The Deflection of the Vertical (DOV)as one basic research topic in geodesy and geophysics can characterize thedirection of gravity vector
and provide one tight local tie among space geodetic techniques (Shen et al.
If measurements from sensor array (accelerometer, gyroscope and magnetometer) are available, then gravity vector
g = [[[g.
Matrix w is raw data from the accelerometer collected at 6 stationary positions (when device lays on each side of the device and normalized gravity vector
is zero in two axis).
The activity shall lead to the development of a laboratory breadboard which demonstrates functional performance as well as its performance under EAA--gravity conditions the latter may be tested by relative simple means such as reversing the direction of the gravity vector
In this section it is presented a Computational Fluid Dynamics (CFD) modeling for a qualitative analysis intending to show the main influence of the gravity vector
in quantifying initial efficiency collection by settling mechanism.
A combination of modeling of gravity vector
and vertical deflections based on GPS/leveling surveys seems to be important for the estimation of the external accuracy of quasigeoid models.
gamma] is the gravity vector
and m is the mass of body.
If the Sagnac light loop area has a unit vector that is perpendicular to the acceleration of gravity vector
, then the motion of the interferometer will exhibit a red-shift that will be given by:
Uncertainties associated with transducer mounting in the force machine, such as the placement of the point of force application on the transducer or the alignment of the vertical gravity vector
with the load cell axis, are discussed in Sec.
Finally, variations of the gravity vector
are studied by absolute gravity measurements made in Spain.
An exclusive hip tracker underneath the platform follows the athlete back and forth on the platform and helps maintain a true center of the earth gravity vector
One is installed on the master axle beam for gravity vector
reference, and one is installed on each of the two axle swing arms for reference to the axle while the trailer is in motion.
