      Summary of Aiding Data Features for INS

      Posted by Will Dillingham on Aug 19, 2020 11:06:07 AM

      Last Updated: February 2020

      Purpose: To highlight the benefits and limitations of using aiding data for the Inertial Labs Inertial Navigation System (INS).
      The purpose of this article is to explain the benefits of using aiding data when operating an Inertial Labs Inertial Navigation System. For many applications, there is knowledge of position, orientation, or velocities that could be valuable during periods of GNSS outage. This additional information can be delivered to the Inertial Labs Kalman Filter and provide extended operation when other aiding data is not available. Unfortunately, the lack in understanding of how to use this data to benefit the user creates a lost opportunity for higher quality results, therefor this briefing will outline the benefits and overall types of data than can be of use for the Inertial Labs Kalman Filter.

      Measuring Linear Accelerations from External Monitoring Point

      Posted by Will Dillingham on Aug 19, 2020 10:19:42 AM

      Purpose: To instruct the user on what settings need to be configured such that one can monitor linear accelerations from an external monitoring point near, or around the INS.

      Note: This will also change the monitoring point for position, and velocity. Additionally, it is assumed that the monitoring point is rigidly attached to the same fixture where the INS is mounted.

      If offset is only a change in a few inches then the user may notice that the offset accounted for does not make a noticeable difference in sensor output.

      External Heading Input/Using Internal + External GNSS Simultaneously/Sending RCTM Corrections for INS

      Posted by Will Dillingham on Aug 18, 2020 1:31:48 PM

      Purpose: Answering common questions about applying external heading input; internal + external GNSS simultaneously; and sending RTCM corrections.

      Last Updated: July 2019

      Question: Does the INS support external heading input?
