A set of about 170 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs. These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0 (also read LAS-format 3.0), and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls.
The functions come with a manual in PDF format and scripts with examples. Several versions of Matlab were released during their development.

"GUI 2D-Seismic data processing software. The main functionality allows to perform surface-consistent operations based on different 2, 3 and 4-factors mathematical models. Such operations are: surface-consistent amplitude correction, surface-consistent minimum phase deconvolution and build upper layer velocity model (by factor decomposition of first break time) to determine statics shifts. Also it is easy to read/write SEG-Y files, change trace headers and trace data, work with horizons, plot seismic data and factors data-files, plot upper layer velocity. The user interface allows to use application while processing 2D seismic data."@ |

"Using latitude and longitude in calculations may lead to several problems due to the singularities at the Poles and complex behavior near the Poles, and due to the discontinuity at the Date Line (+-180 degree meridian). Instead of latitude and longitude, we represent position with an "n-vector", which is the normal vector to the Earth model (the same reference ellipsoid that is used for latitude and longitude). When using n-vector, all Earth-positions are treated equally, and there is no need to worry about singularities or discontinuities. An additional benefit with using n-vector is that many position calculations can be solved with simple vector algebra (e.g. dot product and cross product)."@ |

"A MATLAB toolbox for attitude determination with GPS multi-antenna systems -- by Zhen Dai, Stefan Knedlik, & Otmar Loffeld.
The technical paper which describes this code is published in GPS Solutions, Volume 13, Number 3, July 2009, pages 241-248, "A MATLAB toolbox for attitude determination with GPS multi-antenna systems" by Zhen Dai, Stefan Knedlik, & Otmar Loffeld Center for Sensorsystems (ZESS), University of Siegen, 57068 Siegen, Germany.
Abstract: In this paper a MATLAB toolbox for determining the attitude of a rigid platform by means of multiple non-dedicated antennas using global positioning system is presented. The programs embedded in this toolbox cover the RINEX data analysis, single point positioning, differential positioning, coordinate conversion, attitude determination, and other auxiliary functions. After forming the baselines through double-differenced (carrier phase smoothed) code observables, the attitude parameters are obtained by applying the direct attitude computation and the least squares attitude estimation. The theoretical background is summarized, and some hints regarding the software implementation are given in the paper. Moreover, improvements yielding an expanded functionality are proposed."@ |

- GPS Ephemeris Data: for GPS navigation, the position of GPS satellite is very important so the by receiving ephemeris data the position of the satellite is determined.
- GPS Errors: Three different sources of errors in GPS navigation has been investigated (Ionosphere, Troposphere and Satellite clock). Ionospheric Error model is generated base on Parkinson and the Tropospheric Error Model based on Hopfiel model.
- Simulation & GPS Toolbox: One of the targets of this work is generating Matlab GPS Toolbox and in one case study the performance of generated toolbox will be verified."@ |
