Dennis Ogbe, 2024, "Two-way Ranging using OFDM Waveform with Application to Lunar Surface Navigation", https://doi.org/10.48577/jpl.4JCSRU, IEEE Aerospace Conference Big Sky, Montana, JPL Open Repository
We present a ranging system which measures the distance between two radio nodes by estimating the time of flight (ToF) of a series of short radio frequencybursts modulated using an orthogonal frequency division multiplexing (OFDM) waveform. ToF is estimated by periodically exchan... |
