| Descripción: | In the event of non availability of GPS/GLONASS satellite, Pseudolite only system has been proposed by many researchers. Pseudolite only system has constraint in placement of Pseudolite transmitters which leads to GDOP (Geometric Dilution of Precision) value very high for typical transmitter deployment scenarios. This high value of GDOP directly affects the position fixing accuracy and consequently pseudolite based system becomes unattractive for navigation systems where transmitter deployment constraint exists. In this paper a novel approach is proposed for mitigating the effect of high GDOP by combining pseudorange differencing and Ridge regression technique. The proposed approach is modeled and simulated for a typical scenario. The accuracy improvement by the proposed approach is validated with specially configured scenario using Inverted GPS without requiring Pseudolite transmitter and receiver hardware. |
