A 3D heterogeneously integrated guidance, navigation, and control micro-system

摘要

A GNC micro-system which is developed by 3D heterogeneous integration is presented in this paper. The SRAM, SoC, and FPGA chips are integrated onto a silicon interposer. Other chips are mounted on different MCM substrates. The whole 3D GNC micro-system is packaged using POP technology. The volume is reduced from 120 x 120 x 80 mm(3) to 40 x 40 x 23 mm(3), and the weight is reduced from 1.5 kg to 300 g. The stability of the three axis gyroscopes in the GNC micro-system is 3.11 degrees h(-1), 3.25 degrees h(-1) and 4.26 degrees h(-1), and the accuracy is 5 degrees h(-1). The positioning output stability of the satellite navigation receiver is better than 1 m under static conditions. (C) 2019 The Japan Society of Applied Physics
