The technical background of the NASA mobile satellite program is described, with attention given to the principal system parameters considered by NASA and JPL over the past decade. Recent system concepts and technology developments are discussed with emphasis on the mobile user terminal. Based on L-band channel studies, ground and space segment analyses, and field testing of developed mobile equipment, a first-generation LMSS configuration is proposed. In addition, a future system configuration with potential for significantly increased capacity is examined.
