Amazon has also announced it will move ahead with its own Project Kuiper broadband network of 3,200 satellites, starting the launch phase in early 2024. These networks, by design, cover the entire globe, meaning no area on Earth would be free from their interference. <\/p>\n\n<p class=\"article-full-body sans-serif\">To remedy this, the paper proposes creating special zones which have the same protections&nbsp;<span>from outside radio transmissions as quiet zones, but would be outfitted with monitors. Astronomers, satellite manufacturers and other technology developers could then use the areas to test their receivers and transmitters at large scales, ensuring they do not unknowingly encroach on astronomical observations. <\/span><a href=\"http:\/\/cps.iau.org\">cps.iau.org<\/a><\/p>\n\n<p class=\"footer\">PHOTO: ZHENGZAISHURU<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Special radio transmission zones could protect astronomical observations<\/p>\n","protected":false},"author":24,"featured_media":44054,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ub_ctt_via":"","purple_page_number":"13","purple_custom_meta_purple_page_number":"13","purple_seq_number":"2","purple_custom_meta_purple_seq_number":"2","purple_source_article":"article_13-2.xml","purple_custom_meta_purple_source_article":"article_13-2.xml","purple_source_issue":"May-2023","purple_custom_meta_purple_source_issue":"May-2023","purple_external_id":"May-2023-13-2","purple_custom_meta_purple_external_id":"May-2023-13-2","purple_issue_code":"|0000086564||","purple_custom_meta_purple_issue_code":"|0000086564||","purple_android_product":"com.im.skyatnight.216","purple_custom_meta_purple_android_product":"com.im.skyatnight.216","purple_ios_product":"com.im.skyatnight.216","purple_custom_meta_purple_ios_product":"com.im.skyatnight.216","purple_web_product":"","purple_custom_meta_purple_web_product":"","purple_publication_id":"075fab74-0a21-4201-866a-899d6c41c40c","purple_migrated":"","kt_blocks_editor_width":""},"categories":[19],"tags":[14],"featured_image_src":"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview.jpg","author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"acf":{"readingTimeMinutes":"2","apple_news_title":""},"uagb_featured_image_src":{"full":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview.jpg",1600,1066,false],"thumbnail":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview-150x150.jpg",150,150,true],"medium":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview-300x200.jpg",300,200,true],"medium_large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview-768x512.jpg",768,512,true],"large":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview-1024x682.jpg",800,533,true],"1536x1536":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview-1536x1023.jpg",1536,1023,true],"2048x2048":["https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/04\/GettyImages_1156913981_preview.jpg",1600,1066,false]},"uagb_author_info":{"display_name":"importmanagerhub@sprylab.com","author_link":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/author\/importmanagerhubsprylab-com\/"},"uagb_comment_info":0,"uagb_excerpt":"Special radio transmission zones could protect astronomical observations","_links":{"self":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/43632"}],"collection":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/users\/24"}],"replies":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/comments?post=43632"}],"version-history":[{"count":4,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/43632\/revisions"}],"predecessor-version":[{"id":44279,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/posts\/43632\/revisions\/44279"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media\/44054"}],"wp:attachment":[{"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/media?parent=43632"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/categories?post=43632"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/c01.purpledshub.com\/bbcskyatnight\/wp-json\/wp\/v2\/tags?post=43632"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
