Goel, G K
Mathur, B S
|Abstract:||The Global Positioning Satellite System (GPS) signals are being extensively used for worldwide time comparison. The National Physical Laboratory (NPL), New Delhi, has also been utilizing GPS signals for comparison of time for a long time and has been contributing to the Coordinated Universal Time (UTC) maintained at BIPM, Paris. This paper explains the experimental setup of the network of international time link via GPS. The detailed analysis of data has been presented. It highlights a quantitative estimate of the deterioration of time accuracy as a result of introduction of selective availability in the GPS system.|
