Restricting customers to service within one network led to high prices for out-of-network calls and limited value for customers. Cellphone providers long ago adopted roaming, allowing devices to jump from network to network without interrupting service and increasing competition across the industry and value to consumers.<\/p>\n\n\n\n<p>Roaming isn\u2019t available in space, so network access is an issue as satellites and spacecraft orbit the Earth. This will soon change as NASA develops a new Wideband Ka-band communications terminal, which is a transceiver that operates over government and commercial Ka-band spectrum allocations (17.7 GHz \u2013 31 GHz). This roaming function will give spacecraft the ability to seamlessly connect to various communications networks and allow for multi-access points of services, lower latency, and lower costs.<\/p>\n\n\n\n<p>\u201cThis is a first for a Ka-band user terminal,\u201d said Nang Pham, Wideband Project Manager at NASA\u2019s Glenn Research Center in Cleveland. \u201cThe versatile capabilities demonstrated by the terminal bring us a step closer to space communications interoperability for future NASA near-Earth missions.\u201d<\/p>\n\n\n\n<p>The new terminal will support NASA\u2019s plans to rely exclusively on <a href=\"https:\/\/www.nasa.gov\/directorates\/heo\/scan\/services\/nasas_commercial_communications_services\">commercial providers<\/a> for near-Earth space communications and navigation operations by the mid-2030s and further foster an affordable and robust space commercialization path in the United States.<\/p>\n\n\n\n<p>For almost 40 years, NASA has relied on its <a href=\"https:\/\/www.nasa.gov\/mission_pages\/tdrs\/home\/index.html\">Tracking and Data Relay Satellites<\/a> (TDRS) system to provide near-constant communication links between the ground and satellites in low-Earth orbit, but the infrastructure was not originally designed for interoperability between networks.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png\"><img loading=\"lazy\" decoding=\"async\" width=\"879\" height=\"703\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png?w=879\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Large satellite dishes positioned on a rooftop and pointed toward a blue sky.\" 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\/2021\/06\/wideband_002.png 879w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png?resize=300,240 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png?resize=768,614 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png?resize=400,320 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2021\/06\/wideband_002.png?resize=600,480 600w\" sizes=\"(max-width: 879px) 100vw, 879px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The Wideband Ka Terminal Antenna assembled at NASA\u2019s Glenn Research Center conducts an over-the-air demonstration of roaming capabilities.<\/div><div class=\"hds-credits\">Credits: NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>This new Wideband Ka terminal prototype will allow satellites to connect with multiple space relay networks, including TDRS, enabling NASA\u2019s transition from government to commercial space communications services.<br>\u201cThis terminal will allow missions to reduce risk and costs by offering competitive choices for where they get their commercial satellite service,\u201d said Marie Piasecki, Wideband Project Principal Investigator at Glenn. \u201cA high Technology Readiness Level terminal capable of operating on a wide assortment of networks truly takes advantage of commercial investments in space.\u201d<\/p>\n\n\n\n<p>NASA recently concluded a month of trailblazing tests that successfully demonstrated communications over-the-air with the Wideband Ka terminal prototype for the very first time. A groundbreaking roaming experiment was the highlight of testing, where services switched in real-time between NASA\u2019s TDRS system and Inmarsat\u2019s Global Xpress Satellite.<\/p>\n\n\n\n<p>This successful demonstration provides proof of initial roaming capabilities and confidence that commercial services can one day support future space users. The Wideband Ka terminal prototype is at a sufficiently high technology readiness level that the next technology transitional phase will be to demonstrate in a space environment.<\/p>\n\n\n\n<p>The Wideband terminal prototype will now undergo additional ground testing and demonstrations with various commercial service providers. NASA\u2019s <a href=\"https:\/\/www1.grc.nasa.gov\/space\/scan\/\" rel=\"noopener\">Space Communications and Navigation program<\/a> is planning a flight demonstration, currently targeted for 2025, to evaluate in-orbit roaming capabilities across multiple government and commercial networks.<\/p>\n\n\n\n<p><strong><em>Molly Kearns<\/em><\/strong><br><strong><em>NASA\u2019s Glenn Research Center<\/em><\/strong><\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-full width-full maxw-full padding-x-3 padding-y-0 hds-module hds-module-full wp-block-nasa-blocks-related-articles\">\t\t<section class=\"hds-related-articles padding-x-0 padding-y-3 desktop:padding-top-7 desktop:padding-bottom-9\">\n\t\t\t<div class=\"w-100 grid-row grid-container maxw-widescreen padding-0 text-align-left\">\n\t\t\t\t<div class=\"margin-bottom-4\"><h2 style=\"max-width: 100%;\" class=\"width-full w-full maxw-full\">Explore More<\/h2><\/div>\n\t\t\t<\/div>\n\t\t\t<div class=\"grid-row grid-container maxw-widescreen padding-0\">\n\t\t\t\t\t\t\t\t\t\t<div class=\"grid-col-12 desktop:grid-col-4 margin-bottom-4 desktop:margin-bottom-0 desktop:padding-right-3\">\n\t\t\t\t\t\t<a href=\"https:\/\/www.nasa.gov\/centers-and-facilities\/johnson\/lakita-lowe-leading-space-commercialization-innovations-and-fostering-stem-engagement\/\" class=\"color-carbon-black\">\n\t\t\t\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t\t\t\t<div class=\"hds-cover-wrapper cover-hover-zoom bg-carbon-black minh-mobile\">\n\t\t\t\t\t\t\t\t<figure class=\"hds-media-background  \"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/06\/lakita-issrdc-2022.jpg?w=300\" class=\"attachment-medium size-medium\" alt=\"\" style=\"transform: scale(1);
