Topcon Adds Mapping System

Topcon Adds Mapping System

Topcon Positioning Systems (TPS), Livermore, California, has announced the addition of the IP-S2 HD Mapping System to its line of mobile mapping solutions.

The IP-S2 HD is a vehicle-mounted surveying and mapping system featuring a high-definition LiDAR scanner from Velodyne Lidar, Inc. The system incorporates high-precision GNSS receivers, an inertial measurement unit, vehicle wheel encoder, 360-degree digital cameras and Velodyne’s HDL-64E S2.2 LiDAR scanner.

GNSS Simulation: A User’s Guide to the Galaxy

GNSS Simulation: A User’s Guide to the Galaxy

FIGURE 1: Screenshot of RF simulation software showing GPS + GLONASS + Galileo constellations

In the first article in this series (Inside GNSS, July/August, 2010) we looked at the range of tasks that require GNSS signal simulation during design, manufacturing, certification, and maintenance of GNSS equipment. The second installment (Inside GNSS, September, 2010) described a range of simulation solutions.

In this final article, we try to find a simulation solution that best suits a particular task.

A Search for Spectrum: GNSS Signals in S-Band, Part II

A Search for Spectrum: GNSS Signals in S-Band, Part II

GNSS utilization of the S-band portion of the radio spectrum provides some challenges to designers of both GNSS navigation signals as well as signals used by other services, in terms of interference avoidance and signal power.

An important existing user of S-band spectrum is the Globalstar communications satellite system. The voice and data services provided by Globalstar employ the 2483.5–2500 MHz band for its satellite downlink communications to user terminals. Additionally, these satellites use multi-beam antennas to enable frequency reuse.

2010 UN-IAF Workshop: GNSS Applications for Human Benefit and Development

Prague Congress Centre

The workshop on GNSS Applications for Human Benefit and Development is sponsored by the United Nations Office for Outer Space Affairs and the International Astronautical Federation (IAF).

It is the 20th joint UN-IAF workshop and will be held at the Prague Congress Centre (PCC) in Prague, Czech Republic just before the 61st International Astronautical Congress that runs from September 27-October 1.  Participants at either event are welcome at the other.

Oregon: More GPS Product Design and GNSS-related Industry Here Than You May Think

by Glen Gibbons

Few would mistake Oregon for the beating heart of GNSS. Still,  for a medium-sized U.S. metro area in the Pacific Northwest, Portland  and Oregon’s I-5 corridor has enough relevant involvement with the industry to justify hosting the Institute of Navigation’s 2010 GNSS conference and exhibition.

Oregon has FLIR Systems, Cloud Cap Technology, TriQuint, Intel, Garmin and Inside GNSS magazine.

When GNSS Goes Blind

When GNSS Goes Blind

A completely GPS-based navigation solution is generally not feasible in GNSS signal–challenged environments such as urban canyons. However, even in these difficult environments a partial set of GPS signal measurements may still be available. For instance, one or two satellites are generally still visible even in dense urban canyons.
