Juniper Systems Pulls Cedar Tree Under Its Banner
The CT4 and other rugged handhelds by Cedar Tree Technologies will now be available through Juniper Systems.

Juniper Systems is merging its subsidiary company, Cedar Tree Technologies, into Juniper Systems. The move will allow customers to purchase Cedar’s Android-operated rugged handhelds directly from Juniper Systems.

Juniper Systems launched Cedar Tree Technologies as a rugged handheld company in August 2014.

“With a reputation for top-of-the-line, ultra-rugged handheld computers, Juniper Systems aimed to expand its products to meet the needs of customers who may not need the outstanding level of ruggedness or support that Juniper handhelds provide. And that’s how Cedar Tree Technologies began. Cedar handhelds lie somewhere between consumer devices and Juniper Systems’ ultra-rugged handhelds, providing a mesh of both ruggedness and affordability,” said a statement from the company.

Cedar handhelds run on the Android operating system, offering access to thousands of business-ready apps and Google services via the Google Play Store. This provides users with an off-the-shelf product, eliminating the need to download third-party data collection software. Juniper Systems has published a blog post that outlines the differences between Cedar and Juniper handhelds.

The Cedar product line that Juniper Systems will now be carrying includes three new handheld devices:
- CT7 Rugged Tablet. Featuring a large, 7-inch display, the CT7 tablet is IP67 waterproof and dustproof, and is priced at $899 USD.
- CT4 Rugged Handheld. The CT4 handheld is a more compact device than the CT7. Featuring a 4.3-inch display and an IP68 waterproof and dustproof rating, it is priced at $489.
- CMP1 Miniphone. The CMP1 Miniphone is rated IP65 (dustproof and resistant to water), and is ideal for swapping out a regular smartphone for outdoor excursions, for kids, or for use as an emergency phone. The CMP1 sells for $124.

Hemisphere GNSS Releases Next-Generation GNSS RTK Engine
Hemisphere GNSS has released Athena, its next-generation GNSS engine. Offering significantly enhanced performance, Athena provides Hemisphere with a new, future-oriented foundation providing strong performance, flexibility and reliability, according to the company.

Athena has yielded outstanding performed in virtually every environment where high-accuracy GNSS receivers can be used, the company stated. Hemisphere customers have tested Athena’s performance in long baseline, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation.

Hemisphere has designed its new core engine to maximize the company’s ability to excel at the rigorous GNSS requirements in multiple market segments, supplying its customers in machine control, survey and GIS, with a design for now and in the future, Hemisphere said in a statement.

The release of Athena is a significant milestone for Hemisphere, which promises another new product entry into the market in the coming months.

Features of Athena include these capabilities:
- Initialization time — A reliably consistent initialization performance, less than 15 seconds at better than 99.9 percent reliability.
- Robustness in difficult operating environments — Extremely high productivity under the most aggressive of geographic and landscape oriented environments for GNSS, while delivering up to 50 percent better performance in user tests matched against competitive systems.
- Performance on long baselines — Position stability for long baseline applications, with position quality often times exceeding the performance of other leading RTK systems on the market.
- Performance under scintillation — Sustained accuracy under ionospheric scintillation activities, providing one of the most reliable means to work with GNSS in scintillation-affected areas.
Rodrigo Leandro, Hemisphere’s director of engineering, GNSS Positioning Systems, gave this description of the design process for Athena.

“Development of Athena started shortly after I came to Hemisphere in August of 2013. The company has been a leader in RTK solutions for many years. During those years, we focused in certain specific market segments such as agriculture, and under new leadership we determined there was a need to address a wider spectrum of market segments, with very high accuracy and feature rich capabilities built on the strong legacy platform we had already established. So, working with Mike Whitehead, the company CTO and our main RTK technologist, we identified the goal of reengineering our RTK engine to match the needs of RTK for the next 10 years, and to provide a foundation for future product development.”

