Implementing NGS Draft Guidelines for GPS-Derived Orthometric Heights
The need to determine accurate heights relative to the North American Vertical Datum of 1988 (NAVD 88) is more prevalent today than ever before. Projects are no longer isolated unto themselves, or designed in a box. Due to global and regional issues such as the environment, and municipal planning, the need to represent the topographic features of the earth accurately in three dimensions is of p...
متن کاملA Small Printed Quadrifilar Helical Antenna for BGAN/GPS Applications
This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the fou...

متن کاملEffect of increasing number of neurons using artificial neural network to estimate geoid heights
Nowadays the GPS measurements are one of the most frequently used technique in geodesy. With this technique ellipsoidal height can be reckoned. However in the engineering practice orthometric heights (height above sea level) are used. The orthometric heights are determined by levelling. Transforming the GPS-derived ellipsoidal heights to orthometric heights it is important to know the distance ...
