Many surveyors have come to depend on the connectivity, consistency and quality of the Trimble VRS Now correction service, and for a good reason: it works. It is a solid, proven, cost-effective tool pioneered by Trimble that has been used across the globe for over 20 years.
Today, Trimble harnesses the power of more satellites for its customers’ real-time corrections stream than ever before for a more robust result. It does all this without the need for a base station, simplifying job site logistics, saving time and keeping expenses down.
But what happens 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.
Expect the unexpected
In the world of surveying, every moment in the field counts. For those who aim to lead in this field, there is no such thing as being over-prepared. Being able 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 ten years ago, surveyors promptly adopted Trimble xFill technology as a solution that minimizes 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 the ITRF to the VRS Now datum. This offset then makes it possible to continue using RTK GNSS in the 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 to handle longer interruptions to the correction stream that stretch beyond five minutes?
Trimble xFill maintains the local coordinate system and provides positioning insurance so that production continues even when the cellular signal is not dependable. Customers who have subscribed to the CenterPoint RTX correction service can utilize the xFill solution beyond the five-minute limit and can continue surveying at centimetre-level accuracy until the primary correction stream is restored.
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 traditional RTK methods, CenterPoint RTX acts as a positioning backup in the field so that customers benefit from its satellite-delivered dependability and complete independence from terrestrial correction sources or infrastructure.
Taking the VRS Now promise ‘Connect. Correct. Measure’ one powerful step further by layering on the worry-free PPP backup means that the 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, allowing its customers to get the job done on time and budget.
Benefits
This has many benefits, including no unwelcome surprises on arriving at a new job site and discovering there is no cellular coverage. Customers can keep working confidently through cellular interruptions with centimetre-level accuracy indefinitely – until the original correction stream is restored. As a result, no precious time is lost and no deadlines are missed due to circumstances outside of your control and there is no need to worry about remote sites, terrain obstructions, long baselines, signal congestion or outages.
Make reliability your position
It pays to do the job right the first time. After all, time is money and that is why our customers use Trimble VRS Now in the first place. The strategic pairing of Trimble VRS Now and CenterPoint RTX provides an additional layer of redundancy, preparing surveyors for any unforeseen challenges. Having a backup solution – an ultimate positioning insurance in the field – is more than just a safety net. It has been and continues to be a game-changer that keeps you productive and profitable.
