Title:
SYSTEM AND METHOD FOR DETECTING ATOMIC INTERFERENCE-BASED INERTIAL NAVIGATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2023/134105
Kind Code:
A1
Abstract:
Provided is a system for detecting atomic interference-based inertial navigation information (10), comprising a first sensing apparatus (20) and a calculation system (110). The first sensing apparatus (20) comprises a first atom source cavity (101), a second atom source cavity (102), an interference cavity (103), two first detectors (104), and at least one second detector (105). The first atom source cavity (101) is filled with two types of atoms, and the second atom source cavity (102) is filled with at least one of the two types of atoms. Also provided is a method for detecting atomic interference-based inertial navigation information, for use in the system for detecting atomic interference-based inertial navigation information (10).
