Fta Satellite Receivers

A dialect-neutral Smalltalk library which supports communication with NMEA enabled devices, such as GPS receivers. The initial specific target device will be a Magellan GPS315 receiver.

CoolTerm is a simple serial port terminal application (no terminal emulation) that is geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers, etc. The features of...

Individuals may also give the markers titles and descriptions, as well as position the map and choose between the map, satellite, and hybrid view types.Installation - Unpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules.

Timing recovery is a critical aspect of Digital Communications Receivers. This model uses a fractional delay implemented with a Farrow filter to create a symbol rate timing recovery subsystem.This is combined with a decision aided Carrier Recovery PLL. For testing, a transmitter with continuosly...

Let us assume the signal model:Y(k)=HX(k)+B(k)This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources. See reference [CHE91] Chen....

This toolbox contains a satellite tracker MSatTrack. You can input orbital parameters defined by yourself or existing ones (included). The tracking is done in 3D and the resulting grountracks are then plotted on a 2D map after the simulation is done. Several satellites can be simulated...


Platforms: Matlab

A collection of utilities for computing the impact propagation disturbances on satellite radio transmissions. Applications include frequency and temporal coherence estimates and examples that use waveform simulations. Models for common fading distributions and waveform detection probabilities in...

It is Time Reversal simulation in Matlab. Black circle is obstacle. Trialgle is detected obstacle position, red points is transmitters/receivers. It is 2d wave equation solution. Borders absorbs waves but not ideally so small reflection from borders exist. The waves are reflected from obstacle....
