Embodiment 1

[0045] For ease of understanding, see figure 1 , Embodiment 1 of a transmission power adaptive adjustment method of an RTK reference station provided by the present application, comprising:

[0046] Step 101. The base station controls the radio station to send the preset differential correction data to the mobile station with the initial transmission power, prompting the mobile station to perform correction positioning calculation according to the preset differential correction data, and obtain the differential delay time. The initial transmission power is the maximum value of the base station transmit power.

[0047]It should be noted that the base station is an RTK base station. During the positioning operation, the host of the base station keeps its position unchanged, but the mobile station will change its position according to the position requirements of the operation. The change of distance will affect the distance between the base station and the mobile station. The d...

Embodiment 2

[0053] For ease of understanding, see figure 2 , the present application provides a second embodiment of a transmission power adaptive adjustment method of an RTK reference station, including:

[0054] Step 201. Obtain preset differential correction data in real time through the preset satellite receiving module.

[0055] It should be noted that the satellite receiving module is used to receive GNSS satellite signals and output differential correction data in real time, and only needs to start the base station function of the satellite receiving module.

[0056] Step 202: The base station controls the radio station to send the preset differential correction data to the mobile station with the initial transmission power, prompting the mobile station to perform correction and positioning calculations according to the preset differential correction data, and obtain the differential delay time. The initial transmission power is the maximum value of the reference station. transmi...

Abstract

The invention discloses a transmitting power self-adaptive adjustment method of an RTK reference station and a related device, and the method comprises the steps: enabling a reference station controlradio station to transmit preset differential correction data to a mobile station at an initial transmitting power, enabling the mobile station to carry out the correction positioning calculation according to the preset differential correction data, and obtaining a differential delay duration, wherein the initial transmitting power is the maximum transmitting power of the reference station; in thefirst preset delay time, receiving the differential delay duration transmitted by the mobile station through the reference station; and adaptively adjusting the initial transmitting power according to the differential delay duration and a delay threshold to obtain updated transmitting power, wherein the differential delay duration is positively correlated with the updated transmitting power. Thetechnical problem that an existing transmitting power adjusting method wastes time and labor and lacks self-adaptability, and consequently the positioning correction operation efficiency is low is solved.

Description

technical field [0001] The present application relates to the technical field of measurement and control, in particular to a method for adaptively adjusting transmission power of an RTK reference station and related devices. Background technique [0002] The RTK (Real-Time Kinematic) host is an important high-precision GNSS (Global Navigation Satellite System: Global Navigation Satellite System) positioning device in the current surveying and mapping field. The RTK reference station transmits the differential correction data to the mobile station in real time through the built-in radio station, so that the mobile station host can achieve high-precision positioning after calculation. This method of using the built-in radio station for differential correction data transmission is a common way for RTK to work normally. At present, the transmit power of built-in radios of RTK reference stations on the market is generally divided into three grades, namely high, medium and low. ...