Leandro continued, “As part of this, we made a decision to build an expanded, world-class software development team, pulling great talent from around the industry to create a group of 11 totally focused on what we should do to move GNSS technologies forward — looking at all types of positioning techniques, not just RTK. Athena is just the first result of that work to become publicly available — you will see plenty more coming from the team over time.

“Looking at Athena specifically, we did a complete review, touching every part of the engine — from how we deal with the atmosphere, quality-control of the data, modeling the clock of the receiver, and so on, through to how to do external corrections, whether single-based or network-based. We even looked at and modified the receiver system, improving the multitasking architecture to more actively use the CPU for our computational work,” Leandro said.

“I’m proud to say that the results of all that work match up to what we envisioned. RTK is a pretty mature technology at this point, so improving on what is available in the industry is a tough ask. However, our extensive competitive testing shows that the engine performs really well in terms of initialization, accuracy, and stability across a range of different environments, for instance in long baselines and under tree canopy, and our tests of scintillation are showing great results as well. Overall, we have seen excellent accuracy coming out of this engine compared to legacy as well as others in the marketplace. It’s hard to win every single time in a toe-to-toe comparison, as systems and conditions differ in every test, but our broad testing shows us not only matching, but beating competitive systems pretty consistently.”

“In our user base, both Hemisphere branded products and our OEM boards, we get exposed to a wide variety of applications and environments, from agriculture and marine, through machine control applications and survey systems,” Leandro said. “Our goal from the start was to build a system that performed across that user base, and we are proud to say that we have delivered with Athena.”

“In terms of availability, we want to get the Athena engine on as many current and legacy systems as possible, so our users have the best possible experience. However, we have also been improving the legacy engine as well, delivering gradual steps of improvement to our customers, so whatever version they are using, their experience should be much improved,” Leandro concluded.

Test Reports

Hemisphere GNSS provided the following statements by an independent tester and from customers, widely distributed around the industry.

“I’ve had an opportunity to thoroughly test Athena in both moderate and extreme environments,” said Andy Carbognin, an independent GNSS test specialist at Vecto Geomatics of Ottowa, Canada. “I’m very impressed with the performance, and we’ve tested alongside the current industry leaders’ top-of-the-line products. In every situation, Athena is proving to be a tremendous improvement over Hemisphere’s most widespread legacy firmware versions, at a minimum, matching the industry’s best while in many cases exceeding their performance.”

“Carlson Software has extensively tested Hemisphere’s new Athena RTK engine on the Carlson BRx5 GNSS receiver,” said Butch Herter, director of Hardware Development, Carlson Software. “The Athena RTK engine provides precise, reliable, and repeatable positions. Athena exceeds or matches the performance of all other GNSS receivers it has been tested against. We have been particularly impressed with the performance of the Athena engine, when using a long baseline or in areas where there is a limited view of the sky. Athena is a first class RTK engine.”

“We’ve been working with Hemisphere’s technology for a number of years,” states Randy Noland, vice president of business development and director of Machine Control, Carlson Software. “I’m amazed at the team they’ve brought together and how they’re radically modernizing their technology. Collaborating with the ‘new’ Hemisphere has been an eye-opening experience, and I’m excited at how their innovative technologies will positively impact our future business.”

“In the marine construction and hydrographic survey markets, time is money. We’ve seen very high system reliability and impeccable results using the Athena RTK engine, which ensures we are achieving maximum up-time,” said Harrison Steves, operations manager at Cable Arm. “As well, not being tied to a specific make of RTK base gives us flexibility with our equipment deployment.”

“We’ve found Athena to offer exceptional performance, especially their RTK fix times and maintaining RTK lock on long baselines,” said David Vaughn, CEO, Novariant. “With the latest competitive performance testing completed, Novariant is excited about adding Hemisphere’s Athena offering to the list of the Novariant-recognized certified receivers that, when combined with our precision steering solution, can assure centimeter-level steering control in the toughest environments in the world.”

