In the more than 100+ articles I’ve written for GPS World magazine over the past seven years, I don’t think I’ve ever written about a new product introduction like you will see below. I tend to focus on GNSS and geospatial technologies rather than a brand-specific products and services. In fact, last week I had an outline prepared for my article that included some really cool free and useful GPS/GNSS apps. I decided to set that outline aside until later, in favor of writing about this product.
Although certainly different than mainstream GPS/GNSS receivers, I wouldn’t refer to this new product as a disruptive one (a marketing term used to describe something that is industry-changing) and it doesn’t incorporate leading-edge GPS/GNSS technology. In fact, it’s relatively low-tech in comparison to the other GPS/GNSS surveying receivers available in the marketplace.
Even more fascinating is the fact that the product was developed not by any of the mainstream GPS/GNSS receiver manufacturers you hear about today, but rather an electrical engineer from Utah who leveraged the design/manufacturing expertise of one of China’s largest manufacturers of GPS/GNSS surveying receivers.
The final nail in the coffin is the fact that I’ve expended thousands of words in GPS World denouncing the future of post-processing and celebrating the virtues of high-precision, real-time GNSS (RTK, SBAS, PPP) receivers.
I tried to talk myself out of writing this article more than once, telling myself that I’ve never written specifically about a new product and I wasn’t going to start now. But, as much as I didn’t want to, I always came back because it is so darned compelling.
While the product is not aligned with my vision of real-time being the future of high-precision GNSS receivers, it is perfectly aligned with my vision that the cost of high-precision GNSS receivers are dropping and will continue to decline considerably over the next few years.
The product is the X90-OPUS GPS receiver.
It does not use leading-edge GPS technology.
It’s not sexy.
It’s not perfect.
However…it is incredibly inexpensive, and it is designed to be perfectly simple to operate.
In one sentence, the X90-OPUS is a one-button, dual-frequency GPS receiver that is specifically designed to use the National Geodetic Survey’s free online OPUS post-processing service to achieve centimeter-level GPS positioning anywhere in the United States and surrounding countries.
You might say to yourself, “So what? There are plenty of GPS receivers on the market that are capable of providing this functionality.” I would make the same comment, except it has one product feature that I’ve never seen before.
What makes the X90-OPUS so compelling is its low cost. The X90-OPUS GPS receiver sells for US$2,450, including all software and accessories (except for tripod/tribrach) that allow you to submit GPS data files to OPUS in a very automated fashion.
At US$2,450, the X90-OPUS may open a new world for surveyors, engineers, and scientists who have previously shunned high-precision GPS receivers due to their high cost and complexity.
For those of you who yearn for the yesteryear of the one-button Ashtech’s legacy Locus GPS receiver, the X90-OPUS reminds me of that sort of simplicity, but on steroids. The X90-OPUS is a dual-frequency (L1/L2) receiver, while the Locus was a single-frequency receiver. The difference is that one can use OPUS and the other cannot. OPUS post-processing doesn’t support single-frequency GPS receivers. However, Mark Silver, the electrical engineer from Utah, has taken it a step further by developing software that automates the OPUS data submission process. Although I’ve made it clear in the past that I’m not a fan of post-processing, it doesn’t get any easier than this. You don’t need to buy a base station, and you don’t need to own post-processing software. It’s a two-button push operation: once to turn it on, and once to turn it off.
The X90-OPUS receiver was characterized by the National Geodetic Survey back in March 2013 and is listed on the NGS’s Individual Antenna Calibration website.
You might think that with the US$2,450 price point and not being offered by a major GPS receiver manufacturer, this is some home-brew GPS receiver. If you thought that, you would be incorrect. The GPS engine in the X90-OPUS is a Pacific Crest BD950, the same engine found in many receivers from other GNSS system manufacturers. CHCNav integrated the GPS engine into its casing to produce the X90 receiver. However, Mark added his own special sauce to the X90 to turn it into the X90-OPUS so this isn’t just a CHCNav receiver being marketed by iGage (Mark’s company).
In all fairness, I’ve not touched the X90-OPUS yet. I likely will in the next few days. However, unless the hardware is unreliable, I don’t see how this product is not going to be a winner, and it will introduce high-precision GPS receivers to an entirely new group of surveyors, engineers and scientists who have been holding out on using GPS.
Webinar This Thursday
Date: Thursday, June 20, 2013
Time: 10 a.m. PDT / 1 p.m. EDT / 6 p.m. GMT
Summary: A look at the challenge of dealing with horizontal datums in your GIS. We are moving into a new era in dealing with datum transformations. Geodata 2.0 is coming, and it can create big headaches when attempting to combine disparate geospatial databases. Sensors such as GPS receivers, remote sensing imagery, and 3D scanning provide much more accurate data, setting up a collision with outdated and mismatched legacy horizontal datums.
