Chapter
Inertial navigation technology can provide high-precision position and acceleration information when satellite navigation is not available, and unmanned systems tend to use inertial navigation as an auxiliary satellite navigation method in the realm of space in recent years. Based on the inertial navigation literature and the product information di...
Chapter
The lightweight demand of unmanned aerial vehicles (UAVs) has promoted the continuous upgrading of its body materials. After light metal materials such as aluminum alloy and titanium alloy, carbon fiber composite material has become the “main force” material of unmanned aerial vehicles. It can be said that the structure design and manufacturing tec...
Chapter
At present, it is difficult to continue the development of traditional logistics industry, and smart logistics is becoming an important source for the trans-formation and upgrading of the logistics industry. This article first analyzes the key technologies of smart logistics, from the three aspects of information platform related technology, intell...

... The modern world trends follow the path of miniaturization of measuring instruments. The development of micro/nano devices with low manufacturing cost and energy consumption but high accuracy is one of the priority areas [64,65]. There are many areas of application [66,67]: portable navigation devices, space satellites and probes, unmanned devices, etc. Large-scale and conventional instruments cannot be used there. ...
... With the gradual advancement of automation, digitalization, and intelligent upgrading, intelligent logistics has become one of the mainstream trends in the development of the logistics industry [1][2][3][4][5][6]. Through intelligent technical means such as intelligent software and hardware, Internet of Things, and big data, intelligent logistics can achieve refined, dynamic, and visualized management on each link of logistics and effectively improve the intelligent analysis and decisionmaking and automatic operation execution capabilities of the logistics system [7][8][9][10]. ...
... The previously mentioned challenges can be explained partially by the various epochs of developing artificial intelligence methods and tools for problem-solving (Li et al., 2020). Historically, five major families of ampliative computational mechanisms were proposed. ...
... It is undeniable that, as a navigation method according to the traditional Newton's law, its attitude error and velocity error oscillate periodically, and the position error keeps accumulating deviation. At present, in addition to inertial navigation in the underwater environment, with the diversification of detection methods, geophysical navigation, acoustic navigation, collaborative navigation, and other methods have emerged as required by time [3,4]. Geophysical navigation mainly uses the characteristics of geophysical parameters (topography, gravitational field, magnetic field) to obtain the current position information of the vehicle [5]. ...
