    What is NICT Sota instrumentation?
    The SOTA instrumentation was designed and developed at NICT in cooperation with NEC Corporation, NEC Toshiba Space Systems, Ltd. The development of SOTA started based on the proposed BBM (Bread Board Model) from an industry team. The model consisted of an optical part ( SOTA-OPT) and a controller ( SOTA-CONT ).

    How does Sota work?
    SOTA has a high performance microprocessor unit with SH-4 (LCPU : Local CPU). The LCPU processes the QD's signal in real-time, gimbal of SOTA, and tracks the beacon within ±100 µradians. The FPM (Fine Pointing Mechanism) is driven by other QD's for fine tracking of the light path of RX-4 within ±20 µradians.
