GNSS receiver for transmission corridor survey

The Spectra Precision SP60 GNSS receiver has been selected to perform survey work for construction of a new 450 km electric power transmission corridor. Connecting Mauritania’s two largest cities, the capital Nouakchott and to the south Nouadhibou, the 225/90 kV transmission line runs parallel with the Atlantic Ocean as it traverses the Sahara Desert.  The […]

Why I love radio – a personal history of the medium

I grew up in a home filled with music. My parents often had the radio on for most of the day on weekends. We listened to music, news programmes, radio plays, and interviews of important people. I recall the family sitting around the radio listening to “Sunday’s world at 1 PM” catching up with what […]

New UAV lidar system unveiled

The Surveyor Ultra is the new UAV lidar system from YellowScan, integrating the Velodyne VLP-32C scanner and the Applanix APX-15 IMU. With its high-density (600 000 points per second), the system is well-suited to high speed UAVs and long-range needs, with a maximum range of 100 m. Its light weight (1,7 kg) makes it easy […]

Lidar enables discovery of Mayan ruins

Teledyne Optech’s Titan sensor was used by the University of Houston’s National Center for Airborne Laser Mapping (NCALM) to reveal extensive Mayan ruins in Guatemala. Lidar technology was able to identify hundreds of previously unknown structures, including raised highways, and complex irrigation and terracing systems. After the collapse of the Mayan civilisation, their cities and […]

Wind-sensing satellite undergoes final checks

The European Space Agency’s (ESA) wind sensing spacecraft, Aeolus, will be the first satellite capable of performing global wind-component-profile observation on a daily basis in near real-time. Aeolus has left Liège in Belgium having successfully completed extensive thermal and functional performance testing. It will now undergo final checks at InteSpace test centre in France, before […]

Lidar system for mapping complex terrain

TerrainMapper is Leica Geosystems’ next generation linear mode lidar system. As part of the RealTerrain airborne lidar mapping solution, the sensor is supported by the HxMap unified multi-sensor post-processing workflow. The mapping solution enables users to increase point accuracy, deliver even point density across the swath, and accommodates more efficient flight planning in complex terrain […]
