Horizontal dimensional accuracy prediction of selective laser melting
Materials & Design, 2018 A theoretical model has been proposed to predict the horizontal dimensional accuracy of selective laser melting (SLM) in this paper. It is found that the horizontal dimensional deviation of SLM consists of two parts. The first part is related to the mode

ASSESSMENT OF 3D POSITIONAL ACCURACY OF GEODETIC OBSERVATIONS FROM SINGLE CORS [PDF]
Geological Behavior, 2022 Geodetic observations for both vertical and horizontal control networks cannot be compromised for any reason in accuracy and precision in the field of geomatics. Due to the error-prone nature of survey measurements, standards are established to allow for

How a GNSS Receiver Is Held May Affect Static Horizontal Position Accuracy. [PDF]
PLoS ONE, 2015 The static horizontal position accuracy of a mapping-grade GNSS receiver was tested in two forest types over two seasons, and subsequently was tested in one forest type against open sky conditions in the winter season. The main objective was to determine
