Embodiment Construction

[0024] The method for utilizing the pendulum gyroscope of the present invention to measure the dimension of the earth specifically comprises the following steps:

[0025] Step 1, place the pendulum gyroscope at a certain station;

[0026] Such as figure 1 As shown, the pendulum gyroscope includes an outer casing 2, a suspension belt 3, a gyro motor room 4, a gyro motor 5, and a gyro shaft 14; The lower end of the belt 3 is connected to the gyro motor room 4, and the gyro motor room 4 is suspended inside the outer casing 2 through the suspension belt 3. The gyro motor room 4 is built with the gyro motor 5, and the gyro motor 5 is passed through the gyro motor shaft. 14 is connected with the gyro motor room 4; the external housing 2 is provided with a north mark 1, and the direction marked by the north mark 1 is the positive direction pointed by the gyro shaft 14, that is, the angular momentum when the gyro rotates at a high speed the direction of

Abstract

The invention discloses a method for measuring a latitude by utilizing a pendulum gyroscope, which particularly comprises the following steps of: 1, arranging the pendulum gyroscope at a certain station point; 2, measuring a swing period of the pendulum gyroscope; and 3, calculating the geographic latitude of the station point by using an external computer according to the obtained swing period of the gyroscope. The method of the invention has the advantages of simpleness, no need of large-scale ground-to-air connection survey, capability of independently measuring the latitude, higher late-time data processing speed and capability of monitoring variation of the latitude in real time.

Description

technical field [0001] The invention belongs to the technical fields of geophysics, geodesy and inertial navigation, and in particular relates to a method for measuring latitude, in particular to a method for measuring latitude by using a pendulum gyroscope. The invention can be widely used in the fields of aviation, spaceflight, global plate movement monitoring, deep space exploration research and the like. Background technique [0002] Due to the uneven distribution of the internal material flow of the earth itself, the latitude of the earth is constantly changing slightly, and the change of latitude also causes the change of the daily length of the day. Therefore, the accurate measurement of the change of latitude is very important for aviation, aerospace, The research of geophysics has important practical significance and application value. [0003] Since the 1970s, people have used a variety of observation technologies to measure latitude, such as VLBI technology, SLR ...
