JAVAD GNSS has launched a new version of the TRIUMPH GNSS receiver, which features 864 channels — more than any receiver it has yet offered. The TRIUMPH-LS land survey receiver offers, in addition to the 864 GNSS channels, three powerful processors, 256 I/O, 24 digital filters, 24 anti-jam filters and 14-MB program memory all in a single chip, which uses less power and makes the total system less expensive, according to the company.
The announcement was made at the ION GNSS+ Conference, being held this week in Nashville, Tennessee.
Javad Ashjaee, CEO and founder, explained the decision to incorporate 864 channels. “Some questioned the need for the 216 channels. They now realize the need for 440 channels. We assign multiple channels to each satellite for redundancy and reliability. We use more than 100 channels to scan GNSS bands for interference — 864 channels is the key to reliable performance.”
The TRIUMPH-LS provides visual stake-out, six parallel RTK engines, more than 3,000 coordinate conversions, advanced coordinate geometry features, and rich attribute tagging on a high-resolution 800 x 480 pixel display. When used in photogrammetry, offsets can be calculated using the internal camera for 10-centimeter accuracy, or an external camera for 5-centimenter accuracy. TRIUMPH-LS is the first JAVAD GNSS receiver to offer photogrammetry for land survey.
Other features include versatile attribute tagging, feature coding, automatic photo and voice documentation, and an interference monitoring and reporting feature.
The TRIUMPH-LS has a battery life of 25 hours in RTK rover mode with full screen brightness and UHF/GSM. Two hours of charge equals two days of surveying. The internal batteries are field serviceable and can be easily replaced by the user when needed.
The TRIUMPH-LS, including batteries and pole, is the lightest GNSS RTK receiver in its class, according to JAVAD GNSS. The total weight of the system — including radio, controller, pole and 25 hours of internal battery — is 2.5 kilograms.
Built on a tough magnesium alloy chassis, all connectors, SIM cards, and micro-SD cards are protected against harsh environmental conditions. The pole can be collapsed and the unit can easily fit in a car seat — there are no long poles and no separate controller or brackets to disassemble.
The TRIUMPH-LS automatically updates all firmware when connected to the Internet via Wi-Fi. The built-in GNSS full tracking antenna has a large ground place and excellent centering and rotational performance.
To learn more about the TRIUMPH-LS, stop by the JAVAD GNSS booth (Booth D) in the ION GNSS+ Exhibit Hall now through Friday.Presentation will be given Thursday at the conference room of the exhibition hall at 2:00 pm.

Raven Aerostar has integrated Septentrio’s AsteRX2eH into its tethered aerostat system.
Septentrio announced today that Raven Aerostar, a manufacturer of Lighter-Than-Air (LTA) platforms, has successfully integrated Septentrio’s AsteRx2eH, a single-board dual-antenna GPS/GLONASS heading receiver, into its tethered aerostat systems.
Raven Aerostar recently completed a maritime persistent surveillance solution demonstration, deploying a TIF-25K aerostat system aboard the High-Speed Vessel — SWIFT (HSV-2), during which the AsteRx2eH performed remarkably, according to the companies. Integrating the single-board AsteRx2eH dual-antenna receiver to replace a solution based on two separate GNSS receivers allowed Raven Aerostar to achieve a reliable and accurate heading solution while also decreasing deployment time and total cost of GNSS sensors.
The AsteRx2eH provides a compact and low-power solution for precise positioning combined with accurate heading information, produced at a high output rate. The tracking of both GLONASS and GPS satellites allows the receiver to improve the availability and robustness of a solution in challenging environments.
The AsteRx2eH is a globally acclaimed OEM solution with field proven performance for land, marine and aerial applications, Septentrio said. It is used onboard helicopters and aerostats during stabilized flights hovering at low dynamics, where inertial sensors cannot easily provide a drift free solution. Another application is delivering reliable heading information for driverless ground vehicles, even at very low speeds.
“From its user interface to its accuracy and durability, Septentrio’s AsteRx2eH receiver has proven to be an exceptionally stable system,” commented Patrick Lokken, Engineering Technician at Raven Aerostar. “We have integrated the AsteRx2eH into our lighter-than-air applications in multiple environments including desert and maritime, and have yet to see it falter.”

