Technical Field
The application relates to the technical field of satellite antennas, in particular to a low-orbit satellite antenna turntable and a low-orbit satellite antenna.
Background
For low earth orbit satellite communication applications, the ground terminal is required to realize seamless satellite cutting, and the antenna can continuously track when the satellite passes through the right overhead. Current purely mechanical ground terminals, such as conventional X-Y type antennas and a-E type antennas, can solve the overhead problem.
The following practical defects exist in the prior several commonly-used turntable mechanisms for satellite over-the-top tracking and rotation envelope volume.
The A-E (azimuth-elevation) structure is the most common and is suitable for application of various antenna turntables, but when a low-orbit satellite passes through the top, a tracking blind area exists, and a software algorithm cannot solve the problem that an A shaft rotates 180 degrees rapidly or an E shaft rotates 90 degrees.
The X-Y is two fan-shaped structures, can realize the whole-sphere motion direction of 360 degrees, and is commonly used for tracking low-orbit satellites. However, whether the ground station is large or portable, the motion envelope is large because the distance between the two vertically superposed rotating axes and the antenna aperture surface cannot be reduced. Taking a 7.5 meter ground station as an example, a 14.2 meter diameter spherical cover is required, the cost and the floor space requirements are both large, and the corresponding weight of the whole machine is also too heavy.
In addition to the two structures, the Starlink phased array + A-E mechanical turret is the most advanced and compact form of structure today. However, the two shafts of the machine are in time-sharing motion, and the A-E shafts cannot work simultaneously. The above-described overhead problem exists if the antennas are not phased arrays with electrical scan compensation.
