Abstract: RTKLIB is an open source program package for RTK-GPS developed by the authors. RTKLIB is a compact and portable program library written in C to provide a standard platform for RTK-GPS applications. The library implements fundamental navigation functions

The neglected receiver
free download

Knowledge sharing has become a legitimate and important organizational activity, and over the last five years companies have been inventing many ways to make knowledge sharing happen, eg, collecting lessons learned, building yellow pages to help employees find Abstruct-In code division multiple access (CDMA) mobile radio systems, both intersymbol interference and multiple access interference arise which can be combated by using either elaborate optimum or favorable suboptimum joint detection (JD) techniques. Furthermore,

International reports: Technical directives for standardization of GPS time receiver software
free download

The observation, using the common-view method, of satellites of the Global Positioning System (GPS), is one of the most precise and accurate methods for time comparison between remote clocks on the Earth or in its close vicinity. It has already been shown that

Iterative receiver design
free download

In early 2002, I was absent-mindedly surfing the Internet, vaguely looking for a tutorial on turbo codes. My PhD advisor at Ghent University, Marc Moeneclaey, thought it wise for his new students to become familiar with these powerful error-correcting codes. Although I

ABSTRACT DELSOLS is a revised and updated version of the DELSOL2 computer program (SAND81-8237) for calculating collector field performance and layout and optimal system design for solar thermal central receiver plants. The code consists of a detailed model of the

An intuitive approach to receiver operating characteristic curve analysis
free download

Meaningful comparison of diagnostic imaging tests inevitably requires expression of observer performance. The most commonly used measures of observer performance sensitivity, specificity, and percentage accuracy fail to take account of variability of the

Experimental investigation of natural convection heat loss from a model solar concentrator cavity receiver
free download

Natural convection heat loss inevitably occurs in cavity-type receivers in high concentrating solar dishes, downward focusing systems and solar towers. In most applications, it can contribute a significant fraction of total energy loss, and hence it is an important determining

Performance of the directly-irradiated annular pressurized receiver (DIAPR) operating at 20 bar and 1,200 C
