14.5.2 Information Flow Between Lunar Lander and Ground
Equipment
Because the joint mode of the lunar lander and the lunar rover was applied in most of
flight phases, the processing of the test data both in single probe test mode and joint
mode should be considered in design of integrated test. The information flow and
information processing mechanism between the Chang’E-3 lunar lander and ground
test system with following characteristics is shown in Fig. 14.4.