CEO Statement

“Our goal is to be nothing short of the best GNSS technology partner in the industry, and a key component of that is delivering market-leading technologies tailored to our customer’s needs,” said Chuck Joseph, Hemisphere GNSS CEO and president. “To that end, we have put together a world-class team that is totally rethinking our product family, and our new Athena engine is just the first, powerful proof of our fresh approach. Watch this space!”

Availability

Before the end of this month, Athena will be included in all Hemisphere multi-frequency, RTK-capable products, such as the A325, R330, S320 and VS330. To download and install Athena, visit Hemisphere’s Software page.

Why Doesn’t My Centimeter Match Your Centimeter?
By David Doyle

Editor’s Note: This month, we introduce a column by David Doyle, one of our two new survey editors. Doyle brings to GPS World more than 40 years of experience as a geodesist and surveyor with the National Geodetic Survey — see his full bio at the end of this article. He will be joined by coeditor Dave Zilkoski, who will contribute the June column.

David Doyle

Since the mid-1980s, thousands of articles have appeared in peer reviewed journals, trade magazines and professional organization publications that describe the phenomenal capabilities of contemporary space-based positioning systems. The majority have been about various uses of the United States Global Positioning System (GPS) and increasingly include the potential for the inclusion of the Russian GLONASS, European Union Galileo and China’s BeiDou collectively referenced as Global Navigation Satellite Systems (GNSS).

Without meaning to understate the process, the ability for almost anyone, anywhere, at any time to determine a three-dimension position accurate to within a few centimeters is well established. I often comment that the systems are generally so easy to use that if you have the IQ of a squirrel you can obtain pretty good quality data. A feat that until recently was achievable only by the small community of geodesists and geodetic surveyors is now a near-trivial process for anybody who can make a modest investment in some form of positioning system device — and it’s getting better, faster, cheaper and more accurate all the time.

Our ability to collect, manage and display monumental amounts of positional data is also enhanced by the advances in Geographic Information Systems (GIS).

I have been privileged to be a part of this revolution since my initiation into the world of geodetic positioning in 1967, courtesy of the Selective Service System and the U.S. Army, and their use of geodetic triangulation combined with emerging artificial satellite systems such as SECOR (Sequential Collation of Range). These introductions to geodesy eventually led me to a position with the National Geodetic Survey and a career that spanned 40+ years.

During that time, we watched as the centuries-old method of triangulation was replaced by GPS, and as the prices of equipment plummeted with the integration of this technology into a multitude of public, private and academic disciplines — everything from geophysical sciences to weather prediction, precision agriculture, improved marine and aeronautical navigation. The list goes on and on and is well known to those who read this magazine.

So where is this going? What does the title of this article mean?

Doyle working on the Washington Monument.

If we accept, which we do, that all these things are true, then why is it that the world of sharing positional information is filled with scenarios that go something like this? “I got a cm and you got a cm, but our centimeters differ by a meter.” What this means is if these systems are so capable, then virtually all positional data integration should be a snap — everything should fit like a bespoke shirt. Unfortunately, that is often just not so.

Take the case of a decree issued by the U.S. Supreme Court in December 2014 delineating the offshore boundary between the United States and the state of California. The boundary is defined as a set of Universal Transverse Mercator (UTM) grid coordinates published to the nearest mm and referenced simultaneously to the North American Datum of 1983 (NAD 83) and the World Geodetic System 1984 (WGS 84), which the decree states are interchangeable. At the mm level, this is not true. In this area, they differ by approximately 1 m.

The decree provided no information on how these positions were derived, how accurate they really are, and who performed the computations — it certainly was not the Supreme Court. Without pointing fingers at the responsible agency, these all-too-common occurrences seems to be rampant among the many users of high-accuracy positional data, both horizontal and vertical. The crime is often the sin of omission.

