Global Ocean Mass Change Estimation Using Low‐Degree Gravity Field From Satellite Laser Ranging

Geophysical Research Letters
Satellite laser ranging (SLR) is a well‐established geodetic technique for measuring the low‐degree time‐variable gravity field for decades. However, its application in mass change estimation is limited by low spatial resolution, even for global mean ...

Improved Simulated Annealing Algorithm on the Design of Satellite Orbits for Common-View Laser Time Transfer

Remote Sensing
Laser Time Transfer (LTT) has proven to be able to improve remote time transfer accuracy compared to microwave technology. The impact of satellite clock errors and atmospheric delays during LTT will be further reduced in the common-view mode.

Determination of precise positions of Titi Sima and Ishigaki Sima by satellite laser ranging. [PDF]

, 1991
Satellite Laser Ranging (SLR) Observations were carried out at Titi Sima and Isigaki Sima in 1988. The positions of these islands in the global geodetic network were determined by using SLR data obtained at these two islands, Simosato Hydrographic ...
