Utilization of an NNSS receiver in the explosion seismic experiments on the Prince Olav Coast, East Antarctica 2. Positioning
Performance tests of a one-wave (400MHz) NNSS receiver and a two-wave (150 MHz and 400 MHz) NNSS receiver were made at Syowa Station, East Antarctica. The two-dimensional positioning by a one-wave receiver scattered with the standard deviation of about 200m from the mean position determined by many...

Performance tests of a one-wave (400MHz) NNSS receiver and a two-wave (150 MHz and 400 MHz) NNSS receiver were made at Syowa Station, East Antarctica. The two-dimensional positioning by a one-wave receiver scattered with the standard deviation of about 200m from the mean position determined by many passes. The two-dimensional positioning by the two-wave receiver scattered with the standard deviation of 25m for the latitudinal direction and 50m for the longitudinal direction, respectively. The mean position by many passes by the one-wave receiver and that by the two-wave receiver were relatively located within 70-80m.
