Description
본 발명은 전지구 위성항법 시스템(GLOBAL NAVIGATION SATELLITE SYSTEM, GNSS)과 단일 주파수 반송파 위상 데이터를 사용하는 GNSS 수신기를 이용하여 지진 및 화산 등에 의한 지표 변형을 측정하는 기술에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for measuring an earth's surface deformation caused by earthquakes and volcanic eruptions using a global navigation satellite system (GNSS) and a GNSS receiver using single frequency carrier phase data.
글로벌 네비게이션 위성 시스템(Global Navigation Satellite System, GNSS)은 인공위성을 이용하여 지상물의 위치, 고도, 속도 등에 관한 정보를 제공하는 시스템을 말한다. The Global Navigation Satellite System (GNSS) is a system that provides information on the location, altitude, and speed of terrestrial objects using satellites.
본 발명은 전지구 위성항법 시스템과 단일 주파수 반송파 위상 데이터를 사용하는 GNSS 수신기를 이용하여 지진 및 화산 등에 의한 지표 변형을 측정하는 것을 목적으로 한다.An object of the present invention is to measure ground deformation caused by earthquakes and volcanic eruptions using a global satellite navigation system and a GNSS receiver using single frequency carrier phase data.
상기의 목적을 이루기 위한, 실시간 지표변형 측정을 위한 GNSS 단일 주파수 RTK 측위 장치는 단일 주파수 반송파 위상 데이터를 수신하는 인터페이스부와, 상기 단일 주파수 반송파 위상 데이터에 기초하여, 수신기의 안테나가 설치된 지점의 좌표를 결정하는 프로세서를 포함할 수 있다.In order to achieve the above object, a GNSS single-frequency RTK positioning apparatus for real-time ground deformation measurement includes an interface for receiving single frequency carrier phase data, And a processor that determines the processor.
본 발명의 실시예에 따르면, 전지구 위성항법 시스템과 단일 주파수 반송파 위상 데이터를 사용하는 GNSS 수신기를 이용하여 지진 및 화산 등에 의한 지표 변형을 측정할 수 있다.According to an embodiment of the present invention, an earth deformation caused by earthquakes and volcanic eruptions can be measured using a global satellite navigation system and a GNSS receiver using single frequency carrier phase data.
도 1은 본 발명의 일실시예에 따른 실시간 지표변형 측정을 위한 GNSS 단일 주파수 RTK 측위 장치의 구성을 나타내는 도면이다1 is a diagram showing a configuration of a GNSS single-frequency RTK positioning apparatus for measuring real-time land deformation according to an embodiment of the present invention
GNSS는 지구 주위를 궤도 운동하고 있는 GNSS 위성 신호를 이용하므로 GNSS 신호가 지상의 사용자에게 수신되기 위해 전리층과 대류층을 포함한 지구 대기권을 통과하면서 신호 지연량의 변화 등을 겪게 된다.Because GNSS uses GNSS satellite signals orbiting the earth, GNSS signals pass through the Earth's atmosphere, including the ionosphere and the convection layer, to undergo changes in signal latency in order to be received by users on the ground.
GNSS는 안테나가 설치된 지점의 좌표를 정밀하게 결정하므로 안테나 설치점이 육상, 해상 및 항공 등을 가리지 않고 GNSS 신호 수신이 가능하고 안테나 설치가 가능한 곳이라면 어디든지 정밀한 위치를 결정할 수 있다. 일례로 지표에 설치된 안테나를 이용할 경우 지표의3차원 변형을 정밀하게 측정하는 센서로서 활용할 수 있다. 이를 이용하여 화산 및 지진과 같은 자연 재해에 의해 발생하는 지표 변형을 정밀하게 측정하는 것이 가능하다.GNSS precisely determines the coordinates of the point where the antenna is installed, so that the antenna installation point can receive the GNSS signal regardless of land, sea or air, and can determine the precise location where the antenna can be installed. For example, when using the antenna installed on the surface, it can be utilized as a sensor for precisely measuring the 3D deformation of the surface. Using this, it is possible to precisely measure the surface deformation caused by natural disasters such as volcanic and earthquakes.