Hemisphere GNSS has launched its new Crescent Vector H200 GNSS compass module, a high-performance receiver for heading, positioning, heave, and attitude. Vector H200 is designed for professional marine, navigation, and land applications in challenging and dynamic environments.
Vector H200 processes L1 GPS and GLONASS signals to deliver precise heading, greater positioning reliability, and better performance in challenging environments, Hemisphere GNSS said. Through using two separate antennas, Hemisphere GNSS’ patented Vector technology computes the heading and pitch or roll angle while stationary or in motion. Vector H200 can compute heading accuracy to 0.02 degrees using a 5-meter antenna separation. A variety of differential correction methods also make it possible for Vector H200 to provide sub-meter to centimeter position accuracy.
Marine industry developers can maximize performance by integrating Vector H200 into their systems for hydrographic and bathymetric surveys, auto-pilots, dredging, and buoys. For land applications, Vector H200 is ideal for aligning cameras, antennas and projectiles, and for machine control applications in agriculture, construction, and mining.
“System integrators have a lot to gain from Vector H200’s powerful combination of navigation and machine control orientation capabilities,” said Ron Ramsaran, Sr. Product Marketing Manager at Hemisphere GNSS. “They will appreciate the performance and value from such a small board package.”
Vector H200 supports SBAS, L-Band and RTK differential positioning solutions and features our exclusive SureTrack technology optimizing the use of GPS and GLONASS signals. Hemisphere GNSS offers precise GNSS antennas to fit a variety of Vector H200 applications.

L1-RTK-systems is a solution that allows our handheld users to use 2/L1 high sensitive GNSS handhelds working as base and rover to achieve 2-20 cm level accuracy. This is a reliable and cost-effective solution for field workers, Nexteq said.
NovAtel’s single-box SPAN-CPT GNSS/INS receiver now supports the company’s next-generation OEM6 GNSS technology platform. The OEM6 GNSS engine significantly improves positioning performance through its support of GPS and GLONASS, all-in-view satellite tracking and intelligent measurement selection, the company said.
“We kept the design of the enhanced SPAN-CPT identical to our legacy product to ensure a seamless upgrade process for our customers who would like to take advantage of the improved positioning capabilities,” said Jason Hamilton, NovAtel director of marketing. “The enhanced SPAN-CPT is fully backwards compatible with the previous generation of product. It retains the same compact form factor with identical pin-out and log structure.”
As with the previous generation product, the upgraded SPAN-CPT integrates NovAtel’s precision receiver technology with fiber optic gyro and MEMS accelerometer inertial components from KVH Industries in one compact unit. The tight-coupling of the GNSS and INS technologies optimizes the raw GNSS and IMU data, delivering a superior position, velocity and attitude solution, NovAtel said. Comprised entirely of commercial components, the SPAN-CPT minimizes the operational complexities of working across international boundaries.
Production of the OEM6 supported SPAN-CPT begins June 1.

Furuno Electric Co., Ltd., has announced that new multi-GNSS receiver chips eRideOPUS 6 and eRideOPUS 7 will be available in August. The new receiver chips are multi-GNSS compliant single-chip LSIs, capable of concurrently receiving signals from multiple satellites in GNSS systems and satellite-based augmentation systems, as well as Japan’s Quasi-Zenith Satellite System. Both chips receive signals from GPS and Galileo; the eRideOPUS 7 also receives GLONASS signals.
The ability of concurrently receiving GNSS/GNSS augmentation signals from multiple satellites from different satellite services means that the receivers have more probability of acquiring a greater number of satellites at any single time. Subsequently, position stability as well as accuracy will be greatly improved, minimizing the chance of a position lost. Also, the receiver chips incorporate an enhanced level of noise rejection capability, implementing the anti-jamming function as well as the improvement of multipath mitigation.
Time-to-first-fix capability of the existing eRideOPUS 5 (no more than 1 second when hot started) is retained in these new receiver chips with a combination of A-GPS compatibility and self-ephemeris extraction. Moreover, the position update rate of the new receiver chips is greatly improved, achieving a 10-Hz update (every 0.1 second), which is twice as fast as the capability achieved by eRideOPUS 5.
