Abstract	Inter-satellite link (ISL) will play an increasingly important role in the next generation of global navigation satellite system (GNSS). The inter-satellite distances in the GNSS vary greatly, resulting in a power loss difference of as much as 20 db. However, there are no reports on promotion of spectral efficiency in inter-satellite channels at present. In this study, the authors propose an efficient utilisation of the adaptive modulation and coding (AMC) scheme for ISLs in the GNSS. A novel method, based on inter-satellite distance, is presented for choosing the modulation and coding scheme (MCS). The proposed method provides a convenient way to estimate signal-to-noise ratio of the ISLs in GNSS. This AMC technique is implemented according to two different algorithms. One is the target bit error rate (BER) algorithm based on inter-satellite distance, aimed at keeping the BER below a target limit. The other is the maximum throughput algorithm based on inter-satellite distance, aimed at maximising the data throughput. In cases where the inter-satellite distance is short, simulation results show that, under the premise of the same transmission power, the throughput of two proposed AMC schemes is nearly six times that of a fixed MCS.
