Course 512 Details

 

Course 512: Ultra-Tight, Deep Integration of GPS/INS (0.5 CEUs) On-Site Only
Instructors: Dr. James Sennott, Tracking and Imaging Systems, Inc. (TISI)

Description

Using a waveform estimation-theoretic approach, this half-day course develops architectures approaching theoretical limits, given the GPS signal-in-space. Building upon Kalman prerequisites the fundamental observation and dynamical models are described, leading to practical integrations. Augmentations are described for high dynamics, signal blockages, and jamming. Modeling and simulation approaches critical to the design and evaluation process are emphasized followed by case studies.

Objectives

This half-day course is designed to help the attendee better understand how to develop, integrate and evaluate advanced GPS-IMU integration systems involving ultra tightly coupled architectures.

Prerequisites

Kalman filtering background from Courses 447 or 537 (Day 1 and Day 2), or equivalent experience. GPS background as covered in Course 356, or equivalent experience. Inertial background as covered in Courses 447 or 537 (Day 1 and Day 2), or equivalent experience.

Who Should Attend?
