The Impact of Simplified UNBab Mapping Function On GPS Tropospheric Delay
The atmospheric delay issue is widely investigated in order to minimize the positioning error due to tropospheric and ionospheric delay. The mathematical modeling on the tropospheric model mapping functions should be revised and also simplified to represent simpler mapping function models. The zenit...

The atmospheric delay issue is widely investigated in order to minimize the positioning error due to tropospheric and ionospheric delay. The mathematical modeling on the tropospheric model mapping functions should be revised and also simplified to represent simpler mapping function models. The zenith tropospheric delay can be amplified by a coefficient factor called mapping function to form total tropospheric delay. The simplified UNBab mapping function models for both hydrostatics and non-hydrostatics can provide better understanding due to its simpler models compared to the established models. The simplified mapping functions for UNBab models for hydrostatic and non hydrostatic components are given in a form of hyperbolic rather than continued fraction form for the established models. By using linear, hyperbolic, logarithm and also regression method, the mapping function models can be simplified and at the same time can produce similar result with the original models. The calculation of tropospheric delay by using simplified UNBab models for both components does not give significant difference from the original models. |
