Top-level updates from Munich summit on four GNSS

March 22, 2017By

Here’s a panorama in broad strokes across the range of GNSSs, garnered from top system spokespersons at the Munich Satellite Navigation Summit. It’s been several years since breaking news was aired at this annual late winter/early spring event, but it’s always good for a wide-ranging update, recalibrating levels, so to speak. GPS. With 31 operational satellites (24 is baseline) and... read more

Expert Opinions: Considerations for simulating GNSS signals for UAVs

March 22, 2017By

Q: What are the key factors to consider when simulating GNSS signals for UAVs?   A: For UAV simulation, a record-and-playback system is obviously less applicable, as the user is more interested in defining system operability within a range of parameters rather than in any generalized case. A high-dynamic user performance is required, but users should look at a simulator’s... read more

The state of the UAS/UAV industry

March 15, 2017By

Assessing the health of an entire industry is not an easy task, but talking with industry leaders and looking for examples of growth and investment can help. Our “State of the UAS/UAV Industry” inquiries have lead to discussions with General Atomics, Association for Unmanned Vehicle Systems International (AUVSI), Aeryon Labs and SensoFusion. SensoFusion might be a little well less known... read more

Respect the facts: March for Science

March 14, 2017By

In life, few things are certain. In family, love and friendship, fewer. Add more people — workplace, groups, associations, government, society, nations, war — and the complications multiply, the certainties become more scarce. Some things, however, remain fixed, and true. We call them facts. They are not subject to denial or claims of fakery. They can sometimes be distorted, or... read more

GNSS plays prominent role at Mobile World Congress

March 5, 2017By

Global navigation satellite system (GNSS) technology found its way into products ranging from autonomous vehicles to wearables at this year’s Mobile World Congress in Barcelona, Spain. One company says it is tailoring a GNSS receiver chip to meet the demands of mobile devices that require high levels of speed and position accuracy. Thalwil, Switzerland-based u-blox said its new low-power UBX-M8230-CT GNSS... read more

GNSS and the Surveyor: Take Me to School

March 1, 2017By

The adaptation of GPS for civilian use is the single greatest step taken by  the land surveyor, more specifically the advance to  real-time kinematic networks. Now unmanned aerial vehicles enable data collection in places thought impossible previously, and laser/LiDAR scanners are on the horizon as the next game-changer. But how did we get here? An understanding of our history can... read more

Recommendations: RTCM on BeiDou use, DHS on critical timing receivers

February 24, 2017By

Two documents of interest and importance to GNSS designers and manufacturers have been published, one from the Radio Technical Commission for Maritime Services (RTCM) and one from the U.S. Department of Homeland Security (DHS). The latter document is the subject of a news story concerning receivers used in critical infrastructure, with an emphasis on timing receivers. It provides owners, operators, researchers,... read more
