Improving instantaneous atmospheric corrections for reflected GPS signals L1/L2 observation techniques with an integrated GPS receiver

The paper is intended to describe relationships of reflected GPS signals and environmental effect factors. No discussion of control would be complete without illuminating the software dimension. An altitude iteration loop into least squares searching for receiver position was modified and enhanced by giving 4 or more pseudo-ranges and ephemeredes and zooming on the plot to detect the search pattern. [1] The software is developed using MATLAB tools, which can display results of the reflected surface area altitude in real time. For the reflected signal application, it has been proven that a GPS receiver cannot smoothly detect reflected signals because under the underground base receiver system cannot smoothly receive the reflected GPS signals when the GPS signals are weak and discontinuously reflected. [2] This problem negatively impacts and reduces application of reflected signals. The design of an integrated receiver system permits smooth reception of the signals reflected by the water or ground. A rapid resolution altimetry method was developed by using surface elevations spectrum with the elevation angle and line of sight theory in the reflecting geometry and atmospheric corrections with ambiguity solution.
