Many test environments expose inertial systems to extreme dynamics, abrupt shocks, or sudden standstill events. The inertial system needs to get along with these harsh conditions and to keep its initialization data to save plenty of time. A critical factor behind this performance is the ability to maintain <strong>Kalman filter stability<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-advanced-standstill-detection-asd-the-key-to-stability\">Advanced Standstill Detection (ASD): The Key to Stability<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:50%\">\n<p>Our <strong>Advanced Standstill Detection<\/strong> technology ensures that ADMA remains stable even when other systems fail. ASD prevents kalman filter \u201ccrashes\u201d during abrupt dynamics or vehicle collisions because of misinterpretation of sensor data. It keeps Heading, Position and velocity stable which enables the kalman filter to provide consistent measurement data. This exclusive ASD technology gives the ADMA a level of stability and performance that remains unrivaled across the industry. It delivers full standstill detection without relying on odometry, external velocity sources, or dual\u2011antenna setups &#8211; everything is handled seamlessly through single\u2011antenna GNSS and intelligent sensor fusion.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"788\" height=\"1024\" src=\"https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-788x1024.jpg\" alt=\"Shows a vehicle crash with a target platform and ADMI, who is pretty happy, that doesn't need to restart the intertial system, but just hit &quot;new measurement&quot;.\" class=\"wp-image-46579\" srcset=\"https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-788x1024.jpg 788w, https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-231x300.jpg 231w, https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-768x998.jpg 768w, https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-300x390.jpg 300w, https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1-696x905.jpg 696w, https:\/\/genesys-offenburg.de\/wp-content\/uploads\/2026\/02\/Target-Crash_Vertikal_v1.1.jpg 800w\" sizes=\"(max-width: 788px) 100vw, 788px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p>A common example is found in ADAS test scenarios, where the <a href=\"https:\/\/youtu.be\/ME7u8XYp0Bs?si=aMlvblRIOBsyFeb3&amp;t=4\">hunter vehicle may accidentally collide with a target platform<\/a>. In such events, the physical impact exceeds the maximum thresholds of the IMU and GNSS sensors. <\/p>\n\n\n\n<p>Without additional logic, this would cause the Kalman filter to diverge due to the sudden surge of false acceleration, angular\u2011rate, or Doppler values with the need of a re-initialization of the inertial system. With ASD and additional protective algorithms, ADMA can reliably detect these crash events, identify the exceeded thresholds, and suppress corrupted sensor data during the impact phase. This prevents the filter from integrating invalid values and ensures that heading, position, and velocity remain stable, even when the platform or vehicle experiences an unexpected collision.<\/p>\n\n\n\n<p>ASD combines:<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<ul class=\"wp-block-list\">\n<li><strong>IMU indicators<\/strong> (accelerometer and gyroscope patterns)<\/li>\n\n\n\n<li><strong>GNSS Position information<\/strong> (When RTK available)<\/li>\n<\/ul>\n\n\n\n<p>This multi-channel approach allows ADMA to confidently detect standstill and keep the kalman filter stable.
