  The April 25 magnitude 7.8 earthquake in Nepal created waves of energy that penetrated into Earth’s upper atmosphere in the vicinity of Nepal, disturbing the distribution of electrons in the ionosphere. These disturbances were... read more

Why Doesn’t My Centimeter Match Your Centimeter?

The world of sharing positional information is filled with scenarios like “I got a cm and you got a cm, but our centimeters differ by a meter.” If our modern positioning systems are so capable, then virtually all positional data integration should be a snap. Unfortunately, that is often just not so. The failure in many cases is a lack of knowledge on the part of many GNSS users of basic principles of geodesy and geodetic surveying guidelines and providing complete metadata. read more

Innovation: Robustness to Faults for a UAV

Integrated Navigation Systems Using Parallel Filtering
The authors look at the development of a robust navigation system employing a GNSS receiver, accelerometers, gyroscopes, magnetometers, an airspeed device and dead reckoning to supply a blended navigation solution to a flight control system on a small, unmanned aerial vehicle. read more
