An FDM-CPM multi-user detector (30) jointly detects the received symbols for all users by determining from the received multi-user signal an a-posteriori probability mass function (pmf) of a time-sequence of states and transmitted symbols of all users, by iterative message passing corresponding to a specific factorisation of the pmf. The factorisation involves a combined variable representing possible transmitted symbols and CPM states of each user for each symbol time interval, so as to make the iterative process convergent. Non exponential complexity is enabled by disregarding multiple access interference (MAI) from at least some of the other users. Applications can include hubs for satellite communication ground stations.

The invention discloses an Ethernet-based unmanned aerial vehicle formation flight control data link system and belonging to the technical field of unmanned aerial vehicle formation control. The Ethernet-based unmanned aerial vehicle formation flight control data link system includes a ground station computer, a wireless data transmission ground terminal and a wireless data transmission airborne terminal. The wireless data transmission airborne terminal is mounted on an unmanned aerial vehicle and connected to a serial port of the airborne computer of the unmanned aerial vehicle. The wirelessdata transmission ground terminal and the wireless data transmission airborne terminal form a one-to-one communication link, and the wireless data transmission ground terminal is connected to an Ethernet serial port server through a serial port level conversion module, and the Ethernet serial port server and the ground station computer are respectively connected to an Ethernet switch through a network cable to form an Ethernet local area network. According to the Ethernet-based unmanned aerial vehicle formation flight control data link system, mature hardware, such as wireless data transmission, the serial port server and the Ethernet switch, is selected for construction to provide a data chain solution with reliable work, strong performance and controllable cost for an unmanned aerial vehicle formation operation control system.

The invention provides an object shooting method and device and a storage medium, the method is applied to a ground station communicating with a satellite, and the method comprises the following steps: obtaining the geographic position of a to-be-shot object; estimating a time point when the satellite flies to a position above the geographic position of the to-be-photographed object; obtaining meteorological conditions when the geographic position of the to-be-photographed object is at a time point; and controlling the satellite to shoot the to-be-shot object according to meteorological conditions. By pre-estimating a time point when the satellite flies above a geographic position of a to-be-photographed object, the ground station can control the satellite to shoot according to the meteorological condition when the position is at the time point, so that photos which cannot meet actual requirements due to meteorological reasons can be prevented from being shot as much as possible, waste of satellite resources is avoided, and the satellite resources are utilized more reasonably.
