  • Topcon Announces MR-1 Precise Heading Solution

    Topcon Positioning Systems has released the MR-1 Heading System, an OEM GNSS solution for high-performance positioning and heading.

    Using the MR-1 receiver and Topcon’s MG-A8 antenna, the system provides “centimeter-accurate RTK positioning and better than 1/10 of a degree heading accuracy in challenging environments,” said Doug Langen, TPS GNSS product manager. “The rugged MR-1 receiver is water and dustproof and operates at a robust operational temperature range of -40°C to 75°C.”

    When combined with Topcon’s Quartz Lock Loop technology, the MR-1 offers continuous operation during “extreme vibration and shock, typical of intense dynamic environments,” he said.

    The MG-A8 antenna of the MR-1 Heading System is designed for moving platforms and provides multipath rejection. It also offers increased resistance to near-band interference from satellite communications systems commonly found in marine applications.

  • Two Active GLONASS Satellites Could Cause Users Difficulties

    On day 53 (February 22) around 09:15 GPS Time, GLONASS 743 began transmitting on frequency channel 6 using almanac slot 8 (R08). It should replace GLONASS 701K (801) transmitting on frequency channel -5, previously using almanac slot 8. However, GLONASS 701K was not immediately switched off and/or did not switch slot numbers and continued to transmit on frequency channel -5 for several days, continuously identifying itself as a slot 8 satellite.

    While most receivers were just tracking GLONASS 743, some tracked both GLONASS 743 and 701K. While 701K was not in the broadcast almanac, it was transmitting ephemeris records identifying itself as a satellite in slot 8. The net result was that RINEX observation files from certain stations had a mixture of GLONASS 743 and 701K data, with no indication of which satellite was which. Of course, one could use expected Doppler shift and/or code/carrier rate of change to figure out which data records correspond to which satellite.

    Furthermore, the GLONASS navigation files from certain stations contained a mixture of ephemeris records from GLONASS 743 and 701K. For day 54, for example, GLONASS navigation files for 146 (non-MGEX) stations were available at CDDIS. A number of these did not contain any R08 entries, presumably because the corresponding receivers were set to not track unhealthy satellites. Some of the files contained R08 ephemeris records from earlier dates. These were ignored.

    This left 82 files containing either GLONASS 701K and/or 743 ephemeris records for day 54. These files were parsed to determine, for each file, for which times ephemeris records were available for which satellites. The results are summarized in the following plot (PDF available):

    glonass_slot8_in_nav_files_054_2013
    Results of Glonass

    The station numbers correspond to those in this table.

    The navigation files from 29 stations contain both GLONASS 701K and 743 records. It seems that JAVAD GNSS and Topcon receivers were primarily affected.

    Note that the CDDIS brdc***0.13g files on affected days have a mixture of GLONASS 743 and 701K ephemeris records, but at any one epoch, only one satellite is represented.

    Files from days 53 through 56 are affected.

    It appears that GLONASS 701K stopped identifying itself as a slot 8 satellite after about 15:15 GPS Time on day 56 and was not subsequently tracked by any station supplying data files to CDDIS.

  • New Organization Advocates for GPS Industry

    A new group, the GPS Innovation Alliance, has formed and announced itself as the voice of the U.S. GPS industry and community of users, to “support the ever-increasing importance of GPS” in the U.S. capital, Washington, D.C.  The organization subsumes and replaces both the U.S. GPS Industry Council, an entity of longstanding, and the Coalition to Save Our GPS, which arose in March 2011 in response to a Federal Communications Commission (FCC) conditional waiver granted to LightSquared.

    The alliance appears to reflect a desire on the part of some industry members to take a more aggressive approach inside the Washington Beltway, a sign, it would seem, of the political times. Some of those involved spoke informally of a desire to take advantage of contacts made on Capitol Hill and in the media during the highly visible LightSquared combat, fought in the glare of media attention heretofore unknown in industry circles.

    Members of the Alliance are drawn from a variety of fields and businesses reliant on GPS, as well as leading manufacturers of GPS equipment. The former group includes, aviation, agriculture, construction, transportation, first responders, and surveying and mapping, and consumer organizations representing users of GPS for boating and other outdoor activities, and in automobiles, smartphones, and tablets.

    Joining John Deere, Garmin, and Trimble — three lead drivers of the Coalition effort at the FCC — are NovAtel Inc. and Topcon Positioning Systems. All five were previously long-time members of the USGIC, and they appear as founding members of the alliance at www.gpsalliance.org.

    Affiliate members listed on the website include the Association of Equipment Manufacturers, General Aviation Manufacturers Association, National Association of Manufacturers, Association for Unmanned Aerial Vehicles International, and Boat Owners Association of the United States.

    The alliance plans to build on “the proud heritage and extensive expertise of the United States GPS Industry Council (USGIC), which was formed in 1991 to promote broader commercial applications of GPS and to expand global markets while assisting in safeguarding the technology’s military advantages. The council has a long history of highly effective advocacy on behalf of the GPS industry, as well as serving as a trusted source of objective information for policy makers, the media and the public both in the U.S. and around the world.” The alliance website gives a longer statement about the history and record of the USGIC, highlighting its role in international negotiations.

