摘要: One of the primary objectives future ARISTOTELES satellite mission is to map Earth's gravity field with high resolution and accuracy. In order achieve this objective, will be equipped a gradiometer Global Positioning System (GPS) receiver. error analyses have been performed for several combinations GPS observations. These indicated that bandwidth limitation prevents stable high-accuracy, high-resolution solution if no additional information available. However, addition high-accuracy observations, can obtained. A combination measurements acquired by high-quality receiver bandwidth-limited on board yield global model less than 100 km an accuracy better 5 mGal anomalies 10 cm geoid undulations.
