| Abstract: |
It is well
established that the position co-ordinates of the receiving antenna should be
determined precisely in advance for getting time of the GPS receiver through a
single GPS satellite technique. So it is desirable to know the extent of
accuracy of the position coordinates required for a particular timing accuracy.
In this paper, an analytical expression relating to the position error and the
corresponding error in the time of the GPS receiver has been derived. Time of
the GPS receiver error caused by the error in position coordinates largely
depends on the position of the satellite indicated by the respective elevation
and azimuth of the satellite. To validate the derived formulation, it is
important to configure the experimental plan judiciously. A special experiment
has accordingly been conducted at National Physical Laboratory, New Delhi, India
(NPLI). The observed data have been found to tally well with the derived
relation.
