Geoffrey,

There are a number of companies that offer real-time location systems that might work for your needs. These include:

Airfinder
AB&R
Convergence Systems Ltd.
Extronics
Litum
Zebra Technologies

In general, UWB systems will provide greater location accuracy.

IdentPro, a German company, offers a RTLS for lift trucks that uses 2D-LIDAR sensors mounted on the vehicles. The lift trucks determine their position by detecting the contour of the surrounding. The system works indoors and out with no break.

Geoffrey, There are a number of possible solutions that cover a range of accuracy, response time, human interaction and price. In your case, answering questions like the size of the yard and how often things move could drastically change the scope of an implementation. This could be a quick and simple implementation or a system that can be expanded to fit more complex business requirements. A good suggestion would be to talk with an integrator that can help guide you with the overall solution. InformaTrac offers free consultation for these types of projects and can help to answer all your questions and point you in the right direction. Kris Hughes InformaTrac, Inc (www.InformaTrac.com)

Geoffrey, If you are looking for the best accuracy with the minimum of interference and maximum range then a UWB, Ultra-Wideband system is most appropriate. Deploying an RTLS solutions is an investment and therefore it is important to look at your current needs as well as investigating how you can expand the system in the future to cover more of your use cases. Today you need to track forklifts in an open yard, but the solution you choose should be able to expand into other use cases such as tracking within your facility for location of any asset including objects (such as goods/parts on pallets or bins) and people. A system that allows for physical tag tracking as well as virtual pinning with multiple technologies will offer the most cost effective solution. I agree that discussing your current and future needs with both integrators and system solution vendors is key and the place to start. Position Imaging is available to discuss your needs and see which approach may best serve your needs today and in the future. Liisa Walsh, Lead Product Manger Position Imaging, Inc.

We can offer a Active RF based solution. Need more information about size, number of objects to be tracked. Plz drop mail to rajendra@ecartes.in www.ecartes.in

Seeonic offers an active tracking solution that will work on forklifts without any infrastructure required for power or communications. Our solution called XTAG contains communications and power all embedded with the XTAG. The location accuracy would depend on the specific application.

Geoffrey, If you are interested to build your own solutions swarm bee technology from is best suited. It combines autonomous zoning for V2V and V2P applications with real-time position tracking. Have a look here: https://nanotron.com/EN/collision-avoidance/ If this is what you are looking for give us a shout. Thomas Foerste

Hi Geoffrey, WISER Systems has worked quite a bit in this space. We've developed a UWB system to track critical assets like forklifts with high precision in real time. You can take a look at how this works with forklifts: https://www.wisersystems.com/forklift-tracking Finding the right solution can be a lot of work, so I wish you the very best with the process! -Stephen

Hi Geoffrey, Certainly as you can observer from the above there are many options to track a forklift. Having lived RTLS for close to 20 years with companies like WhereNet - Zebra - Mojix and having worked with various RTLS technologies 2.4GHz Active based, UWB, passive RFID based - it always comes down to the main question what problems are you exactly trying to solve and what are the current consequences / cost of not doing anything. Certain is there are a range of solutions that will work for you - the biggest question to answer is what is a fair cost to solve your problem and is there a solution of which the total cost of ownership fits in that budget. The company I currently work at is not actively selling RTLS solutions but feel free to reach out to me - happy to share my experiences and lessons learned from the past many years. Wishing you the very best in your search journey. Egon

https://www.rfidjournal.com/articles/view?18212 I suggest the following article to give you some ideas. A moving vehicle with mounted RFID reader and GPS will used to track locastions of containers in a large shipyard. Using GPS this can be adapted to any area size and purpose. Such a system on wharehouse forklift trucks could also be used to constantly update inventory and location in a storage area even while doing other work. If such a system also had a way to determine the direction and distance to the passive tag the location of the tag could be resolved. I submit a fairly accurate solution can be obtaind using the GPS by observing signal strenths/delay over time of each tag while traveling in a known direction at a known speed. This can identify at least the point of nearest approch and its signal strength/delay. Over time the same tag will be pickup up many times from different locations within the storage area and comparison with those points of nearest approach signal strength/delay should make this solution straight forward. Even the rate at which the signal strengthg/delay changes at different velocities of GPS motion should give you an close apprioximation of the distance normal to the track's direction of travel where the tag is located. That resolves to two possible locations on the first pass. Retravel, even in the same traffic pathway would have to follow exactly the same direction of travel (or its 180 degree complement) for you not to be able to refine that location.
