Leica releases MobileMatriX 4.0, updates GMX902 family

Leica MobileMatriX 4.0 supports the new Leica Viva GNSS series, as well as L1 and L1/L2 Post-Processing, Microsoft Windows 7 and many other improvements. It is an advanced solution for mobile GIS applications in combination with GNSS, Total Stations, Levels, Digital Cameras, and Laser Range Finders.

The GMX902 GNSS enhances the product offering by adding 50Hz data rate, triple frequency and Galileo tracking. It has been updated with high speed serial ports and even lower power consumption than before. It is ideal for monitoring vibrations and movements of a wide variety of structures including bridges, high rise buildings, dams, landslides and more.

Bentley integrates products, releases MXROAD and MXROAD Suite

Bentley Systems has integrated its civil engineering design and stormwater modeling and analysis applications to further enhance workflows and facilitate collaboration. It includes InRoads, GEOPAK, PowerCivil for North America, MXROAD, CivilStorm, StormCAD, and PondPack products.

It has also announced the immediate availability of the V8i (SELECTseries1) versions of Bentley MXROAD and MXROAD Suite – both of which provide advanced string-based modeling that enables the rapid and accurate design of all road types. The new releases also add a full-featured geospatial information management system

NovAtel Adds New IMU to its SPAN™ GNSS/INS Product Line

NovAtel Inc. recently released the latest product in its GNSS/INS SPAN product family, the IMU-LCI. It contains a Northrop Grumman sensor that provides the low noise and stability required for applications requiring precise positioning and attitude. Coordinates caught up with Mr Jason Hamilton Product Manager, SPAN group and Waypoint Products Group at NovAtel to know more about this

Would you please elaborate on the ‘low noise and stability’ of the new sensor that the IMU-LCI contains?

Closed-loop FOGs like those contained within the IMU-LCI have excellent noise and stability characteristics. The FOG random walk is quite low and the performance over temperature is also very stable. The micromechanical accelerometers are calibrated to provide stable bias over temperature. As a result, when this sensor is used in a SPAN system, the attitude accuracy is in-line with what we observe with the LN200 IMU.

Why is the IMU-LCI an ‘excellent choice for airborne and ground survey applications’?

There are multiple characteristics of the sensor that make it a good candidate for survey applications. The stable gyro and accel sensor biases limit the amount of solution drift during GNSS outage periods. The low noise gyros result in low error growth during periods of stable dynamics like flight lines. The high bandwidth of the sensors make them suitable for high data-rate applications like LiDAR and can mitigate negative navigation artifacts sometimes seen in high-vibration environments like ground mobile or helicopter applications. When combined in a tightly-coupled solution within SPAN, the product offers excellent position and orientation accuracy required by airborne applications and stable bridging of partial and full GNSS outages required for ground mapping.

Can you please name few other applications where the IMU-LCI can be used?

The IMU, as part of a NovAtel SPAN GNSS/INS system, is suitable for almost any application that requires stable position and accurate attitude output. The IMU is environmentally sealed, so it offers flexibility for a range of installations. The optional odometer input in SPAN enables improved accuracy in ground applications like ground-based LIDAR, mapping, image collection or vehicle positioning and navigation. The dual-antenna solution available when integrated with the SPANSE receiver enables marine applications like hydrographic surveying and low dynamic applications like rail monitoring.

Spirent introduces Wi-Fi Positioning Test Solution

Spirent GSS5700 Wi-Fi Positioning Access Point Simulator allows to test Wi- Fi positioning capabilities in suitably-enabled devices and chipsets. It allows real-world test scenarios, including simultaneous simulation of up to 48 Wi- Fi access points in the lab. This approach greatly reduces the need to conduct large-scale field trials while adding essential capabilities such as full user control and test repeatability. It can be combined with Spirent’s GPS and multi-GNSS Simulation Systems to test hybrid Wi-Fi and GPS/ GNSS technologies, with the unique ability to simulate motion of a mobile device through environments where both sets of signals are present.

Autodesk Topobase 2011 Products

Autodesk released its Topobase 2011 products and its MapGuide Enterprise 2011 software, new tools that help customers manage infrastructure assets more effectively and plan for the future. With these products, infrastructure professionals can get a broader understanding of the location and status of their assets and more easily share information over the web.

New 3D Machine Control Software

Carlson’s 3D machine control software, Carlson Grade, has many new and enhanced tools, which can be used with a wide variety of heavy machines and is designed to be a flexible and open 3D machine control system. Compatible with most heavy equipment, it support includes dozers, drills, loaders, scrapers, excavators, bucket wheel excavators, compactors, shovels, graders, and foreman trucks.

Smallest Dual Frequency GPS receiver

NovAtel OEMV® receiver OEMV- 1DF™ is only 46mm x 71mm x 13mm in size, it is the industry’s smallest dual frequency GPS receiver to provide centimetre level, high performance RTK positioning. Weighing only 21.5 grams and consuming less than 1.1 Watts, it is ideal for size constrained applications.
