Analysis

The GPS data are being analysed using the GAMIT/GLOBK software. The Antarctic data are processed along with data from 70 to 80 global IGS tracking sites to calculate daily estimates of the site coordinates (along with orbital parameters). While there is insufficient data to allow an accurate rate of uplift to be estimated, the scatter of daily estimates seems to indicate that within a 5 year time frame we will be able to detect uplift of < 2 mm/yr. However, we acknowledge that there are many error sources (e.g. reference frame stability, antenna phase centre effects etc) which must be accounted for in order to achieve such precision.

Beaver Lake

Data have been collected at Beaver Lake since January 1998. View timeseries here. Results to date are inconclusive.

Dalton Corner

Data collection began in February 2000 and is only downloaded the following season. No timeseries is available at this time.

Landing Bluff

12 days data were collected at Landing Bluff in February 2000. View timeseries here.
