L1/L2 GLONASS Simulation System

Spirent Communications (UK) has announced the addition of GLONASS L2 test capability to its new GSS8000 simulation system which already supports GLONASS L1 simulation. This establishes the GSS8000 as the industry's first simulation system to support GLONASS L1 and L2 commercial signals. With this launch, GLONASS L1/L2 capability will be available both in a stand-alone system and also in combination with GPS and/or Galileo signals.   Simulation of GLONASS and other GNSS signals is the best way of testing receivers, systems and application performance. Only laboratory simulation can ensure controlled repeatable testing that explores both nominal and off-design conditions. By... (read more)

Building a Global 3D Routing Map

Using Mobile Mapping to Collect Trillions of Points around the World
Mapping company HERE, co-owned by German automotive companies Audi, BMW, and Daimler, uses a fleet of more than 200 cars to collect dense point cloud data about roads around the world. The data from these mobile mapping vehicles is processed to secure privacy and produce detailed routing maps. This data is the input for various applications, ranging from traditional car navigation to analysis of the steepness of ramps. The most compelling application, however, is the application of this data to enable self-driving cars. Digital street maps are essential to car navigation and visualisation of online mapping products. Traditionally, such maps... (read more)

GPS L-Band Threatened

The L-band, in which the GPS/GNSS L-1 signal also resides, might soon be overcrowded in several US densely populated areas. LightSquared (a Mobile-satellite service operater (MSS) and Ancillary Terrestrial Component (ATC) license holder) is seeking a reallocation of its L-band from a space service to primarily a terrestrial wireless service. Lightsquared would like to provide primarily voice and data broadband services on the L-band frequencies they currently hold a license for. This change in usage of the bandwidth together with a densely populated powerful (1500 W) transmitter network could mean that the GPS/GNSS L-1 signals are negatively influenced. This could...

Global Entrepreneurs

Four years ago I predicted in one of the columns of this journal (see Product Survey October 2002) that China would become a significant player as a manufacturer of High-end Total Stations. ‘Competition may come from an unexpected part of the world,’ I wrote, ‘and that is China.’ Back then, in 2002, the total-station industry in China was mainly focused on construction-site instruments. However, as a result of the rapid adoption of modern technology, today no less than five Chinese firms have entered the top segment of the total-station market, including South, from Guangzhou, FOIF from Suzhou, Phenix from Shanghai...

Global Change

  Everything evolves. Daily newspapers become blogs on the internet. Hotel room keys become magnetic cards. Nowadays you can pay your parking ticket using your mobile phone. And so land surveyors are becoming geomaticians...   If they don't want to become the local surveyor working within a mile of the church spire, next-generation geomaticians must broaden their horizon. They need to combine measuring techniques with CAD, but also with geographical information systems and databases.   New mapping methods bring in such huge volumes of data that you have to reflect on how to store, catalogue and manipulate this information.  ...
