  • SATNAV SIGNALS

    Satnav signals link the satellites to receivers in the user segment and the control segment. Like many other aspects of a satnav system, signals must be exquisitely engineered and carefully implemented in order for the system to provide the expected high levels of performance. This chapter provides an overview of signals and their mathematical representations, with an emphasis on direct-sequence spread spectrum (DSSS) signals and specific spreading modulations used for satnav. It introduces mathematical models for the effects of Doppler shift and propagation through the dispersive ionosphere. Satnav signals undergo Doppler shifts caused by a combination of satellite motion and receiver motion. The chapter provides a primarily qualitative discussion of satnav signal characteristics, identifying tradeoffs, and providing perspectives involving signal design choices. It then establishes the detailed mathematics of satnav signals, identifying characteristics, parameters, and models employed in descriptions of specific signals and in definition of receiver processing.

  • Recent Scientific Advances in Geospace Research Using Coherent and IncoherentScatter Radars

    Radio probing of the ionosphere was one of the first examples of remote sensing of man's environmental envelope, starting with the well-documented experiments of Marconi, and Appleton and Tuve in 1902. Over the intervening century, active radio remote-sensing techniques have developed very significantly, and have been applied to the study of ?>geospace,?> the closely coupled ionosphere-thermosphere-magnetosphere-solar-wind system. Geospace research now demands high-resolution spatial and temporal measurements. This has led to the development of new experimental techniques, such as the multi- beam, dual-site, high- and very-high-frequency radars. These have been matched by novel ways of exploiting existing radar techniques, such as digital ionosondes used to make routine measurements of winds in the thermosphere and plasma velocity in the ionosphere. The review concentrates upon recent advances of scientific knowledge arising from radar studies of geospace. It highlights developments that have occurred over a very wide range of altitudes, from the mesosphere (70-90 km) to the ionospheric signatures of reconnection on the nightside that are ?> 50-100 Re from the Earth's surface. The review also points briefly to the radar developments and scientific topics that will enhance further man's understanding of geospace in the next few years.
