Topcon Launches Two UAS Mapping Systems

Topcon Launches Two UAS Mapping Systems

Topcon Positioning Group has released two unmanned aerial systems (UAS) for mapping — the Sirius Pro and Sirius Basic.  Both 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, and for use in land surveying, power line and pipeline inspection as well as precision agriculture field mapping.

Falling Prices Will Spur Innovation, Competition in High-Precision GNSS Market

The high-precision GNSS industry should expect to see industry consolidation and a scramble for new markets and innovations as prices for high-end chips and modules continue to slide, experts told attendees at a ION GNSS+ panel discussion in Tampa, Florida, last week (September 11, 2014).

The falling prices could strain R&D budgets, they noted, but could also create opportunity as high-end receivers come within reach of emerging industries like self-driving cars, unmanned aerial vehicles, and are even incorporated into consumer products.

Europe’s UAV Experience

To say that the European unmanned aerial vehicle (UAV) industry has drawn a crowd may be understating things. According to Paris-based UAV International, the non-profit association representing European UAV manufacturers, the European Union (EU) counts more than 1,000 “approved and authorized” civil UAV operators within its borders. Others put that number at closer to 1,400.

GNSS Position Estimates

Q: How do measurement errors propagate into GNSS position estimates?

A: Not surprisingly, GNSS positioning accuracy is largely dependent on the level of measurement errors induced by orbital inaccuracies, atmospheric effects, multipath, and noise. This article discusses how, specifically, these errors manifest as position errors.

Environmental Sensing

Environmental Sensing

In the past 20 years GPS has simultaneously revolutionized both our modern infrastructure (by providing real-time navigation, mapping, and timing support) and our geodetic/surveying capabilities (by providing millimeter/centimeter-level positioning). At this point, most of the GNSS innovations we expect to see in the next decade will come from calculating positions more accurately and faster, while expanding from GPS to use of all available GNSS signals.

Communications Act Rewrite Could Adversely Affect GPS Community

Two powerful lawmakers are weighing rewriting the rules for the way frequencies are allocated as part of an overhaul of the nation’s telecommunications laws. The effort, which is likely to see legislation drafted next year, is considering options such as flexible licensing and receiver standards that could directly affect the GPS community.

FAA Seeks Comment on Groundbreaking UAS Application, Model Aircraft Rules

Federal aviation officials appear to be moving quickly to defuse mounting pressure for the commercial use of unmanned aircraft, clarifying their authority over such aircraft and starting the public process for licensing small firms for limited operations.

The Federal Aviation Administration (FAA) has taken a tough stance in its interpretation of the legal uses for model aircraft published on June 23 in the Federal Register. The issue surged into the national spotlight when the agency failed to win a legal challenge over its authority to regulate such devices.
