A Novel Channel Model for Land Mobile Satellite Navigation
نویسندگان
چکیده
In 2002 the German Aerospace Centre (DLR) performed a measurement campaign of the land mobile multipath channel. From this data we derived a channel model that is synthesising the measured channel impulse response. It allows the realistic simulation of the multipath channel by approximating every single reflection. This model includes time variant reflectors approaching and receding in dependency of the azimuth and elevation of the satellite. All the signal processing had been realised independently of the transmitted signal. Therefore the usability for both, navigation systems (GPS as well as GALILEO) and wideband communication systems is given.

On land mobile satellite navigation performance degraded by multipath reception
In this paper simulation results of DLR’s ultra-wideband land mobile satellite (LMS) multipath channel model are presented. The goal is the evaluation of GNSS performance in the rail environment. For this safety of life (SOL) application an urban railway was identified as the most critical scenario. The channel model is based on a measurement campaign of the land mobile multipath channel perfor...

متن کاملAnalysis of Multipath Mitigation Techniques with Land Mobile Satellite Channel Model
Multipath is undesirable for Global Navigation Satellite System (GNSS) receivers, since the reception of multipath can create a significant distortion to the shape of the correlation function leading to an error in the receivers’ position estimate. Many multipath mitigation techniques exist in the literature to deal with the multipath propagation problem in the context of GNSS. The multipath st...
