Now, they are also being used in space, for applications including real-time spacecraft navigation, timing, and scientific observations. In Low Earth Orbit (LEO), where most space users reside, GNSS signal reception is similar to that on Earth\u2019s surface. But, there is an increasing number of users in higher orbits as well, in what is known as the Space Service Volume (SSV).<\/p>\n\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.nasa.gov\/directorates\/somd\/space-communications-navigation-program\/the-interoperable-svv\/\" target=\"_self\" class=\"button-primary button-primary-sm link-external-true\">\n\t\t\t<span class=\"line-height-alt-1 \" >\n\t\t\t\tRead More                \t\t\t<\/span>\n\t\t\t<svg viewBox=\"0 0 32 32\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><circle class=\"button-primary-circle\" cx=\"16\" cy=\"16\" r=\"16\"><\/circle><path d=\"M8 16.956h12.604l-3.844 4.106 1.252 1.338L24 16l-5.988-6.4-1.252 1.338 3.844 4.106H8v1.912z\" class=\"color-spacesuit-white\"><\/path><\/svg>\n\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"grid-col desktop:padding-left-5\">\n\t\t\t\t\t\t\t\t<div class=\"display-block\">\n\t\t\t\t\t\t\t\t\t<div class=\"hds-tabbed-section-image margin-bottom-2 minh-mobile\">\n\t\t\t\t\t\t\t\t\t\t<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><img loading=\"lazy\" decoding=\"async\" width=\"985\" height=\"511\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?w=985\" class=\"attachment-large size-large\" alt=\"The Interoperable Self Service Volume\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png 985w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?resize=300,156 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?resize=768,398 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?resize=400,208 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?resize=600,311 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/ssv-graphic-web-03-03.png?resize=900,467 900w\" sizes=\"(max-width: 985px) 100vw, 985px\" \/><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The Interoperable Self Service Volume<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div>\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"hds-tabbed-section-tab desktop:display-flex \" data-tab-id=\"3\" role=\"tabpanel\" id=\"panel3-scan-program\" aria-labelledby=\"tab3-scan-program\" hidden>\n\t\t\t\t\t\t<div class=\"grid-col desktop:padding-right-5 padding-bottom-4 desktop:padding-bottom-0\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t\t\t\t\t<h2 class=\"heading-29\">Space Communications and Navigation (SCaN)<\/h2>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<p class=\"heading-16\">Exploration, enabled.<\/p>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<p class=\"p-md\">NASA\u2019s Space Communications and Navigation program, or SCaN,\u00a0serves as the program office for all of NASA\u2019s space communications activities.
