Currently, satellite navigation chips mainly include components such as GNSS RF receivers, GNSS baseband signal processors, microprocessors, power management, memory and control units, storage devices, serial devices, and peripheral interface circuits. Due to the complexity of chip design, especially the integration of RF and baseband in SoC chips, the ability to design satellite navigation chips directly impacts their performance, sensitivity, power consumption, size, and cost. This, in turn, greatly affects the competitiveness of navigation and positioning terminal products. Therefore, the direction of development for satellite navigation chips largely represents the trends of satellite navigation terminal products. From the structure of satellite navigation chips, it is clear that integration, performance, and […]<\/p>\n","protected":false},"author":1,"featured_media":1471,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[36],"class_list":["post-1470","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-insights","category-blog","tag-yvette-wu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1470","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/comments?post=1470"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1470\/revisions"}],"predecessor-version":[{"id":1472,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/posts\/1470\/revisions\/1472"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/media\/1471"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/media?parent=1470"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/categories?post=1470"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ja\/wp-json\/wp\/v2\/tags?post=1470"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
