Description

Uplink carrier wave adding and adjusting self-adaptive adjusting method and device for near-earth space measurement and control network
Technical Field
The invention relates to the field of aerospace, in particular to a near-earth aerospace measurement and control network uplink carrier addition and adjustment self-adaptive adjusting method and device.
Background
The aerospace measurement and control task requires that the continuity and maximization of an uplink command sending time period are realized on the premise of reducing the tracking state change of measurement and control equipment and minimizing the frequency of point frequency switching. Therefore, the add/drop time of the uplink carrier needs to be determined according to the overlapping condition of the visible time periods of the measurement and control devices, and the dot frequency of each measurement and control device needs to be adjusted according to the actual distribution of the visible time periods of the measurement and control devices on the basis of preferentially using the initial dot frequency. The rule of the measurement and control equipment for adding and regulating the uplink carrier is as follows:
1. if the command time interval of a certain measurement and control equipment is completely covered by the command time intervals of other same-point-frequency measurement and control equipment, the equipment does not adjust the uplink carrier. As shown in fig. 1, device B does not tune up.
2. If the command time interval of a certain measurement and control equipment is completely covered by the command time intervals of two overlapped measurement and control equipment with the same dot frequency, the equipment does not adjust uplink carriers. As shown in fig. 2, device B does not tune up.
3. The uplink carrier switching rule when the command time interval of the measurement and control equipment is overlapped is as follows: when the command time periods of the two measurement and control devices are the same in grade, the command time period of the previous measurement and control device is prolonged as much as possible according to the 'exhaustion' principle of 'first-seen first-used and till exhaustion'. When the command time periods of the two measurement and control devices are different in grade, the command time period of the measurement and control device with the high grade is prolonged as far as possible.
Due to the flight orbit regression characteristic of the near-earth space spacecraft and the measurement and control network layout characteristic of the near-earth space spacecraft, the uplink starting dead zone regularly appears, and the continuity of the uplink starting time period is influenced for a long time; if the principle that the command time periods of the two measurement and control devices are the same in grade, namely that the command time periods are used first and used up is adopted, the carrier switching time of two adjacent time periods with the same dot frequency is fixed, and the generated uplink command sending blind area is solidified. The solidified uplink signaling blind area may not be covered by another point-frequency signaling time interval, and the continuity and maximization of the uplink signaling time interval of the measurement and control equipment cannot be realized.
