Coast Autonomous equips its driverless shuttle with Ellipse-D

Our inertial sensor is part of our customer's 7-layer mapping and localization system for autonomous shuttle solution

Ellipse-D is a fully integrated INS/GNSS, very easy to implement in our solution

Our esteemed partner Coast Autonomous, is a company providing self-driving mobility solutions. From autonomous golf carts to utility vehicles. These solutions integrated our Ellipse-D inertial navigation sensor in their most recent P-1 driverless shuttle.

 

Driverless transportation solutions in urban environments

It is with the idea of “giving back the city to people” that Coast Autonomous invented the P-1 self-driving shuttle. This driverless shuttle has been designed to move people in pedestrian areas, such as urban environment or campuses. It can operate in mixed traffic as well as on high-speed lanes.

Three key features for the development of such a shuttle are safety, passenger experience, and appropriate speed, with the vehicle always analyzing its surroundings to determine its speed and behavior. Coast Autonomous technology ensures and safe and comfortable ride at varying speeds with smooth stop.

The solution has been successfully tested more than 60 times in seven countries, safely transporting more than 120,000 passengers. One of the trials took place in the crowded pedestrian area of Broadway in New York City, known as a “very difficult area for GNSS.”

 

Determine driverless shuttle location and direction

The company elaborated a fully-integrated 6-Level Autonomous System including robotics and artificial intelligence (AI), fleet management and supervision, as well as localization and mapping.

While a robotic software controls the shuttle, an artificial intelligence determines how the vehicle should behave and take decisions based on its environment.

As for mapping and localization, the company does not only rely on GPS/GNSS or beacons for navigation.

They built an entire system using 7 different technologies, such as inertial and SLAM.

This allows the shuttle to navigate indoors and even in harsh conditions such as near buildings or under canopies.

As these technologies are complementary, the system can determine the best one to use at a specific moment or in any environment.

The seven localization layers are:

• SBG Ellipse-D RTK GNSS/INS with dual antenna GNSS with speed sensor
• Odometry for dead reckoning
• 2D LiDAR SLAM
• 3D LiDAR SLAM
• Optical SLAM.

When RTK GNSS/INS becomes smaller & cheaper

The Ellipse-D was an Inertial Navigation System integrating a dual antenna and dual frequency RTK GNSS that was also compatible with our Post-Processing software Qinertia.

As the whole Ellipse Series product line has recently been renewed, this solution is now replaced by the Ellipse-D 3rd Generation.

This new INS/GNSS conserves all its previous features a smaller size and weight package and embeds a powerful 64bit architecture allowing high-end filtering.

Power consumption has also been reduced. Designed for automobile applications, it can fuse Odometer input with Pulse or CAN OBDII for enhanced dead-reckoning accuracy.
