The robot remained stationary while GPS position data was collected and converted into local Cartesian coordinates. This test evaluates localization repeatability and sensor jitter, rather than absolute global position accuracy.<\/p>\n\n\n\n As shown in the table below, the GNSS-RTK module produced highly stable position estimates. The total 2D position stayed within 0.73 cm of the average position, and the RMS variation was 0.28 cm. These results show that the localization subsystem provides stable input for autonomous navigation and planting location estimation.<\/p>\n\n\n\n GPS Localization Static Open-Sky Unit-Test Results<\/p>\n\n\n\n| Metric<\/td> | X (cm)<\/td> | Y (cm)<\/td> | Total 2D (cm)<\/td><\/tr> | | Max horizontal drift<\/td> | 0.63<\/td> | 0.56 <\/td> | 0.73<\/td><\/tr> | | Total position range<\/td> | 1.25<\/td> | 1.10 <\/td> | 1.66<\/td><\/tr> | | RMS variation<\/td> | 0.23 <\/td> | 0.16<\/td> | 0.28<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n The low drift and RMS variation indicate that the GNSS-RTK subsystem is stable enough to support the project requirement of identifying planting locations within 1 m precision.<\/p>\n\n\n\n Design Brainstorming<\/h2>\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":" Running Slides \u2013 our Progress MRSD Capstone \u2014 Running Slides Reports Presentations Progress Reviews \u2013 Spring Semester Progress Reviews \u2013 Fall Semester Individual Lab Reports (ILR) ILR\\Team Member Alina Wang Neha Kayiti Istan Slamet Sean Min Shuyi Lin ILR01 ILR01 […]<\/p>\n","protected":false},"author":476,"featured_media":0,"parent":0,"menu_order":3,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-11","page","type-page","status-publish","hentry","clearfix"],"_links":{"self":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/pages\/11","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/users\/476"}],"replies":[{"embeddable":true,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/comments?post=11"}],"version-history":[{"count":31,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/pages\/11\/revisions"}],"predecessor-version":[{"id":497,"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/pages\/11\/revisions\/497"}],"wp:attachment":[{"href":"https:\/\/mrsdprojects.ri.cmu.edu\/2026teamj\/wp-json\/wp\/v2\/media?parent=11"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}} |
