Description

Method of providing satellite information based on computer-aided design method {METHOD FOR PROVIDING AN INFORMATION OF A SATELITE USING COMPUTER AIDED DESIGN}

The present invention relates to a method of providing information received from a satellite providing location information.

In the conventional survey method, a surveyor surveys the current situation using a survey instrument (level) and a scale (prism) in the field, stores the survey information on a diskette, etc., and brings it to the design room, based on the survey information. As a result, the construction of roads or buildings, etc. was performed separately using a computer aided design (CAD) program. In this survey method, real-time parallelism between surveying and drawing was impossible.

Accordingly, recently, a surveying method capable of displaying information on a surveyed structure directly on a portable terminal using surveying information collected in the field through a surveying device has been provided.

In this survey method, location information is received through a global navigation satellite system (GNSS) for deriving survey information, and the received location information is transmitted to a separate network RTK server through a user terminal.

The network RTK server generates a virtual reference point (VRS) and correction data based on the location information received from the user terminal, and then transmits the correction data to the portable terminal. The user terminal generates the corrected position information by correcting the previously measured and stored position information based on the correction data from the Network RTK server.

However, in the related art, when the user needs to know his position quickly during the survey, the user's terminal connection status and various connection statuses are not displayed on the user terminal together with the CAD drawing, which is inconvenient.

The present invention is to solve the above problems, the satellite information generated in communication with the satellite to display on the CAD drawing of the user terminal to increase the user convenience, computer-aided design based satellite information It aims at providing the provision method.

According to an aspect of the present invention, there is provided a method for providing satellite information based on a computer-aided design method, the method including: opening a CAD drawing by executing a survey program mounted on a user terminal; Performing communication setting and activating a GNSS device operation while the CAD drawing is open; And displaying satellite related information and location information on the CAD drawing.

According to the present invention, a method of providing satellite information based on a computer-aided design method includes satellite-related information and location information such as connection status and various connection statuses of satellites on a CAD drawing of a user terminal through a survey program installed in the user terminal. In this case, the user's convenience can be greatly increased.
