If surveying isn’t your main day to day activity but you still have a need for cm positions in your workflow, then the business case for Trimble’s Catalyst is a strong one.

Trimble Catalyst is a revolutionary, GNSS concept delivering positioning as a service to mobile devices. It turns your existing Android or iOS device into a precision mapping, navigation and measurement tool that you can use with any location enabled app or service including KOREC Capture and Esri FieldMaps.

The cost of the Catalyst hardware has been kept low at just £300 per receiver and subscriptions come in a range of choices depending on the number of licenses required and hours used.

However, Trimble Catalyst is not a solution for those who cite survey grade accuracy as the primary part of their working day. Instead, Catalyst has been developed for users who require cm positions as back up to the bulk of their work, for example, the scientist who needs to know precisely where a sample was collected, the utilities engineer who needs to position a valve or the knotweed removal specialist who must know exactly where the plant is located.

In short, the best way to assess whether Trimble Catalyst will provide the best value proposition for your cm positions is to base it on the number of points you typically over the period of a year.

Case study: DTM Technologies

Typical of the type of user who can benefit from the enormous savings Catalyst delivers is Owner/Director of DTM Technologies, Alan Roberts.

Established in 2014, North Wales based DTM Technologies offers a range of specialist 3D Structural and 3D Modelling Services capturing data predominantly through 3D Laser Scanning and drones. The company uses the very latest in data capture technology (Including the Trimble TX8 Laser Scanner) and provides the high resolution and accurate survey, mapping and environmental information that’s often used to form the basis of any construction (BIM), environmental or engineering project.

With the majority of Alan’s work requiring either a point cloud or aerial imagery, he has an important but fairly minimal need for cm positions. Six years ago, his approach was to purchase a survey grade GNSS system and a license for the corresponding annual correction service. However, he is quick to cite that he is not an engineer or a degree trained surveyor and during the years with this system, he found it expensive to use. As well as the up-front costs for the initial purchase of the hardware, he was also paying an annual correction service charge of around £1,200 p.a. – both large outlays. He therefore sought a solution that would better fit his requirements, spread the cost and offer better value overall.

Alan accordingly purchased a Trimble Catalyst receiver from KOREC and selected the subscription service best suited to his workflow from the options of 60 cm, 30 cm, 10 cm or 1 cm, in this case 1cm. The Catalyst antenna was compatible with his existing mobile phone, easy to set up and required no specialist positioning or GNSS knowledge for use.

The Business case in numbers

Alan states that in a standard working month he may carry out around four surveys that require cm positions and that he can capture the four or five points he requires plus a few check points in one hour of subscription time. He is therefore spending just £10 per site for cm positions, around four times a month. Based on those figures, with the subscription cost spread over a 12 month period, his annual running costs are £480.

Upfront hardware savings ≈ £9600

Annual running cost savings ≈ £760 p.a.

As an experienced user of Trimble Catalyst, even Alan still believes that that system is almost too good to be true. “With Trimble Catalyst, achieving cm accuracy in the field is no longer a niche occupied only by land surveyors, often with the price tag to match. Previously, I was pretty well priced out of the market for this level of accuracy but Catalyst really does bring high cm positions to a mass audience. I’m now in a good position to pass my savings on to my clients which definitely helps in a competitive marketplace.”

Next steps – the new Catalyst DA2

Alan was an early adopter of the Trimble Catalyst system and is already assessing the recently released DA2 receiver.

With much of his work in Snowdonia, mobile phone reception is often compromised and even taking three different SIM cards doesn’t always guarantee a successful connection. The DA2 comes with RTX corrections which means he will no longer be reliant on receiving his cm corrections over an internet connection. Thanks to Trimble’s RTX technology he will be able to get his corrections via satellite.

In addition, the DA2’s ProPoint technology will enable him to pick up his positions in challenging GPS conditions such as near tree canopy.

We’d like to introduce you to a new acronym – PAAS or Positioning as a Service!

The DA2 is the second-generation receiver and antenna for Trimble’s Catalyst service. Simply, Catalyst is a revolutionary, GNSS concept delivering positioning as a service to mobile devices. It turns your Android or IOS device into a precision mapping, navigation and measurement tool that you can use with any location enabled app or service including KOREC Capture and Esri FieldMaps.

Catalyst delivers the most cost-effective method for achieving cm accuracy positioning in the industry.

Subscription based services have grown faster than traditional businesses in many areas of the economy. Trimble is leading the way in PAAS with its Catalyst positioning service.

Of course, here at KOREC we don’t just take things at face value so our Mapping Business Area Manager, Richard Gauchwin, has been out and about putting the DA2 through its paces.

We caught up with him to find out what’s new and what’s impressed. Here’s his verdict:

1. Number one has to be the fact that the DA2 is now a full GNSS receiver which removes dependencies on the mobile device which you may have seen with the DA1.

Whilst the DA1 connected via a cable into an Android phone, it was the app on the phone where all the GNSS processing was carried out. In short, processing times etc were limited by the phone’s performance. Not so with the DA2 receiver, it’s a whole different story! The biggest plus is that Catalyst is now so much faster to use. For example using the DA1, it might take you minutes to get a position, with the DA2, we’re talking seconds!

They may look the same and still weigh in at just 330g, but in terms of performance they couldn’t be more different.

2. The DA2 brings you far more flexibility as it now has Bluetooth which allows you to connect wirelessly to your mobile device of choice. And believe me, there is definitely more choice because this now means that the DA2 is compatible with both IOS and Android.

3. The DA2 offers Trimble’s ProPoint technology which has previously only been available in top of the range GNSS receivers. ProPoint means better results in harsh GNSS conditions, for example near tree canopy and in built-up areas. Expect a cm position near tree canopy within 40 seconds.

4. New subscription choices mean even better scalability. Subscriptions have been clarified to accommodate the better accuracies achievable. Choose from 60cm, 30cm, 10cm or 1cm. Trimble have also provided more choice in the number of hours you can purchase including some great options available for equipping large workforces. And of course, you still only pay for what you use.

5. The DA2 means that you are no longer reliant on receiving your cm corrections over an internet connection. Thanks to Trimble’s RTX technology you can now get your corrections via satellite which is great for areas with limited mobile phone coverage and internet connectivity.

6. The DA2 is future proof and will update wirelessly when required.

Who is Catalyst suitable for?

In a nutshell, we describe Catalyst as being a truly cost-effective option for those who require high accuracy positions as a part of their workflow, for example, positioning Ground Control Points for an aerial mapping project, recording the location of soil samples on a construction project or positioning valve or pipe connections on a drainage job. By having access to a cm accuracy system, with no training costs and no outlay for expensive, specialist hardware, Trimble Catalyst is truly a system that can put cm accuracy into the hands of the many different users and/or across large workforces.

We have a great analogy comparing Catalyst to a buying a printer and printer inks. Simply, the hardware costs in buying a printer are minimal, the service, or in this case the printer ink is where the cost lies. If you are just printing out two or three pages every now and again then this is the equivalent of a Catalyst user who can really gain value from the system. If however, you print off many full reports every day, then you will not achieve good value from Catalyst and it’s best to consider a dedicated survey grade GNSS.
