This is not directly about laser scanning, but for many applications GPS (or GNSS) plays an important role in the overall workflow. It seems that a group of researchers at the University of Texas Austin have figured out a way to obtain centimeter level accuracy with a low cost modification to a cell phone.
The UT Austin team has created software over the past six years that uses sophisticated signal processing techniques to process the data from a smartphone GPS antenna and reduce the effect of multipath and other errors. The software currently runs on a separate computer from the smartphone, but one of the engineers says it would eventually run on the phone’s internal processor.
