The New Navigation System SOP To Replace GPS For Futuristic Autonomous Vehicles

Can you think of a world without GPS pushing its nose inside the high-end navigation system? The one and only technology with few derived attributes single-handedly serve the world. But what if a research group says they know a better alternative, will we prefer that? Let’s explore what we know about the newest path to tinker with the navigation concept. A research team from the University of California, Riverside has devised a prototype that requires no GPS to help serve navigation. Using cellular data or Wi-Fi only it can come up as a standalone system or else it could be coupled with the contemporary GPS technology to provide a reliable and tamper less surfing.

According to Zak Kassas, assistant professor of electrical and computer engineering at UCR's Bourns College of Engineering has reported that a couple of corresponding papers presented in the Institute of Navigation Global Navigation Satellite System Conference (ION GNSS+) have won the best paper presentation award. This specific project promises to appear as a viable navigation solution for the autonomous vehicles. Why is it required? Because the current system has multiple shortcomings which escalate when it comes to these autopilot devices.

GNSS – Global Navigation Satellite System is what currently connects the world comprising of four GPS pillars namely U.S. system GPS, Russian system GLONASS, European system Galileo, and Chinese system Beidou. If further refinement is required for defense related work, a short-lived aid named inertial navigation system is coupled to amplify the search. However no combination is full proof and will eventually turn up as an underequipped technology for next-gen autonomous vehicles.

The reasons are many but among them, the primary ones are extreme at its own goal. Firstly, if we consider the GPS signal alone it is way weak to counter high depth such as under-canyon places etc. Although it is dubbed as an all-weather support, jammers effect the signals plus it is an unencrypted an unauthenticated information that is hack-able. So, the systems appearing later in this era believe in multiplying sensors, applying sonar which is again a not-so-suitable idea for autonomous vehicles. And here comes their latest approach – Exploit what you have, just like AT&T’s large scale internet project AirGig.

The team under the leadership of Kassas in UCR's Autonomous Systems Perception, Intelligence, and Navigation (ASPIN) Laboratory has proposed to use the signal which is all around us, including cellular, radio, television, and WiFi. Naming them “Signals of Opportunity”, these could be used to drive the whole navigation system or could be used as a supplement to INS where GPS fails to reach. In the research project, theoretical analysis based upon the SOPs were jotted down with the software-defined radios (SDRs) that will capture timing and position, design algorithms and apply on futuristic vehicles. The complete research documented in two papers have now been uploaded in the UCR website.
