 SATNAV Toolbox
Satellite Navigation Toolbox for MATLAB by GPSoft.
GPSoft has applied the power of MATLAB to
GNSS. The SatNav Toolbox is a unique collection of M-files which allows for total system
emulation.
The SatNav Toolbox simulates not
only satellites and receivers, but also the propagation channels. Error sources such as
thermal noise, multipath, aospheric delays and Selective Availability are modeled as an
integral part of pseudorange (i.e., code- phase) and integrated Doppler (i.e.,
carrier-phase) emulation. Furthermore, the errors are generated such that the proper
temporal and spatial decorrelation effects are observed in the measurements. This allows
for realistic modeling of both code-phase DGPS and carrier phase DGPS (i.e., kinematic) in
addition to the usual stand-alone positioning algorithms.
Version 3 of the
SatNav Toolbox adds RINEX (receiver independent exchange format) data
file processing to its simulation and analysis power. In addition, many
of the demo programs have been updated to include simulation Galileo,
WAAS and EGNOS.
All routines are provided as M-files
thus allowing the user full access to the code and the ability to modify to suit
one’s needs. Full documentation is provided through an extensive user manual as well
as through the MATLAB HELP command. The SatNav Toolbox is easy to use (ideal for
educational purposes, yet powerful for the seasoned GNSS engineer). In addition to the
product itself, GPSoft provides to all registered users, two years of technical support
at no additional cost.
The SATNAV Toolbox is compatible with MATLAB 6.0
An version upgrade
2.0 to 3.0 is
available for currently registered users for $495.00. Upgrade includes updated software
and an all new user manual. Call Navtech for details.

NEW
in v 3.0! Real data file processing through RINEX
support
Emulation of
Galileo, GEOs, GPS and GPS Modernization (C/A-code on L2 and L5) as well as
dual-frequency P-code measurements. The user can also emulate signals on additional
carrier frequencies defined by the user.
Satellite constellation emulator
(supports GPS and Glonass as well as user-defined constellations). In addition to ideal
circular orbits, YUMA-format broadcast almanacs can be used.
Emulation of C/A and P-code

frequencies. (thermal noise, ionospheric and tropospheric delay, diffuse
multipath)
