A New Technique for INS/GNSS Attitude and Parameter Estimation Using Online Optimization [PDF]
IEEE Trans. on Signal Processing, 62 (10), 2642 - 2655, 2014, 2014 Integration of inertial navigation system (INS) and global navigation satellite system (GNSS) is usually implemented in engineering applications by way of Kalman-like filtering. This form of INS/GNSS integration is prone to attitude initialization failure, especially when the host vehicle is moving freely.

A Multimethod Investigation of the Lake Agnes Rock Glacier, Colorado, USA
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Rock glaciers are important headwater landforms that play a key role in alpine hydrology. North American rock glaciers are estimated to contain the third largest water volume equivalent globally, and over 3800 rock glaciers have been mapped in Colorado alone. However, these features are often overlooked in alpine water budgets.
