BeiDou/GPS Indirect Fusion Precision Orbit Determinationrlap is about 10?cm in radial direction for BeiDou IGSO. For MEO the accuracy is 15?cm in radial direction and for GEO is about 20?cm. The orbit RMS for GPS satellite is about 2?cm by comparing with IGS final products.

Research on High Accuracy Prediction Model of Satellite Clock Biasllite. There is an urgent need to develop the SCB prediction program for each satellite, here we use a combined method of least squares and auto-regressive model (LS?+?AR) from the EOP forecasting, to predict and assess SCB with data from IGS. Results show that the combined LS?+?AR method can improve the SCB forecast accuracy effectively.

Zero-Differenced Multi-GNSS Joint Precise Orbit Determination of BeiDou Satellites Based on AmbiguitEO is mostly better than 5?cm. After ambiguity fixing, the three dimensional precision of BDS is improved 21.8?% averagely, and the tangential precision is improved most obviously, especially for GEO.

Normal Anatomy of the Female Pelvis, of continuous operation reference station (CORS) stations. With 3D grid searching method, the obtained earthquake focus is basically consistent with USGS published results. It shows that the proposed method is effective and reasonable for strong ground motion monitoring by using high-rate GNSS observations, especially for seismic activity.

Radiological Imaging of the Kidney of 1–10?mm existing between the BDS- and GPS-derived ZTD, the inferred BDS-PWV and GPS-PWV is biased about 0.1–2?mm. And the final mean bias and STD of BDS- and GPS-PWV difference of all 5 stations is 0.78 and 1.73?mm. It is concluded that the PWV inferred from BDS can reach similar precision comparing to the GPS-PWV in the China region.
