that paragraphs are of reasonable length.

Tables: Plan tables to fit the column width of the journal (8.5 cm) or, if necessary, the page width (17 cm). Each table must have an arabic number and a caption (definitive title) at the top. Tables (and figures) should occur in reasonably close proximity to the text that refers to them and should not repeat information available elsewhere in the paper. Fonts smaller than 10 pt should be avoided.

Figures: Figures should be of good quality and with adequate description. All lettering must be sized so that it will be at least 8 points high when the figure is reduced to column width (8.5 cm); avoid variations in lettering size. All lines and graph points must be distinct. Figures should appear within the text, close to where they are cited. Each Figure must have an Arabic number and a caption (definitive title) at the down. Please eliminate all extra spaces in the figures and between the parts of multipart figures. Photographs should be prepared in high resolution (at least 300 DPI) with tiff format and black and with.

Mathematical Expressions: All mathematical expressions should be included in the manuscript. Care should be taken to distinguish between capital and lowercase letters, between zero (0) and the letter (o), etc. Mathematical expressions should be centered and fit into a single column when set in type. Equations that might extend beyond the width of one column should be rephrased to go on two or more lines within column width. Numbers that identify mathematical expressions should be enclosed in parentheses. Refer to equations in text as "Eq. (1)," or "Equation (1)," etc., at the beginning of a sentence. Units: Authors should use the SI system of units.

Submission

- Submit the article through the journal website at jsst.ias.ir or the aerospace research website at https://www.ari.ac.ir/index.php/fa/journals-fa/space-sciences-and-technology-quarterly by registering in the electronic system of the journal.

Length:JSST manuscript length is based on the total number of words in the manuscript, including the abstract, equations, tables, and references. Extra allowance also must be made for figures, particularly when they are numerous. Regardless of its original length, your revised manuscript should be as short as you can reasonably make it while preserving clarity and essential content. Normal limits are as follows:

1. Full-Length Paper: approximately 6000-8000 words.
2. Technical or Engineering Note: approximately 2000 words.

Format and Style

1. General: The entire manuscript, including abstract, nomenclature, footnotes, references, figure captions and appendixes, must be 10-point type, Single, with 25 mm margins all around. Make the headings short but informative (specific), in boldface, centered, capitalized and numbered with Arabic numerals. Make sure that each sentence is clear and unambiguous, and that paragraphs are of reasonable length.
2. Title, Author's Name, Affiliation: The title should appear in uppercase letters and must be 18-point type in uppercase. A good title usually is six to eight words and is informative. The author's name should follow. Co­authors' names should be on the same line if they all have the same affiliation. If they have different affiliations, place each name on a separate line. Each affiliation line should contain the author's company or institution and city. The corresponding author's email and address should be provided.
3. Abstract: A Full-Length Paper must have an abstract of 300 (maximum) words. The abstract indicates the objec­tives of the investigation, the major techniques employed, and the outcome of the investigation at hand.
4. Keywords: The author should provide a set of keywords (5 to 7) which can be use to facilitate a search.
5. Nomenclature (optional): If symbols are used exten­sively you may insert their definition after the keywords. List the symbols in alphabetical order within each of the following groups: English group first, then Greek, subscripts, and superscripts. Numbers and other symbols should be listed last. Acronyms should be defined in the text, not in the nomenclature.
6. Introduction: The paper must include an introduction; a brief assessment of prior work by others and an expla­nation of how the paper contributes to the field.
7. Conflict of interest: Authors should clearly state any potential conflicts of interest, such as receiving money for research work, or gaining inventory or a stake in an organization that may be gained or lost through th publication of an article. Clearly stating the conflict of interest does not lead to the rejection of the article and we would like to be aware of it. If there is a conflict of interest should be explained and if there is no conflict of interest, the following sentence should be added to the end of the article, before appreciation and thanks. "No conflict of interest has been expressed by the authors."
8. Acknowledgments: All acknowledgments should ap­pear in a separate paragraph at the end of the manuscript, preceding the References.

References: 

-  Within the text, references should be cited in numerical order according to their order of appearance. The numbered citation should be enclosed in brackets.

- The format of the references and referencing in the text should be inserted using the IEEE method and using the EndNote software and link doi.

- All the references used in the article must be included in the list of articles in English.
