For almost 10years, the Gravity Recovery and Climate Experiment (GRACE) has provided information about the Earth gravity field with unprecedented accuracy. Efforts are ongoing to approach the GRACE baseline accuracy as there still remains an order of magnitude between the present error level of the gravity field solutions and the GRACE baseline. At the current level of accuracy, thorough investigation...
The GRACE (Gravity Recovery and Climate Experiment) mission was launched in March 2002 to determine the Earth's gravity model by using accurate measurements of the inter-satellite distance between two identical satellites. A strategy to combine two one-way ranging measurements, called dual one-way ranging (DOWR), is used to cancel out the common frequency noises of the oscillators embedded in the...
