The estimation of the constituent densities of the upper atmosphere by means of a recursive filtering algorithm

Estimation and control for a sensor moving along a one-dimensional track

“…For example, small variations in the gravitational field of the earth are often measured and mapped using data obtained from ships which travel along prescribed trajectories [1,2]. Another important context in which this kind of problem arises is in the remote sensing of atmospheric variables using instruments carried in a satellite [3][4][5][6], and a final related application in the processing of blurred images obtained from moving cameras [7].…”

“…However, it is one that has found great use in practice [1][2][3][4][5][6][7]. For example, linear-guassian models for the deviation of a gravitational field from some idealized reference have been developed using both physicallybased models and statistical parameter identification techniques [1,2].…”

Estimation and Control for a Sensor Moving along a One-Dimensional Track,

“…For example , small variations in the gravitational field of the earth are often measured and mapped using data obtained from ships which travel along prescribed trajectories [ 1 ,2]. Another important context in which this kind of problem arises is in the remote sensing of atmospheric variables using instruments carried in a satellite (3)(4)(5)(6), and a final related application is the processing of blurred images obtained from moving cameras ( 7].…”

“…These observations have led researchers (1)(2)(3)(4)(5)(6)(7) to use one-dimensional formulations for the various problems that they have considered. On p ~ -3-the othe r hand , by restricting attention to one-dimensional tracks ,…”
