2021/03/09 NavtechGPS is offering the following multi-day training sessions on GNSS/GPS technology in New Orleans this December. Both courses will take place at the InterContinental New Orleans Hotel. Photo: InterContinental New Orleans Hotel Dec. 9-12 (4 days) Course 346: GPS/GNSS Operations for Engineers and Technical Professionals Instructor: Dr. Chris Hegarty, MITRE Take this 4-day course to gain a comprehensive understanding of GPS/GNSS system concepts, design and operation, including information on GPS signal processing by the receiver; techniques by which GPS obtains position, velocity and time and a brief introduction to differential GPS (DGPS) and Kalman filtering. Dec. 9-13 (5 days) Course 557: Inertial Systems, Kalman Filtering and GPS/INS Integration Instructors: Dr. Alan Pue, Johns Hopkins, APL; Mr. Michael Vaujin, Aerospace, Navigation & Defense Consultant. Expanded to a full five full days based on attendee requests, this course on GPS-aided navigation will thoroughly immerse you in the fundamental concepts and practical implementations of the various types of Kalman filters that optimally fuse GPS receiver measurements with a strapdown inertial navigation solution. The course includes the fundamentals of inertial navigation, inertial instrument technologies, technology surveys and trends, integration architectures, practical Kalman filter design techniques, case studies, and illustrative demonstrations using MATLAB. Five fulls days allow for a fuller and detailed development of the design of an aided navigation system, combined with a detailed discussion of the use of lower quality IMUs, and advanced filtering techniques.
