图7 Io-DAM射电爆发的地球观测几率构型限制Fig. 7 The space chance to observe the Io-DAM radio burst from the Earth

位于月球背面表面的着陆器在月昼期间都可以随时加电工作。它们每隔几天就会有对木星10米波爆发进行观测的机会。而对于地面探测者而言，指定的测站由于所处位置的纬度和地球自转的限制，最多每周有一次机会，每个月有一次遇到信号极大的机会。在考虑星–地协同观测时，可选地面设备包括位于荷兰的LOFAR中心阵、明安图日像仪观测基地和山东大学槎山太阳射电频谱仪。预报3站观测Io-A、Io-B、Io-C的可能时段，与“嫦娥四号”的空间低频设备运行时间重叠，即可协同实施。可以预期携带低频射电探测设备的月球探测任务有希望在地球AKR辐射爆发的周日和季节性爆发、月球轨道运动队AKR的调制，以及在木星10米波射电爆发的连续测量等方面取得新的成果。
