I.D.# C1026Printable Description
Duration: 1 Day

This seminar addresses vehicle positioning and navigation systems. The first part of the seminar provides an overview of the Global Positioning System (GPS) since it is the main location technology enabler for automotive location-based applications. The following topics will be discussed: coordinate reference frames, satellite constellation, signal structure, ranging observables, ranging error sources, error mitigation techniques, position velocity and timing (PVT), accuracy and availability for different modes of positioning that include open-loop, differential GPS (DGPS), real-time kinematic GPS (RTK), GPS dead-reckoning, augmentation of GPS with wheel speed sensors, inertial measurement units and compasses. Sensor fusion using a Kalman filtering technique will be included. GPS accuracy and availability performance in automotive driving environments, GPS vehicle installations (antenna, RF cable and GPS receiver), and bench-level and vehicle-level methods to evaluate GPS will be covered. An introduction to automotive navigation systems will be presented. Topics such as map database sources, route guidance calculations, and graphical user interfaces will be covered.

Learning Objectives
By attending this seminar, you will be able to:

  • Specify the performance of GPS receivers and navigation systems
  • Evaluate the performance of GPS receivers and navigation systems
  • Integrate the GPS with other sensors via a Kalman filter to improve navigation availability
  • Select the appropriate implementation of a vehicle navigation system based on your application requirements

Who Should Attend

This course is appropriate for engineers or managers who want a better understanding of the technologies involved in vehicle to vehicle and vehicle to infrastructure applications. Those interested in wireless communications application to vehicular environments, vehicle positioning systems used for connected vehicles, vehicular software architectures and security, and vehicle system applications such as active safety as they apply to automotive/commercial vehicles will find this course useful.

Other professionals who will benefit from this course include: managers seeking to evaluate technology/ regulation/standardization/business trends; fleet operators looking to increase business productivity, better manage their assets, meet regulatory requirements more efficiently, and improve asset utilization; business stakeholders involved in controlling/exploiting data transmitted from/to vehicles; those involved with autonomous/unmanned vehicles; and professionals interested in the perspective that the mobility, data security, and safety aspects of connected vehicle systems can enhance the reliability and control of driver-assisted vehicles.
