Seamless positioning and navigation in the whole airspace and full-time domain is the technical commanding height of the positioning navigation industry in the future. With the rapid development of quantum precision measurement technology, gyro and inertial navigation systems based on quantum precision measurement have the advantages of high precision, small size and low cost, and will provide new disruptive technologies for seamless positioning and navigation.
The theme project of the "Twelfth Five-Year Plan" 863 Program Earth Observation and Navigation Technology "Key Technology of Micro-Small Atomic Spin Gyroscope Based on Magnetic Resonance" was undertaken by Beijing Institute of Automation Control Equipment, and the project research progressed for one and a half years. The project team has overcome the precision quantum control technology of nuclear spin-electron spin coupling polarization and detection, and completed the precision design and manufacture of small-scale magnetic resonance gas chamber, high-efficiency magnetic shielding and other components, and successfully developed the first magnetic based in China. Resonant atomic spin gyroscope principle prototype. The prototype has a zero-bias stability better than 2°/h, making it the second country in the world to master the technology. The gap with the US technology has narrowed from 10 years to 7 years.
The research results obtained by the project are to further improve the precision and integration of magnetic resonance-based micro-miniature atomic spinning gyroscopes, and lay a solid technical foundation for supporting the development of quantum navigation in China. The technological breakthrough of the atomic gyro makes the volume, quality, power consumption and cost of the existing seamless positioning navigation system applied to high-end equipment drop by about two orders of magnitude, which will be applied to the mass positioning navigation market, which can be used in a small volume and low cost. Under the condition, the meter-level positioning accuracy is realized, and the new space-free and full-time domain seamless positioning and navigation capability is provided.
Concerned about surprises
General Purpose Powder-Actuated System is used for building fastening, which have three parts: Actuated tools, Cartridges and fasteners. When Actuated tool strikes cartridge and cartridge will explode in the inner of tools and produce a lot of high temperature and high pressure gas. The gas will push the piston and the piston will push the fasteners into the basement. Or the gas will push the fasteners directly into the basement. Like this, we can fix a lot of things into concrete and steel basement tightly.
The fundamental is as the following:
The Actuated tools are classified for direct tools and undirect tools, we can also called high velocity and Low velocity tool, the fundamental is as the following:
High velocity tool:
Low velocity tool:
Based on different purpose, Cartridges are classified for different calibers and dimensions. The usual caliber and dimension is as the following:
.27calX11mm(S1)
.22calx15mm(S5)
.22calx16mm(S52)
.27calx18mm(S3)
.25calX16mm(S43)
At the same time, each caliber cartridge is classified for different specification based on the quantity of inner powder, which is marked by different color. when the color is more darker, the power level is stronger. otherwise, the power lever is lighter.
The fasteners are classified for different categories. Each different category is classified for different specification based on different length and diameter. At the same time, it is can also be re-designed based on special use.
The packages are as the following:
1. Tools: one tool/ plastic box/carton or five boxes/carton
2.Cartridge: 100pcs/paper or plastic box, 100boxes/carton.
3. Fasteners: 100pcs/paper box, XX boxes/carton.
For shipment, all cartons will packed by pallet.
