Abstract: A three-dimensional positioning method includes establishing the geometric model of optical and radar sensors, obtaining rational function conversion coefficient, refining the rational function model and positioning the three-dimensional coordinates. Most of the radar satellite companies and part of the optical satellite only provide satellite ephemeris data, rather than the rational function model.

Finally, the observation equation is established by the rational function model to solve the three-dimensional coordinates. It is obvious from the above results that the integration of optical and radar images does achieve the three-dimensional positioning.

Such a radio transmission schedule of neighboring nodes can include information on when neighboring nodes will be receiving or transmitting data. The scheduling manager then schedules radar events to be executed by the radar device at available times, or at times that do not overlap with scheduled radio events.
