heal.abstract	A Land Mobile Satellite System (LMSS) propagation measurement campaign at 1.8 GHz was launched at Athens city center during June 1996 for high elevation angle (60 degrees, 70 degrees, and 80 degrees) channels. Four narrow streets with large building blocks and heavy traffic were tested. A new empirical model is extracted to calculate the link margin required to compensate for multipath fading in urban environments. A comparison with an existing model is presented. The results show considerable increase of the fade depth compared to suburban and rural environments. In general, the fade depth decreases with the increasing elevation angle, and the overall analysis indicates the strong dependence of the signal attenuation on the width of the streets, the average building height and the vegetation at the edges of the streets.	en
