Full analysis of static positioning types: Detailed introduction to the various classifications and characteristics of static positioning types

Introduction:
With the advancement of science and technology, positioning technology is in modern times plays an important role in society. In positioning technology, static positioning type is a common positioning method. This article will introduce in detail the various classifications and characteristics of static positioning types to help readers better understand and apply static positioning technology.

1. Absolute static positioning
Absolute static positioning refers to determining the position of an object by measuring the distance and azimuth angle between the object and a known reference point. Common positioning methods include Global Positioning System (GPS), Beidou Navigation System, etc. The biggest feature of absolute static positioning is that it has high accuracy and reliability, and can achieve positioning on a global scale. However, its disadvantage is that signal interference may affect positioning accuracy in complex environments such as indoors and canyons.

2. Relative static positioning
Relative static positioning refers to determining the position of an object by measuring the relative position relationship between the object and other objects. Common positioning methods include wireless beacon positioning, wireless sensor network positioning, etc. Relative static positioning is characterized by low positioning cost and flexible layout. It is suitable for indoor environments and scenes with low positioning accuracy requirements. However, its disadvantage is that due to factors such as base station deployment density and object obstruction, the positioning accuracy is lower than the absolute static positioning method.

3. Triangulation Positioning
Triangulation positioning is a common static positioning method. It measures the distance between an object and multiple reference points, and then uses the triangulation principle to calculate the position coordinates of the object. Common positioning methods include GPS, Beidou navigation system, etc. Triangulation positioning is characterized by high positioning accuracy and wide application range, and can meet the requirements of absolute static positioning and relative static positioning. However, its disadvantage is that it is affected by signal obstruction and multipath effects, and sometimes positioning errors occur.

4. Positioning based on signal strength
Positioning based on signal strength is a static positioning method that uses the received signal strength to determine the position of an object. Common positioning methods include Wi-Fi positioning, Bluetooth positioning, etc. Positioning based on signal strength is characterized by simple positioning equipment, low cost, and is suitable for short-range positioning. However, its disadvantage is that the positioning accuracy is limited due to factors such as signal propagation paths, multipath effects, and signal attenuation.

5. Positioning based on scope of influence
Positioning based on scope of influence is a static positioning method that determines the position of an object based on its scope of influence on the surrounding environment. Common positioning methods include infrared positioning, ultrasonic positioning, etc. Positioning based on the influence range is characterized by high positioning accuracy, low equipment requirements, and is suitable for indoor environments. However, its disadvantage is that the positioning accuracy will be reduced due to environmental interference and obstacles.

6. Multi-mode fusion positioning
Multi-mode fusion positioning refers to combining multiple static positioning methods and improving positioning accuracy and reliability by comprehensively utilizing the advantages of different methods. Common examples of this positioning method include inertial navigation systems and GPS, relative static positioning and comprehensive applications based on signal strength positioning. Multi-mode fusion positioning is characterized by high positioning accuracy and wide application range, which can meet positioning needs in complex environments. However, its disadvantages are high system complexity and high cost.

Summary:
Static positioning types include absolute static positioning, relative static positioning, triangulation positioning, signal strength-based positioning, influence range-based positioning and multi-mode fusion positioning, etc. Each positioning method has its own characteristics and scope of application. You can choose the appropriate positioning method according to actual needs. With the continuous development of science and technology, static positioning technology will be more widely used in various fields and bring more convenience to people's lives.
