The U.S. Army, for example, <a href=\"https:\/\/www.defensenews.com\/battlefield-tech\/2020\/09\/10\/army-launching-new-pnt-modernization-office-and-open-innovation-lab\/\" target=_blank>opened an office in September<\/a> to study the challenge, but the service has been <a href=\"https:\/\/www.c4isrnet.com\/intel-geoint\/2017\/10\/16\/the-army-is-developing-navigation-tech-to-help-the-gps-denied-soldier\/\" target=_blank>working on the issue for several years<\/a>. The Defense Department further stressed this need for positioning, navigation and timing solutions in 2019. The year before, BAE Systems said it was <a href=\"https:\/\/www.defensenews.com\/land\/2018\/01\/30\/bae-systems-to-develop-artillery-guidance-kits-that-work-in-gps-denied-environments\/\" target=_blank>developing ammunition<\/a> that can operate in GPS-denied environments.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/c4isrnet\/show-reporter\/ausa\/army-pnt\/2018\/02\/14\/no-gps-in-new-budget-request-that-could-be-less-of-a-problem\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/389260-P-SHK33-162.jpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">No GPS?

Video of how the system works shows a vehicle moving through a neighborhood. Instead of just seeing a house and balconies, the cameras see points on the balcony that correspond to a 3D model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Shmulik Olanski, who leads Rafael\u2019s land warfare innovation center and spent three decades in the Israel Defense Forces&#8217; Armored Corps, said the navigational challenge facing vehicles has to do with situational awareness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201c[The commander] needs to know where he is and what is around, and the commander in the command post needs to understand where the various forces are and do targeting procedures and lines of operation and to confront enemies in complex environments,\u201d Olanski told Defense News.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1889\" height=\"1218\" src=\"\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg\" alt=\"\" class=\"wp-image-62043\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg 1889w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg?resize=300,193 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg?resize=768,495 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg?resize=1024,660 1024w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/CT-MENTOR-2.JPG.jpg?resize=1536,990 1536w\" sizes=\"auto, (max-width: 1889px) 100vw, 1889px\" \/><figcaption class=\"wp-element-caption\">The interior view of the new CT-MENTOR system. (Rafael Advanced Defense Systems)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The algorithm provides locations to correct GPS in real time when the positioning system is jammed or down. That involves plotting \u201cthe number of houses, where friendly forces are [so] the commander knows where he is and this picture of what is going on [to] not just show him where he is on a map but also the position and all information \u2026 around him,\u201d Olanski said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIt allows us to <a href=\"https:\/\/www.c4isrnet.com\/battlefield-tech\/it-networks\/2019\/12\/13\/germany-hires-rafael-atos-to-create-a-glass-battlefield\/\" target=_blank>connect<\/a> this vehicle and armored vehicles to other sources on the same technology to make a common language and use the same infrastructure and technology, and allow them to understand common situational awareness and deliver information and targets to vehicles,\u201d he added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to Rafael project manager Bar O., whose last name cannot be used for security reasons, the system can operate even if there are changes to the environment, such as the destruction of buildings due to ongoing battle<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf there is 30-40 percent damage, the map still holds the 3D model and keeps itself very accurate without changing the model in your system,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the challenge of rapid, real-time updates to the system remains. Olanski said it could take hours for integrated tactical drones to create a 3D model, noting that closing the gap in time and accuracy is one of the company\u2019s goals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rafael says it designed CT-MENTOR with open architecture in mind so it can receive mapping materials from other systems, such as the <a href=\"https:\/\/www.defensenews.com\/digital-show-dailies\/ausa\/2020\/10\/14\/afghanistan-deployment-proves-one-world-terrain-is-more-than-a-training-tool\/\" target=_blank>American simulation tool One World Terrain<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Israeli system has been field tested, and the company is looking toward achieving operational capabilities. Rafael said the technology has been demonstrated for \u201cnumerous potential clients,\u201d but would would not say if the IDF is using it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because the system relies on cameras mounted on a vehicle, Rafael has built in protection and redundancy so it is hard for an enemy to destroy the whole system. Geared toward the urban environment, Bar said that this is the area with some of the most operational challenges when it comes to mapping and navigation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rafael\u2019s developers say CT MENTOR is most appropriate for advanced militaries. \u201cThe idea is, yes, it is at first for Western customers, but also aiming to adapt and upgrade vehicles of all types, and we are looking to add more technology onto this system as well,\u201d Bar said. \u201cThe key part is navigation. We have accuracy better than GPS and better than Waze, and [we have] situational awareness for a full sweep for commanders and crew, and common visual language for allied forces.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rafael Advanced Defense Systems has created a system that combines vehicle-mounted cameras with 3D models and mapping algorithms to help manned and unmanned vehicles operate in GPS-denied environments.<\/p>\n","protected":false},"author":7,"featured_media":62042,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":12,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[160,12,36],"tags":[],"coauthors":[3452],"class_list":["post-28454","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-daily-news-roundup","category-industry","category-newsletters"],"acf":{"subheadline":"","legacy_arc_id":"EQY7DD655JHQVNJOL2ZQPY4PWY","arc_canonical_url":"\/industry\/2020\/10\/16\/new-rafael-system-helps-vehicles-navigate-in-gps-denied-environments\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v26.0 (Yoast SEO v28.1) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>New Rafael system helps vehicles navigate in GPS-denied environments - Defense News<\/title>\n<meta name=\"description\" content=\"Rafael Advanced Defense Systems has created a system that combines vehicle-mounted cameras with 3D models and mapping algorithms to help manned and unmanned vehicles operate in GPS-denied environments.\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/one.sightlinemg.com\/c4isrnet\/industry\/2020\/10\/16\/new-rafael-system-helps-vehicles-navigate-in-gps-denied-environments\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"New Rafael system helps vehicles navigate in GPS-denied environments\" \/>\n<meta property=\"og:description\" content=\"Rafael Advanced Defense Systems has created a system that combines vehicle-mounted cameras with 3D models and mapping algorithms to help manned and unmanned vehicles operate in GPS-denied environments.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/one.sightlinemg.com\/defensenews\/industry\/2020\/10\/16\/new-rafael-system-helps-vehicles-navigate-in-gps-denied-environments\/\" \/>\n<meta property=\"og:site_name\" content=\"Defense News\" \/>\n<meta property=\"article:published_time\" content=\"2020-10-16T15:25:53+00:00\" \/>\n<meta property=\"article:modified_time\" content=\"2026-08-08T18:06:09+00:00\" \/>\n<meta name=\"author\" content=\"Seth J.