The new receiver chips are capable of dead-reckoning navigation, using a gyro sensor and vehicle speed pulse signals, a gyro sensor and an acceleration sensor, and wheel tick data taken from a CAN-Bus network, achieving high positioning accuracy even in locations where satellite signal reception is not available, such as inside tunnels.
In May 2013, Furuno is planning to start the delivery of evaluation kits for the receiver chips so that third-party manufacturers can evaluate the feasibility of incorporating the receiver chips into their products, and in August 2013, the new compact GNSS receiver module GN-86/GN-87 as well as
dead-reckoning-capable GV-86/GV-87, using these new receiver chips, will be made available for automotive navigation systems as well as eCall systems.
NovAtel Inc., supplier of OEM GNSS components and subsystems, has announced the addition of a new commercially exportable MEMS IMU to its line of SPAN GNSS/INS products. Available for immediate shipping, this custom Analogue Devices MEMS inertial sensor is exclusive to NovAtel, and can be paired with an OEM6 receiver card to provide continuously available position, velocity and attitude (roll, pitch, yaw) in a small, single-unit form factor.
SPAN tightly couples NovAtel’s precise GNSS technology with highly accurate inertial measurement technology to provide a robust, stable and continuous 3D navigation. The new OEM-ADIS-16488 sensor is designed to be coupled with NovAtel’s OEM6 receivers via the MEMS Interface Card (MIC), providing integrators with a compact, powerful GNSS/INS engine, NovAtel said.
The OEM-ADIS-16488 features low noise gyros and accelerometers in a small, lightweight form factor. This IMU enables precision measurements for applications that require low cost, high performance and rugged durability. Tight-coupling of the two technologies enables continuous robust positioning in difficult environments where satellite signals are unreliable or unavailable for short periods of time.
The OEM-ADIS-16488 is now available for order and immediate shipment.
For quite some time, I’ve been writing in GPS World magazine and speaking at conferences about the declining prices of high-precision GNSS receivers and how the cost of high-precision data (especially vertical) is going to decline substantially. For my colleagues in Asia, Africa, Europe, and South America, you’ve already seen this. Dual-frequency, multi-constellation GNSS receiver prices in those areas are significantly lower than in the United States and Canada.
Previously, I’ve presented to you that I think dual-frequency (L1/L5), dual-constellation (GPS/Galileo) GNSS receivers will be inexpensive in the future. My reasoning, simply, is that L5 is an open signal (legacy L2 is not) and supported by both GPS and Galileo. Furthermore, both GPS and Galileo use a CDMA radio technology, so designing a GPS/Galileo receiver is a heck of a lot easier than a GPS/GLONASS receiver. Therefore, unlike today’s GNSS receiver competitive landscape of only a dozen or so manufacturers of high-precision GNSS receivers, there will be dozensssss (emphasis on s) and maybe hundreds of high-precision GNSS receiver manufacturers, based on oodles of L1/L5 GNSS chipsets that are sure to come.
Will all GNSS chipset designers decide to expend the extra energy it takes to optimize their chipset for RTK FIX or Float solution? No, but certainly there will be “boutique” GNSS chip designers that will specialize in high-precision designs. It likely won’t be the companies selling a $3 GNSS chip to Apple or Samsung today. Those companies rely on selling tens (or hundreds) of millions of GNSS chips per year. I’m talking about companies that can survive on selling hundreds of thousands of high-precision GNSS chipsets for $50-100 each.
However, Galileo is still at least two years from a minimal usable constellation and the GPS operator, the U.S. Air Force, is in no hurry to launch GPS satellites with new capabilities (for example, L5) — so low-cost, high-precision GNSS chipsets are still a couple of years away. If this is the case, then why are high-precision GNSS receiver prices declining in some areas today?
As I mentioned before, our colleagues in Asia, Africa, Europe, and South America are already seeing lower-cost high-precision GNSS receivers. There are brands offered in those geographic regions that aren’t known (or are very little known) in the U.S. and Canada. Brands like Stonex, FOIF, BHCNav, CHCNav, and others market themselves outside of the U.S. and Canadian markets, but not much in the United States or Canada. The increased competition in those foreign markets has driven high-precision GNSS prices down.
The CHC booth at Intergeo 2012.
