Station position and Earth Orientation Parameters (EOPs) solutions derived from analysis of Satellite Laser Ranging (SLR) data. These products are the generated by analysis centers in support of the International Laser Ranging Service (ILRS) and combined by the ILRS analysis coordinator to form the official ILRS EOP and station position product (daily and weekly).

Station position time series solutions in DORIS Station Coordinate Difference (STCD) format derived from analysis of Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) data. These products are the generated by analysis centers in support of the International DORIS Service (IDS).

Very Long Baseline Interferometry (VLBI) ASCII files in the NGS card format. Very Long Baseline Interferometry (VLBI) auxiliary ASCII files provided by the International VLBI Service for Geodesy and Astrometry (IVS) include schedules, notes, and session log files.

Very Long Baseline Interferometry (VLBI) is a geometric technique: it measures the time difference between the arrival at two Earth-based antennas of a radio wavefront emitted by a distant quasar. VLBI precisely locates points on Earth by comparing radio signals from a quasar radio source located in deep space received at different times at different Earth ground stations. This method gives relative positions of the Earth stations. VLBI data can be used to calculate information on Earth rotation, length of day, polar motion, baseline and velocities of stations. Products generated by VLBI contribute to research in many areas, including solid Earth, tides, studies of the vertical, fundamental astronomy, and VLBI technique improvement.

Celestial Reference Frame (CRF) product derived from analysis of Very Long Baseline Interferometry (VLBI) data. These products are the generated by analysis centers in support of the International VLBI Service for Geodesy and Astrometry (IVS) and combined by the IVS analysis coordinator to form the official IVS CRF product.

Troposphere Zenith Path Delay (ZPD) values derived from analysis of Very Long Baseline Interferometry (VLBI) data. These products are the generated by analysis centers in support of the International VLBI Service for Geodesy and Astrometry (IVS).

The daily Intensive solution files in SINEX format are analysis products that are mainly designed for combination, for both within the IVS and with other space techniques, since they contain datum-free normal equations (decomposed normal equations). Secondly, they allow to estimate UT1 for each 1-hour Intensive session applying a selected datum. Thirdly, the files contain estimates for all parameters (site positions, polar motion, UT1-TAI, and LOD), but these parameters, except UT1-TAI, have been tightly constrained to a priori values. The files are in SINEX format providing also the covariance matrix of the estimates. The SINEX product files are available on the same frequency as the EOP-I products: 24 hours after each new session data base is available.

Geocenter determination solutions derived from analysis of Doppler Orbitography by Radiopositioning Integrated on Satellite (DORIS) data. These products are the generated by analysis centers in support of the International DORIS Service (IDS).

경기도 하남시 ITS 체계 내 전광표지(VMS) 장비의 현황을 관리하기 위한 VMS 시설관리 기준정보로, 장치아이디·장치위치명·설치주소·좌표 등 위치 기반 정보를 통해 현장 점검 및 시설 자산관리에 필요한 기반자료를 제공합니다. 웹캠모델명은 현장 상황 모니터링 장비의 구성 요소를 나타내며, 설치일자와 사업명은 장비 연식·사업 이력 확인에 활용됩니다. 또한 모듈전원차단온도, 팬동작기준온도, 히터동작기준온도 등은 전광표지 하드웨어 보호설정으로, 온도 변화에 따른 장비 손상을 방지하는 핵심 파라미터입니다. 모듈장애판단확률기준, 재시도회수, 최대응답대기시간은 장애 발생 시 판단 기준과 통신 안정성을 확보하기 위한 값으로, 유지보수·고장판단 체계 구축에 중요합니다.
