Abstract The ISEE 1–2 propagation experiment determines the integrated electron density along the line of sight between the ISEE 1 and 2 satellites by measuring the phase advance introduced onto a radio wave transmitted by ISEE 1 and received by ISEE 2. This experiment has been used for three distinctly different types of study. In the solar wind, the noise-like spectrum is made up of two power-laws, with the flatter spectrum at frequencies above 0.1 Hz; this solar wind noise shows little evidence of anisotropy. In the magnetosheath spectral analysis shows discrete spectral features at MHD frequencies; cross spectral analysis with the magnetic field fluctuations observed by the UCLA magnetometer permits the identification of the corresponding MHD wave modes. The propagation experiment is also being used for probing discrete density structures, in particular the “shocklets” and their associated structures observed in the proton foreshock.
