  • 7 min read

Release Update – February 2022

This is a marXact monthly update for our clients!


As a UNI user, we want to help you to get the most out of your receiver. We hereby send you the Release Update mail for December, and tell you everything about the features and improvements that become available during this month. 

We keep you informed about new functions and possibilities, conveniently collected in one comprehensive mailing, and on a monthly basis. In these mailings, we tell about what becomes possible and what improvements have already been implemented.

We combine these releases and updates and how they’ll improve your digital surveying experience in monthly updates: these Release Update mailings. In this edition, we tell you about a number of new functions that have gone live recently and improvements that we have made to the UNI-Solutions. We tell you more about the 4G hardware upgrade that UNI users benefit from, the change in the possibilities of the NFC, and coloured options when switching your UNI-GR1 on and off.

Feel free to forward this e-mail to colleagues who survey with the UNI-GR1 and/or process data in the UNI-Cloud, so that they are also informed of what’s to come or could register for our upcoming Demo Drinks on April 14th.

4G hardware upgrade

In eerdere Release Update mailings vertelden we al over de verandering van 3G naar 4G, de nieuwe standaard voor internetsnelheid en -toegang. UNI users kunnen kosteloos deze overgang maken door een speciale 4G hardware upgrade te bestellen bij ons. Hiervoor hebben zij een mailing ontvangen waarin stap-voor-stap wordt uitgelegd hoe je de gratis upgrade bestelt. De verzending van de upgrades begint binnen een paar weken.

Wij zeggen vaak dat wij het belangrijk vinden om een optimale inmeetervaring te creëren en daar draagt inspelen op (zulk soort) veranderingen, aan mee. Zo blijf je het meest uit je UNI-Solutions halen.

New NFC possibilities

We have slightly adjusted and expanded the possibilities of the NFC tag. To ensure that you can survey throughout the day, we have developed an energy-saving function. The NFC tag no longer works by default. From now on, you first go to the discovery mode by pressing the ‘on’ button for 15 seconds, then the LED ring turns blue, and the tag is linked to your UNI-GR1. By adding the NFC tag to the discovery mode, there is one less standard function to load. As a result, your battery is used less and you have extra energy left for digital surveying.

Do you want to continue working with the NFC tag? Making the connection remains as easy as you are used to from us!

Boot animation

This recently launched feature makes it possible to see even better if the UNI turns on. After pressing the power button, the LED ring will ‘spin’, will slowly turn green in the start-up phase, and end when the UNI has completely started up. How convenient is that?

Energy saving

Thanks to one of our newest features, you can save even more battery power! If your battery is 20% or less, the LEDs will automatically dim and at 10% or less even more. This saves your battery and gives an extra indication that you can the charger ready. This feature is integrated in the next UNI-Connect update, which will be released in a few weeks.

STM update

This update is more technical and is on its way. You will see when updates will be installed soon, we have done a lot of work on improving the internal coprocessor for this. When you turn off your UNI-GR1 and the LED ring starts to ‘spin’ white, you know that the most recent update is being installed. You don’t have to be shocked when you see the ring ‘jump’, it’s just a sign of your new measuring possibilities!

In time, machine control

Okay, okay. This is more of a long term plan, but a lot of fun anyhow! We are researching the possibilities for machine control with a partner. In this case, a UNI is mounted on (for example) an excavator and data can also be measured in this way. This is a long process, but too good not to share – especially because this question has come from the work field.

What steps do you need to take?

Not a lot, if we are completely honest with you. All updates are done automatically and while you are out surveying in the field or preparing tasks in the office. You might need to turn your UNI-GR1 off and on again, but only when the update stops unexpectedly. After turning it on again, you are good to go.

More releases coming up

We have more releases coming up next year, including expanding the UNI-Cloud project measuring and editing possibilities, importing and exporting even easier and the previously announced UNI-Collect surveying app. More on this in future Release Updates!

We will send you a new email full of information about new functions and improvements next month, so that you are able to take full advantage of these new possibilities as well.
