Tropospheric and range biases in Satellite Laser Ranging [PDF]

Journal of Geodesy, 2021
AbstractThe Satellite Laser Ranging (SLR) technique provides very accurate distance measurements to artificial Earth satellites. SLR is employed for the realization of the origin and the scale of the terrestrial reference frame. Despite the high precision, SLR observations can be affected by various systematic errors.
