Global navigation satellite systems such as the Global Positioning System (GPS) is one of
the most important sensors for movement analysis. GPS is widely used to record the …

The application of low-cost L1 GPS receivers integrated with micro-electro-mechanical
system (MEMS) inertial measurement units (IMU) allows the continuous observation of …

This dissertation describes improvements made to a system for airborne map** of the
gravity field of the Earth. The research is carried out using an airborne gravity system that is …

This research scrutinizes the method of INS/DGPS integration to provide the parameters of
exterior orientation needed for direct georeferencing of airborne imagery more reliably and …

Satellite velocity determination using the broadcast ephemeris is discussed and it is pointed
out that the conventional rotation matrix method involves a complicated process of …

Carrier-phase-smoothed code (CPSC), ie, smoothing of the code using carrier phases, has
widely been used to reduce the code noise in GNSS applications. However, the efficiency of …

To date, operational airborne gravity results have been obtained using either a damped two-
axis stable platform gravimeter system such as the LaCoste and Romberg (LCR) S-model …

It is well known that accurate aerial position and attitude control is beneficial for image
orientation in airborne photogrammetry. The aerial control is traditionally obtained by …

Difference methods have been routinely used to compute velocity and acceleration from
precise positioning with global navigation satellite systems (GNSS). A low sampling rate …

The determination of velocity and acceleration from GPS measurements is very important for
many dynamic applications, but also for airborne gravimetry and geophysics, as long as we …
