ITEM 1) NEW
VERSION 4 OF GPS TOOLBOX BY LARRY LUPASH
What is new in version 4 of GPS Software Toolbox
Here is the list of main upgrades and changes:
- a complete RINEX 2 data processing, including the position
determination
- GPS receiver specialized functions, including pseudorange and
carrier phase analysis, covariance analysis for a 5-state and
8-state GPS receiver models, pseudorange smoothing based on
carrier phase data
- reorganization of RAIM/FDE function in basic and advanced
sections and the inclusion of HPL/VPL and HEL/VEL determination
and related functions
- additional functions in many prior subsections, e.g. satellite
velocity computation, SEM almanac processing
- a complete directory containing test examples (softcopy) for
all main programs
- an expanded section containing more relevant GPS examples.
GPS Toolbox by L3NAV is a library of MATLAB m-file modules and
programs used for the implementation of GPS applications. It
enables the user to simulate a specific GPS application quickly
and easily without the need to code and test the basic GPS
algorithms.
The MATLAB GPS Toolbox contains numerous main programs which can
be modified to fit specific application needs. Once the model of
the application is derived or selected, the practitioner can use
the software library to implement and test the validity of the
proposed GPS application.
All of the more than 200 m-files are compatible with MATLAB 5.0
and higher, and most are also compatible with previous versions
and Student Editions of MATLAB.
There are more than 31 fully explained examples (more than 80
pages) with input and output data and plots. Overall, the User's
Guide and Reference Manual has more than 200 pages. The source
code is royalty free. The user can incorporate this software
into applications, but is not permitted to resell the software
"as is" or with changes.
Promotional pricing is available on the new version 4.01 until
the end of March.
