enable the Gaussian Noise overlay function according to the test requirements after setting up the constellation frequency point. Gaussian White Noise (AWGN) is often considered as the baseline configuration for simulating the real electromagnetic environment in GNSS radio frequency simulation tests. However, engineering practice has shown that the effect of noise on receiver performance is not linearly monotonic.<\/p><p data-start=\"379\" data-end=\"458\">Regarding the practical application of this feature and its impact on positioning results, we have received feedback and questions from some users: \"Why is the positioning more stable with noise enabled? \"Why does enabling noise cause star loss in weak signal environment?<\/p><p data-start=\"460\" data-end=\"492\">Therefore, this paper will deeply analyze the logic of Gaussian noise in GNSS simulation.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5d10f90 elementor-widget elementor-widget-image\" data-id=\"5d10f90\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"646\" src=\"https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-1024x646.webp\" class=\"attachment-large size-large wp-image-34193\" alt=\"\" srcset=\"https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-1024x646.webp 1024w, https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-300x189.webp 300w, https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-768x484.webp 768w, https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-18x12.webp 18w, https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9-600x378.webp 600w, https:\/\/aiportek.com\/wp-content\/uploads\/2026\/03\/640-9.webp 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1fd6f8f elementor-widget elementor-widget-heading\" data-id=\"1fd6f8f\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Physical Definition and Necessity of Gaussian Noise in GNSS Simulation<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a046c3e elementor-widget elementor-widget-text-editor\" data-id=\"a046c3e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"529\" data-end=\"618\">In an ideal mathematical model, satellite signals are perfectly tuned to the BPSK sequence at a specific frequency; however, in real physical environments, signals are inevitably overlaid with thermal noise.

By adding AWGN, the simulator can precisely control the carrier-to-noise ratio (C\/N0), creating a bridge between \"digital simulation\" and \"RF physics\".<\/li><li data-section-id=\"r12ece\" data-start=\"741\" data-end=\"882\"><strong data-start=\"744\" data-end=\"774\">Receiver Algorithm Stress Test (The Stress Test)<\/strong>The core capability of a GNSS receiver is to extract valid signals from noise.