본 발명의 실시예에 따른 실시간 지표변형 측정을 위한 GNSS 단일 주파수 RTK 측위 장치는 도 1에 도시된 바와 같이, 인터페이스부 및 프로세서를 포함할 수 있다. 이때, 인터페이스부는 단일 주파수 반송파 위상 데이터를 수신할 수 있다. 프로세서는 상기 단일 주파수 반송파 위상 데이터에 기초하여, 수신기의 안테나가 설치된 지점의 좌표를 결정할 수 있다.A GNSS single-frequency RTK positioning apparatus for real-time land deformation measurement according to an embodiment of the present invention may include an interface unit and a processor as shown in FIG. At this time, the interface unit can receive the single frequency carrier phase data. Based on the single frequency carrier phase data, the processor can determine the coordinates of the point where the antenna of the receiver is installed.
본 발명의 실시예에 따른 실시간 지표변형 측정을 위한 GNSS 단일 주파수 RTK 측위 장치는 GNSS 이중 주파수 수신기 대신 단일 주파수 수신기를 사용하여, 비용을 매우 절감할 수 있다. 따라서, 본 발명은 기존의 지표 변형 측정 GNSS 수신기가 이중 또는 삼중 주파수를 반송파로 사용 함에 따라, 통상 수천만원 대의 고비용이 소요되고, 넒은 면적의 지표 변형을 측정하고자 할 경우 많은 수의 수신기가 필요하게 됨에 따라, 장비 설치 비용이 대폭 증가하게 되며, 또한 화산과 같은 위험 지역에 설치된 수신기의 경우 분화 시 파괴될 가능성이 높아 비용 손실을 야기하게 되는 문제점을 극복할 수 있다.A GNSS single frequency RTK positioning device for real-time land deformation measurement according to an embodiment of the present invention uses a single frequency receiver instead of a GNSS dual frequency receiver, which can greatly reduce the cost. Therefore, according to the present invention, when a conventional GNSS receiver uses a double or triple frequency as a carrier, it usually requires a high cost of several tens of thousands of won, and a large number of receivers are required As a result, the installation cost of the equipment is greatly increased. Also, in the case of a receiver installed in a dangerous area such as a volcano, it is highly likely to be destroyed at the time of differentiation, thereby overcoming the problem of causing cost loss.
또한, 본 발명의 실시예에 따른 실시간 지표변형 측정을 위한 GNSS 단일 주파수 RTK 측위 장치는 외부 수신기 네트워크와 연동 함으로써, 단일 주파수 수신기의 경우 자체적으로 전리층 오차를 정밀하게 제거하기 힘든 부분을 극복할 수 있으며, 또한 미국 GPS 외에 러시아 GLONASS와 중국 BeiDou, 그리고 유럽연합 Galileo 신호까지 활용 함으로써, 가용 신호의 개수를 증가시켜 정확도를 향상시킬 수 있다.In addition, the GNSS single-frequency RTK positioning apparatus for real-time ground deformation measurement according to an embodiment of the present invention works in conjunction with an external receiver network to overcome a difficulty in precisely removing ionospheric errors in a single- In addition to using US GPS, Russian GLONASS, China BeiDou and EU Galileo signals can be used to improve the accuracy by increasing the number of available signals.
본 연구는 지표 변형을 유발하는 자연 재해 관측과 사회 중요 시설 감시 등의 분야를 위해 미국 GPS, 러시아 GLONASS, 중국 BeiDou 및 유럽연합 Galileo 신호를 모두 활용하는 단일 주파수 GNSS 수신기 네트워크를 이용하여 지표 변형을 cm 수준으로 실시간 정밀 산출하는 기법에 대한 것이다.This study uses a single frequency GNSS receiver network that utilizes US GPS, Russian GLONASS, China BeiDou, and European Union Galileo signals for areas such as natural disaster observations and social critical facility monitoring, Level precision in real time.
