NASA helps maintain International Terrestrial Reference Frame with GNSS

February 29, 2016By
Sites around the world (yellow dots) contributed data and serve as “landmarks along a trail” for the newest update to a global standard called the International Terrestrial Reference Frame. Each site conducts precision measurements using at least 1 and up to 4 geodetic techniques.

News courtesy of NASA / Goddard Space Flight Center The surface of Earth is constantly being reshaped by earthquakes, volcanic eruptions, landslides, floods, changes in sea levels and ice sheets and other processes. Since some of these changes amount to only millimeters per year, scientists must make very precise measurements of the landscape and ocean in space and time in... read more

It happened in the blink of an eye. Less than a blink. Far less, actually. Slightly more than one one-thousandth of an eye blink, according to calculations. In that amount of time, one of your eyelashes traverses 10 micrometers on its journey toward your lower eyelid. And yet it was long enough to throw computers and communications systems around the... read more

Expert Opinions: Optimum number of GNSS signals for PNT device

February 22, 2016By

Q: What is the optimum number of GNSS signals to include/process in a consumer-grade PNT device? A: The cost for including additional silicon to a receiver for processing more signals is low, thanks to multiplexing hardware and high clock speeds. Having more satellite measurements allows the receiver to be selective about which ones it actually uses for PVT calculations, so... read more

Antennas: The unsung heroes of the GNSS industry

February 22, 2016By

By Tracy Cozzens Managing Editor Antennas. When I was a kid, antennas meant the pair of rabbit ears sitting on top of the family TV set. We had to constantly adjust the angles to get the best reception, using aluminum foil to improve the signal. Wow, how things have changed. Today, consumer users of smartphones, Fitbits, smartwatches, tablets and a... read more
