Abstract: The formation of plasma beams is a ubiquitous consequence of energy propagation through a magnetized plasma.   Within geospace, the beam energy is ultimately dissipated as heat, light, ionization, and turbulence in the outer atmosphere.   Careful measurement and assimilation of these responses provides a remarkably versatile remote sensing diagnostic of  both magnetospheric and ionospheric physics.   This talk reviews recent research on beam-ionosphere interactions, and their manifestations in incoherent scatter radar (ISR), multi-spectral auroral imagery and, most recently, signals from Global Navigation Satellite Systems (GNSS).   The latter, in particular, exemplifies the synergy between operations and research that embodies the National Space Weather Program..
