Analysis of the advantages and limitations of static positioning measurement principles

Abstract:
With the development of wireless communication technology, the application of positioning technology has gradually become popular. Static positioning is a method of determining the position of a receiver by measuring the distance or angle between the receiver and a known landmark. This article will analyze the advantages and limitations of the static positioning measurement principle and give some specific code examples.

1. Analysis of advantages of static positioning measurement principle

1. High precision:
   The principle of static positioning measurement is based on measuring the distance or angle between the receiver and known markers, using Triangulation method to calculate the exact position of the receiver. Due to the high measurement accuracy and small positioning errors in various directions such as altitude, latitude, and longitude, the static positioning accuracy is higher and is suitable for scenarios that require higher positioning accuracy, such as indoor navigation, geological exploration, etc.
2. Simple and easy to use:
   The principle of static positioning measurement does not require complex equipment and complex algorithm support. It only needs to measure the distance or angle between the receiver and known markers. Therefore, equipment using the static positioning measurement principle is simple to operate and easy to use and maintain.
3. Low cost:
   Compared with other positioning technologies, the equipment cost based on the static positioning measurement principle is lower. Because the static positioning measurement principle can be measured using common distance and angle sensors, these sensors are low-cost and easy to use. At the same time, it does not require a large amount of computing and storage resources, saving equipment costs.

2. Analysis of limitations of static positioning measurement principle

1. Affected by interference:
   The static positioning measurement principle is easily affected by external interference, such as buildings and the atmosphere , electromagnetic field, etc. Especially in indoor positioning scenarios, the presence of obstacles will interfere with the positioning results, causing the positioning accuracy to decrease.
2. Need to arrange markers in advance:
   The principle of static positioning measurement requires markers to be arranged in the measurement area in advance so that distance or angle measurements can be performed. Therefore, in some special scenarios, such as wild environments, rapid deployment, etc., it is difficult to arrange markers in advance, making static positioning impossible.
3. Unable to achieve real-time positioning:
   The static positioning measurement principle requires measuring the distance or angle between the receiver and the marker, and calculating the position of the receiver through triangulation. This process takes a certain amount of time and is focused on the next positioning. Therefore, real-time positioning requirements cannot be achieved, and it is suitable for scenarios that require positioning at a certain interval.

3. Static positioning measurement principle code example

The following is a simple code example that uses the static positioning measurement principle to calculate the receiver position:

def get_receiver_position(distance1, distance2, angle1, angle2):
    # 根据已知的距离和角度，计算接收器的位置
    # TODO: 根据具体的三角定位算法来实现

if __name__ == "__main__":
    distance1 = 10  # 接收器与第一个标志物之间的距离
    distance2 = 8  # 接收器与第二个标志物之间的距离
    angle1 = 45  # 接收器与第一个标志物之间的角度
    angle2 = 60  # 接收器与第二个标志物之间的角度

    receiver_position = get_receiver_position(distance1, distance2, angle1, angle2)
    print("接收器位置：", receiver_position)

The above code The example only shows a simple static positioning calculation process. In actual applications, the algorithm may need to be optimized and implemented based on specific scenarios and requirements.

Conclusion:
The static positioning measurement principle has the advantages of high accuracy, simplicity and ease of use, and low cost. However, limitations such as the impact of interference, the need to arrange markers in advance, and the inability to achieve real-time positioning cannot be ignored. In practical applications, it is necessary to comprehensively consider its advantages and limitations based on specific scenarios and needs, and select appropriate positioning technology to achieve positioning goals.
