摘要: | An overview of past accomplishments is presented that shows the development of satellite time transfer techniques and capabilities that are used today. The development is traced from the concepts and early demonstrations using a single satellite to the global coverage now provided by a constellation of satellites. Predictions of future technology are compared with what has been accomplished over the last 25 years. Co-operative experiments performed jointly by colleagues of the PTTI Meetings were key to the development. These experiments demonstrated the potential of time transfer by satellites having global coverage. Some of the results are reviewed and compared to current capabilities. |
