Crossing Antarctica by Will Steger, Jon Bowermaster

By Will Steger, Jon Bowermaster

In March 1990, Will Steger accomplished what no guy had ever earlier than tried: the crossing of Antarctica, a complete of 3,700 miles, strolling. Lured through the problem and the great thing about Earth's final nice barren region, and made up our minds to concentration the world's consciousness at the frozen continent now that its ecological destiny hangs within the stability, Steger and his overseas Trans–Arctica workforce played a rare feat of patience.

This includes the name of the physical property which was measured by the sensor and the units in which it is measured. Often the units are defined implicitly in the way the system processes the measurement value. Spatial Location x. This is the position in space to which the measured physical property refers. In many cases the spatial location is not given explicitly and is instead defined implicitly as the position of the sensor element [2] . Time Instant t. This is the time when the physical property was measured.

2 σ m=1 m ∑ Since the sources Sm all supply the same piece of information, then y1 = y = y2 = . . = yM , σ1 = σ = σ2 = . . = σM , and thus 2 σML = σ 2 /M . yML = y , The 1/M reduction in uncertainty is clearly incorrect: it occurs because the node F assumes that each (ym , σm2 ), m ∈ {1, 2, . . , M}, represents an independent piece of information. In the method of covariance intersection we solve this problem by fusing the measurements ym , m ∈ {1, 1, . . , M}, using a weighted maximum likelihood estimate.
