 * Trimble xFill maintains your local coordinate system, and provides positioning insurance so that you remain productive, even when your cellular signal is not dependable. Customers who have subscribed to the CenterPoint RTX correction service will be able to utilize the xFill solution beyond the 5 minutes limit and can continue surveying at centimeter-level accuracy until their primary correction stream is restored.

You’ve come to depend on the connectivity, consistency, and quality of Trimble VRS Now correction service—and for a good reason: it works. It’s a solid, proven, cost-effective tool pioneered by Trimble and used across the globe for over 20 years.

Today, we harness the power of more satellites for your real-time corrections stream than ever before for a more robust result. All this without the need for a base station, simplifying job site logistics, saving time, and keeping expenses down.

But what do you get when you combine the Trimble VRS Now GNSS correction with the Trimble CenterPoint RTX correction service? The answer is “Peace of mind with an added layer of reliability that keeps you from missing a beat in the field”. Let’s take a closer look at this. 

Expecting the unexpected

In the world of surveying, every moment in the field counts. For those who aim to lead in this field, there’s no such thing as being over-prepared. Having a way to address challenges in the field— eliminate downtime and maintain seamless operations—is not just a strategy. It’s a mandate.

When introduced and embedded in premium Trimble GNSS receivers over 10 years ago, surveyors promptly adopted Trimble xFill technology as a solution that minimizes their downtime. xFill technology allows the correlation of the VRS Now datum to the geocentric International Terrestrial Reference Frame (ITRF) used by Trimble RTX to converge a precise point solution and calculate the offset from ITRF to the VRS Now datum.  This offset then allows you to continue utilizing RTK GNSS in your VRS Now datum after a loss of cellular Internet by utilizing the corrections in the Trimble RTX solution to mitigate biases. While Trimble xFill is invaluable for covering short interruptions, it will time out after five minutes of use. So, how do you handle longer interruptions to your correction stream, those stretching beyond five minutes?

The Best of Both Worlds

Powered by the same technology as the xFill correction service, Trimble CenterPoint RTX is a premium GNSS correction that takes the reliability and functionality of the xFill solution to new heights. Complementing your traditional RTK methods, CenterPoint RTX acts as your positioning backup in the field so you benefit from its satellite-delivered dependability and complete independence from terrestrial correction sources or infrastructure. 

Taking VRS Now promise “Connect. Correct. Measure.” one powerful step further by layering on the worry-free PPP backup, means CenterPoint RTX correction service will “fill in” and effectively bridge local signal interruptions, congestion, or cellular outages with high-accuracy positioning for the entire duration of unexpected connectivity disruption in the field, so you can get the job done on time, and budget. 

What does this mean for you?

• No unwelcome surprises, such as arriving at a new job site and discovering that you don’t have cellular coverage.
• Keep working confidently through cellular interruptions with centimeter-level accuracy indefinitely—until the original correction stream is restored.
• No precious time lost or deadlines missed due to circumstances outside of your control.
• No need to worry about remote sites, terrain obstructions, long baselines, signal congestion or outages

Make reliability your position

You know that it pays to do the job right the first time. After all, time is money and this is why you use Trimble VRS Now in the first place. The strategic pairing of Trimble VRS Now and CenterPoint RTX arms you with an additional layer of redundancy, preparing you for any unforeseen challenges. Having a backup solution—an ultimate positioning insurance in the field—is more than just your safety net. It has been and continues to be, a game-changer that keeps you productive and profitable.
