This invention discloses a method and apparatus for zero-value traversal measurement of satellite ground station equipment combinations. The method includes: selecting one set of links as the initial link and determining the zero value of the ground station equipment combination corresponding to the initial link; based on the initial link, performing a partial zero-value combination traversal test on the ground station equipment of the satellite ground station system; obtaining the relative difference of zero values ​​for each input segment of adjacent ground station equipment groups in the satellite ground station system based on the zero-value combination traversal test results; and calculating the zero value of the target ground station equipment combination based on the zero value of the ground station equipment combination corresponding to the initial link and the relative difference of zero values ​​for each input segment of adjacent ground station equipment groups. The target ground station equipment combination refers to the equipment combination performing the user target ranging task. As can be seen, this invention first completes the zero-value measurement of a portion of the equipment combinations, and then performs zero-value conversion for the remaining combinations, achieving zero-value traversal of ground station equipment combinations while maintaining short time commitment and meeting the required measurement accuracy.

The utility model provides a fixing device for micro pile embedded section steel. The fixing device comprises an adjustable supporting rod, an anchoring chassis and an adjustable section steel hoop. The adjustable profile steel hoop is of a hoop structure with the shape of an inner opening matched with the shape of the embedded profile steel, the size of the inner opening of the adjustable profile steel hoop is adjustable, and the adjustable profile steel hoop is used for surrounding and fixing the embedded profile steel. The upper ends of the adjustable supporting rods are hinged to the periphery of the adjustable profile steel hoop, the anchoring chassis is installed at the bottom ends of the adjustable supporting rods, and the length of the adjustable supporting rods is adjustable. The anchoring chassis is used for being fixed to the ground. The device has the advantages that the labor intensity of workers is reduced, the construction efficiency is improved, the use of engineering instruments is reduced, and the construction cost is reduced.
