### MSIMP Applications in Different Areas
In addition, economics and cost analysis optimize satellite resource allocation through weighing the costs and benefits of mission replanning to ensure the maximum mission benefits and resource utilization under the premise of controllable costs [24]. MSIMP has a wide range of application areas. In the field of environmental monitoring and protection, MSIMP is applied to monitor forest cover and track water resources like lakes and rivers [25]. In disaster monitoring and emergency response, MSIMP is used to track geological disasters like earthquakes and mudslides and to provide prompt early warnings and assessments of forest and urban fires [26]. In the field of agriculture and food security, MSIMP is used to monitor crop growth and land use [27]. In the field of urban planning and management, MSIMP is often used as a tool to control the urban traffic flow [28]. In the field of resource exploration, the superior imaging technology of MSIMP is used to monitor the distribution of surface minerals [29]. This section describes the execution process of MSIMP using forest fire monitoring as a concrete instance, as shown in Figure 3.  
In the pre-processing phase, suitable orbital parameters are designed through satellite dynamics to ensure comprehensive coverage of the global forest area. Remote sensing technology is used to select and calibrate high-resolution satellite imaging sensors, while system engineering is responsible for defining the mission requirements and developing the system architecture to ensure the orderly integration of all aspects of the mission. In the mission planning stage, optimization algorithms prioritize satellite observation areas based on fire risk assessment data, allocating satellite resources to high-risk regions to focus on monitoring potential fire hotspots. Image-processing technology is then used to plan the satellite's imaging path, ensuring the spatial continuity and temporal consistency of the data. Additionally, control theory is applied to design and optimize the satellite's trajectory, ensuring accurate tracking of the designated imaging path. In addition, the MSIMP system has reserved a spare fault-tolerant window to cope with system failures, mission delays, or other unforeseen events beyond the time period between the satellite and the ground target that satisfies, for example, the resolution, sunlight, etc., so as to ensure that the mission can be carried out smoothly. Entering the executive phase, the satellite monitors the forest area in real time as planned, and once the sensors detect fire smoke, the observation data will be rapidly transmitted via communication technology to the ground station, which uses image-processing technology to quickly identify the fire area and notify the emergency response authorities of the information. According to the development of the fire, the system dynamically adjusts the imaging mission and trajectory