The reason high-precision GNSS prices are still high in the U.S. and Canadian markets are because it’s still primarily a Trimble, Leica, Topcon game. Yes, there are other brands like Ashtech/Spectra-Precision, SXBlue, Javad, Sokkia, Hemisphere, Altus, and Navcom, that may offer entry-level entry points, but the Big Three still dominate the U.S. and Canadian markets, partly because of their broader product lines and mostly because they have the best network of dealers. Differing from the others in this mix is Navcom, a subsidiary of John Deere & Co. Navcom’s GNSS technology is distributed by Deere & Co, and is focused almost exclusively on the agriculture market.
In the United States and Canada, high-precision GNSS receiver users are still willing to pay a premium for leading brand-name products and their dealer networks. You might think that there’s a lot of price pressure from the other brands. There is some, but some of the other brands are owned by the big boys. Trimble owns Spectra-Precision and Ashtech. Topcon owns Sokkia.
Spectra Precision (here at Intergeo 2012) is owned by Trimble.
For there to be serious price movement in the United States and Canada as there has been in other areas of the world requires more competition. I think we’re going to start to see more of that.
I know you don’t want to hear this, but the competition for high-precision GNSS receivers is coming from China — and it’s serious competition. Chinese GNSS receiver manufacturers are already well-established in Africa, Europe, and Asia (of course). Their high-precision GNSS gear is coming soon to a place near you.
What exactly is a Chinese-made GNSS receiver? Mostly, they are receivers made using the guts (GNSS receiver boards) from mainstream GNSS receiver designers like Trimble, Topcon, NovAtel, and Hemisphere. The Chinese companies buy these receiver boards and design their own cases, battery packs, and other supporting systems around the GNSS receiver board. The finished products, like the CHCNav X91, look much like what you see from Trimble/Topcon/Leica today, and it sports a Trimble or Novatel GNSS receiver inside, for fraction of the price you’ll pay for the equivalent Trimble GNSS receiver.
Of course, you wouldn’t benefit from Trimble (or whomever) dealer network support, and you would be risking that the manufacturer has designed a reliable system around the GNSS receiver board. What happens if the receiver needs service? Where’s the nearest support center? Who do you call? These are all very valid questions that any prudent businessperson would ask themself before making a significant equipment purchase.
Some of the Chinese manufacturers rely on low price to attract your attention and then offer minimal customer support. Others, like CHCNav, are addressing this by setting up regional centers around the globe for support and repair. Can they produce high-quality GNSS products that will meet the expectations of U.S. and Canadian buyers? The reputation of Chinese manufactured products in the surveying market is not very good. Will they have the staying power to hang on for a few years, long enough to gain the confidence of U.S. and Canadian users?
In their favor is their home market. China is the largest consumer of high-precision GNSS receivers in the world. In fact, it’s been said that more high-precision receivers are sold in China than in the rest of the world combined. Even if that’s not an accurate statement, it’s not incorrect by very much. That tells you something about the size of the Chinese market for high-precision receivers. With a market that size, I think it’s safe to say that Chinese receiver manufacturers are gaining a lot of experience in designing and manufacturing GNSS receivers, and one can assume that the next-generation receiver design is better than the previous one.
While they haven’t quite ventured into offering their own GNSS receiver designs (still buying GNSS receiver “guts” from established manufacturers), last week one Chinese manufacturer took a step closer to doing so. On January 31, Hemisphere GPS announced that Beijing UniStrong Science & Technology Co Ltd. is acquiring Hemisphere’s core GPS design/manufacturing business. Hemisphere has chosen to divest itself of all non-agriculture related businesses and rename the company AgJunction, the same name as a software company it acquired recently. Of course, GNSS technology is highly related to agriculture, and there’s no doubt that AgJunction will continue to use GNSS technology, but clearly the AgJunction management team doesn’t think it’s an important enough technology to have to own it.
UniStrong is no stranger to the GPS/GNSS business and is no small fry. It’s been in business since the mid-1990s and boasts more than 1,000 employees, offering a wide variety of high-precision GPS/GNSS receiver solutions from handheld GIS receivers to full-blown RTK GNSS receivers. With this acquisition (US $15 million), it becomes the first Chinese-owned GNSS receiver design/manufacturing group in North America.
Thanks, and see you next time.
