Abstract :
Mobile satellite systems allow truly ubiquitous wireless communications to users anywhere and anytime. NASA´s Advanced Communications Technology Satellite (ACTS) provides an ideal space-based platform for the measurement of K/Ka-band propagation characteristics in a land mobile satellite application. Field tests for K-band propagation were conducted in three basic environments: clear line-of-sight (LOS) highways, lightly shadowed suburban, and heavily shadowed suburban. Preliminary results of these field tests indicate very little multipath for rural environments and for clear LOS links while deep fades were experienced in shadowed areas, especially those where tree canopies covered the road