The failure in many cases is a lack of knowledge on the part of many GNSS users of some of the basic principles of geodesy and geodetic surveying guidelines and providing complete metadata such as:
- what geodetic datums and potentially which realization of those datums were referenced?
- what are the units of measure?
- how accurate are the positions/heights really?
It’s important to note that the number of digits to the right of a decimal point have nothing to do with accuracy. Land surveyors are taught from their first day on the job that they are following in the footsteps of the surveyor that went before them. It is not unusual for surveyors to struggle with incomplete information from previous surveys to be able to make accurate interpretations of what the original or other previous surveyors intended — a lack of complete metadata.

Today, the massive amount of coordinate and height information being generated by thousands of surveyors, engineers and other disciplines are those footsteps — albeit digital. The multitudes of high-quality data being collected around the world is only as good as the associated information about those values.

As we rapidly approach a time when there will be vastly improved GNSS constellations and very likely cm-level positioning available to millions if not billions of people in cheap handheld devices, the issues of professional education and attention to detail are more important than they have ever been. While it would be really nice if everyone who picked up a GNSS receiver had an advanced degree in geodesy, obviously that is not only unrealistic, it’s senseless. What does need to happen is a comment that I’ve made in hundreds of seminars on these topics — those in professions and disciplines where high-accuracy coordinates are important should know enough to qualify for the Junior Geodesist Secret Decoder Ring!

There are efforts in the works at this time that may bring us a step closer to making this a reality. The American Association for Geodetic Surveying (AAGS) is working on a geodetic surveying certification initiative in collaboration with the National Society of Professional Surveyors (NSPS). This effort will be aimed at anyone who is inclined to collect, manage, distribute and/or utilize the increasing amounts of high-quality positional information.

Watch this space for more details next time.

David Doyle joined the National Geodetic Survey in 1972, and held the position of chief geodetic surveyor for 12 years before his retirement in January 2013. He was responsible for the development, technical design and management of plans and programs that enhanced the United States National Spatial Reference System. During his career with NGS, his experiences included all phases of geodetic triangulation, astronomic positioning, leveling, GPS data collection, data analysis, datum transformations, network adjustments, data publication and outreach in the form of seminars, workshops and webinars. His efforts also included extensive activities to direct and coordinate the modernization of national geodetic reference frames in countries in Africa, Central, Caribbean and South America, Eastern Europe and the Pacific.

Doyle is a past president of the American Association for Geodetic Surveying and a Fellow member of the American Congress on Surveying and Mapping. He has served on the U.S. delegation to the International Federation of Surveyors and is an active member of the District of Columbia, Maryland and Virginia professional surveyors associations. Doyle now operates Base 9 Geodetic Consulting Services.

FAA Grants Topcon UAS Exemption for Sirius

Topcon Positioning Systems has received a national exemption from the Federal Aviation Administration (FAA) that allows for operation of its unmanned aerial system (UAS) in the United States. The exemption covers the operation of the Sirius Basic and Sirius Pro for aerial data collection.

In early April, the FAA issued 30 more commercial exemptions, bringing the total to 99. That number has since grown to 235.

The Sirius Pro and Sirius Basic systems are designed to produce accurate solutions for the automated mapping of a wide range of sites — regardless of terrain — including construction sites, mines and quarries. The UAS are designed for land surveying, transmission line and pipeline inspection, and agricultural operations such as field mapping and livestock management. With the Sirius Pro model, Topcon eliminates the need for ground-control points by combining real-time kinematic (RTK) GNSS solutions with precision timing technology to provide accurate mapping results, Topcon said.

“This exemption is exciting news for the U.S. marketplace,” said Eduardo Falcon, executive vice president and general manager of the Topcon GeoPositioning Solutions Group. “It allows Topcon to be a resource for end-users and provide UAS demonstrations and training. Aerial data collection has a strong impending impact on all the industries we serve, and the possibilities for survey, construction, and agricultural applications are seemingly limitless.

“Building on the success the Sirius models have already seen in the European and Australian markets, this exemption allows Topcon to expand on that momentum in the U.S.,” Falcon said.
