Situation assisted indoor localization using signals of opportunity
2014 International Conference on Indoor Positioning and Indoor Navigation (IPIN), 2014Development of an accurate, less-complexity indoor positioning system using Smartphone is the scope of this research. In an indoor environment, a Smartphone can communicate with the signals of opportunity. The signals for experimentation include Wi-Fi, Bluetooth, GSM and optical signals which will almost be available in all the buildings and a ...

Calibration of active arrays using signals of opportunity
IEE Seminar on Calibration of Active Phased Array Antennas, 2005The advantages of active phased array radars could be made available to a much wider range of radars than is possible at present, if the arrays could be made cheaper. The work described here has been studying how arrays may be calibrated using targets in the radar's environment can be used for calibration or astronomical sources, such as the sun.

Recursive Range Estimation Using Astrophysical Signals of Opportunity
Journal of Guidance, Control, and Dynamics, 2017An estimator for determining the range of a space vehicle relative to some origin by using astrophysical signals of opportunity is developed. The signals used are x-ray photons emitted by pulsars.

MULTIPLE SIGNALS OF OPPORTUNITY FOR LAND REMOTE SENSING
2023Multiple Signals of Opportunity (multi-SoOp) across different frequencies and polarizations offer a potential breakthrough for remote sensing of root-zone soil moisture (RZSM). Deeper penetration depths of existing communication transmissions in the frequency ranges of 137–138, 240–270, and 360–380 MHz enable the estimation of RZSM by complementing ...
