The Ground Wave Prediction System (GWPS) provides detailed predictions of surface wave communication system performance in the medium frequency (300 kHz -3 MHz) and low HF (3-5 MHz) range. The program can be used to generate area prediction charts of ground-wave field strength, signal-to-noise ratio (SNR), and frequency range (single and multi-surface) for the user selectable transmitter location and area of interest. Many other two-dimensional plots can be generated. We do not recommend the use of GWPS for the prediction of VLF radio wave propagation.

GWPS 4 is an application designed to run under Microsoft Windows XP or Windows 7 installed on modern personal computers. The program will run under 32- or 64-bit versions of Windows 7. A minimum of 60 MB of hard disk space is required to install and run the program.

Please see the software downloads page for details of which platforms are supported by GWPS.
