I am a series of GPSes coupled to a radar system installed on the Roi Baudouin Ice Shelf in East Antarctica. Follow me on Twitter @TweetinIceShelf were I continuously tweet my position. Watch how I advance into the ocean. I am deployed in December 2014.
GPS CDS: my current position is 70.4098S, 24.9965E. I moved 14.4629m in direction N337.9899E in 19 days.
GPS CGEO: my current position is 70.4038S, 25.0331E. I moved 15.0737m in direction N337.3602E in 19 days.
CGEO is slightly faster than CDS, and that is what is expected ;-)
