Hexagon’s Autonomy & Positioning and Mining divisions recently partnered with Mineral Resources Limited (MRL), a mining services company, to develop an automated road-train solution for deployment on MRL’s haulage fleet over the next two years. The solution integrates drive-by-wire technology with an autonomous management system to orchestrate vehicle movement in road-train haulage to improve safety, productivity and sustainability. We asked Lee Baldwin, the director of Hexagon’s Autonomy & Positioning division, a few questions about the system.
What does an automated road-train do?
It is for haulage on roads hundreds of kilometers long. It first will be used to move ore from a mine processing facility in the Pilbara region of Western Australia, about 1,200 kilometers north of Perth, to Port Hedland, where it is loaded on ships bound for Asia for use in steel mills. Typically, this is done using either rail or a road train, which is a highway truck pulling multiple trailers. Today, a person drives a road train.
What motivated this project?
Mines have difficulty finding drivers for mining trucks and road trains because the mines are very far away from the nearest city, Perth, so they must fly workers in and out, which is very costly. Many of them are on 10-day shifts. Also, there are safety concerns.
How does an automated road-train work?
It requires three typical subsystems that you would have on any autonomous vehicle. The first one is positioning, including redundant GNSS receivers with our TerraStar correction services. The second is a perception system for collision avoidance, using our HxGN MineProtect Collision Avoidance System. The third one is route planning. We will start by platooning, with a driver in the first truck, which will be followed by three unmanned ones, each towing multiple trailers. Each truck will have the positioning, perception and route-planning systems. Later, we will achieve full autonomy by removing the driver from the lead vehicle.
How will the transfer at the mine work?
At a mine site, the road train will be commissioned in a sequestered area, then sent to a loading area where it will be loaded with ore, either automatically or by a manned wheel loader. Next, it will travel 200 kilometers to the port, where it will dump the ore. Finally, it will be decommissioned and queued up for the return journey.
Which parts are already in place and which ones are still being developed?
At Hexagon, we are already putting technology in manned mines. For example, we already have the collision-avoidance system, a fleet management system, and some sitewide planning systems. However, the trucks that the customers are choosing will have to be converted to be drive-by-wire to accommodate our autonomy system. They will use two PwrPak7 GNSS receivers and the TerraStar correction service.
Farmers rely on their GNSS receivers to keep their machines on track, their maps accurate, and their rows straight in demanding environments. GNSS receivers on agricultural equipment need to continue to perform at a high level when faced with extreme weather, temperature and vibration while navigating varying terrain. In addition, farmers rely on the correction services that provide them with the high accuracy needed to keep them operating. Still, they face challenges with outages and interruptions from obstacles blocking satellite signals.
Hexagon | NovAtel’s SMART7 GNSS receiver and TerraStar Correction Services together create an accurate, robust and reliable solution for farmers. These products undergo extensive testing to ensure a high-performing and dependable solution. The SMART7 accesses all four GNSS constellations (GPS, GLONASS, BeiDou and Galileo), providing the best availability in variable terrain and environmental conditions. To compensate for the pitch and roll in the field, the receiver includes terrain compensation — keeping farmers at centimeter-level accuracy when using TerraStar-C PRO, TerraStar-X or RTK corrections.

TerraStar Correction Services are based on a global network of advanced and proprietary GNSS control centers to ensure 99.999% signal availability to farmers. By delivering quality satellite corrections without the need for base stations, farmers can get the accuracy needed for their operations in a scalable format that moves with their equipment.
Jacob Van Den Borne is a potato farmer in the southern region of the Netherlands. He has been working with precision farming for more than 10 years and recently switched his Fendt tractor to NovAtel’s SMART7. Throughout his last season, Jacob noticed a substantial improvement in signal reception while passing along the edges of his heavily treed field. Previously, his GNSS equipment would lose reception, causing his rows to wander. After using a SMART7 for one season and experiencing its high precision and reliability, Van Den Borne plans to switch all receivers on his farm to the SMART7.
Evolving advanced driver-assistance systems (ADAS) and developing safe perception and positioning systems in the agriculture industry are top priorities for NovAtel. With the challenges faced by farmers, finding new ways to support a sustainable increase in their production and productivity will help ease the pressures of a growing population.
Hexagon’s Autonomy and Positioning division has launched its first autonomy positioning and sensing kits for the agriculture market and validated these solutions in its new autonomous research and development tractor.
Through collaboration between NovAtel and AutonomouStuff, both part of Hexagon, the autonomous positioning and sensing kits were developed as part of Hexagon’s Smart Autonomous Mobility solutions portfolio launched at CES in early 2020. NovAtel and AutonomouStuff created the solutions with agriculture machinery OEMs and robotic machinery manufacturers in mind.
As a demonstrator vehicle for Smart Autonomous Mobility, the autonomous tractor features object detection and classification, simultaneous relative localization and mapping, absolute positioning through GNSS technology, and localization sensor fusing. Built to illustrate the viability of new positioning and sensing kits, the tractor incorporates safety-critical learnings with situational and environmental awareness, and manual remote control when needed. This platform validates how these solutions and capabilities accelerate autonomous development.

The positioning and sensing kits are optimized for autonomous agriculture applications, including products like the Smart7 antenna and autonomous robotic capabilities through the NovAtel OEM7 driver powered by the Robot Operating System (ROS). The kits also feature TerraStar GNSS Correction Services, ALIGN heading and relative positioning firmware, and SPAN GNSS+INS technology. Though designed for agriculture, the kits integrate seamlessly into other off-road autonomy applications.
“These positioning and sensing kits provide developers with technology bringing assured positioning to autonomy in agriculture,” explained Michael Martinez, agriculture segment manager at Hexagon | NovAtel. “Robotic-machinery manufacturers or those experienced in autonomy may be unfamiliar with the unique challenges facing agriculture applications. Conversely, those experienced with agriculture may not have the expertise to integrate positioning and sensing products within autonomous solutions. We can help in both cases through these positioning and sensor kits, as demonstrated by our autonomous tractor.”

“We’re excited to use this tractor as a platform to validate the human identification, obstacle detection and enhanced environmental awareness that our sensing kits add to our assured positioning solutions in agriculture,” said John Buszek, VP of products and services at Hexagon | AutonomouStuff. “The sensing and positioning technologies we’ve integrated on this demonstration platform showcase the Smart Autonomous Mobility portfolio, which enables and accelerates the development of autonomy in agriculture applications from prototyping to production.”
For more than 30 years, NovAtel has delivered GNSS positioning solutions as a trusted provider for top precision agriculture companies. Combined with AutonomouStuff’s decade of expertise in autonomy and sensor fusion, they significantly reduce the barrier of entry into autonomy to accelerate the time to market for autonomous solutions in agriculture, construction, mining and other off-road applications.
