A software gps simulator, providing TCP/IP, UDP, http and serial port connectivity in NMEA 0183, XML or user defined output format.
Usable for testing all kinds of GPS applications.
Can playback pre-recorded GPS files with NMEA output.
finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method
This is a small program to show impedances in a Smith Chart. The chart is drawn (it is not an image), so it can be redimensioned without pixeling. As it's done with Qt 4, it should run in multiple platforms.