    Michael Swiek, executive director of the USGIC, has transitioned to become the executive director, executive branch and international, of the Innovation Alliance. In addition to working closely with leading offices of executive branch departments of the U.S. government, he will continue well-established dialogs with governmental, private sector and academic entities in areas critical to GPS and satellite navigation among key players in Europe, Japan, Russia, Korea, China, and elsewhere.

    Heather Hennessey, a principal of Innovative Federal Strategies LLC, a “comprehensive government relations firm,” has taken the position of executive director, legislative, at the alliance. Hennessey has seven years of service in the House of Representatives, including two years as chief of staff for Congressman Jack Kingston of Georgia.

    An active voice in alliance representations on Capitol Hill will presumably be that of Jim Kirkland, vice president and general counsel for Trimble. Kirkland was the most prominent spokesperson for the coalition during the LightSquared battle, which appears to be either over or nearly so. “The alliance is committed to ensuring constructive, robust dialog between GPS users, manufacturers and policy makers on critical policy issues affecting GPS,” Kirkland said, “a commitment Trimble is pleased to be a part of as the industry continues to innovate and modernize.”

    The alliance mission statement cites the importance of GPS to global economy and infrastructure; vows to aid further GPS innovation, creativity and entrepreneurship; and to protect, promote and enhance the use of GPS.

    The GPS Innovation Alliance officially launched on February 13 with a reception on Capitol Hill, a traditional lobbying tactic that previous efforts had perhaps not envisioned.  The organization has also hired a public relations firm, Prism Public Affairs, and commissioned a logo.

    Topcon HiPer SR and Pocket 3D in the field.

    With the introduction of a new version of Pocket 3D software for its HiPer SR GNSS receiver, Topcon Positioning Systems is expanding the delivery of high-accuracy 3D positioning technology to contractors needing a low-cost, one-man layout and measurement system.

    Pocket 3D is powerful, easy-to-use data collection and control software for grade checking and other measurement applications on a job site. Version 10.0.2 makes it fully functional with the HiPer SR receiver, introduced in August.

    The new receiver is not only “perfect for contractors, but also for other non-traditional GNSS users such as landscape architects, law enforcement forensics projects or any others requiring high-accuracy 3D positioning,” said Tony Vanneman, Topcon construction products marketing manager.

    Its field-rugged and fully-integrated design delivers a 1,000-foot working radius through Topcon’s new LongLink technology. “This innovative wireless data link was developed specifically for the HiPer SR, and provides reliable and interference-free base-to-rover communications that don’t require an FCC license to operate,” Vanneman said.

    “We took the best signal tracking technologies and packaged them in a small, energy-efficient design,” he said.  “Anyone looking for a rugged, easy-to-use, low-cost 3D GPS system will find what they need in the HiPer SR.”

    Additional key features of the HiPer SR include:

    • Shock-resistant magnesium alloy housing – allowing the HiPer SR to take a 6 ft. (2m) pole drop onto concrete;
    • Weighs 1.8 pounds (0.8kg);
    • 226-channel Vanguard technology, featuring Universal Tracking Channel technology, supports all satellite constellations;
    • Fence antenna technology;
    • Quartz lock loop technology for superior GNSS tracking in high-vibration environments, such as on a four wheeler;
    • Capable of simultaneous LongLink operation with multiple rovers;
    • Sealed battery pack provides more than 15 hours of operation.
  • HiPer V Featuring Vanguard Technology Offered by Topcon

    HiPer V Featuring Vanguard Technology Offered by Topcon

    Topcon has introduced the HiPer V receiver, which features Topcon’s Vanguard technology. The HiPer V provides users with the choice of GPS and GLONASS signals (as well as Galileo when operationally available), and also includes a variety of choices of internal radio, cellular and Bluetooth communication options and what Topcon calls a state-of-the-art power supply.

    The core of the HiPer V is the new Vanguard GNSS technology, according to Ewout Korpershoek, Topcon senior vice president and chief marketing officer. With its 226 channels and Universal Tracking, the Vanguard chipset is future proof, as it will track signals from all available and currently planned GPS, GLONASS and Galileo satellites.

    “Topcon’s Universal Tracking provides a whole new definition of ‘channel technology.’ There is nothing available like it. Universal Tracking allows a single receiver channel to ‘automatically’ select and track any satellite signal,” Korpershoek said. “Because our channels are not pre-programmed to receive only one specific signal or a type of signal, Topcon users will always receive the maximum number of signals at any given time. In addition, Topcon’s Universal Tracking will automatically weigh the best combination of available signals based on health, geometry and application, providing unmatched accuracy, speed of initialization and fixing. HiPer V will work at places where other receivers will not, at highest accuracy, and with greatest ease of use.”

    Other features include the rugged, durable magnesium alloy housing, the choice of communication options, “and longest life rechargeable battery while maintaining the lightest weight in its class,” Korpershoek said.
