This research considers communication amongst a community of earth terminals through a collection of low altitude earth oriented satellites (LASAT) . In one proposed LASAT system, all satellites are identical and simultaneous transmission of near identical signals from several satellites creates interference at the earth receivers. Frequency hop sequence (FHS) is a new form of frequency hopping (FH) and is the proposed spread spectrum LASAT communications technique considered in this research. In military applications, the performance of the communications system in the presence of noise only, noise and jamming, noise and multipath or synchronization errors is of interest. FHS offers some immunity to jamming and multipath. This report presents the calculated noise performance of FHS in the presence of jamming, multipath and synchronization errors. For the noise only case, the calculated probability of bit error of a FHS system using eight symbols for a 10 dB value of the ratio of input bit energy to noise power density is 0.0002.
