Patent EP-0249666-A3 (EP)
IPC: B64G1/36
Filed: 1986-12-15
Abstract: Pixels within a satellite camera (1, 2) image are pre­
cisely located in terms of latitude and longitude on a celes­
tial body, such as the earth, being imaged. A computer (60) 
on the earth generates models (40, 50) of the satellite's orbit 
and attitude, respectively. The orbit model (40) is generated 
from measurements of stars and landmarks taken by the 
camera (1, 2), and by range data. The orbit model (40) is an 
expression of the satellite's latitude and longitude at the 
subsatellite point, and of the altitude of the satellite, as a 
function of time, using as coefficients (K) the six Keplerian 
elements at epoch. The attitude model (50) is based upon 
star measurements taken by each camera (1, 2). The atti­
tude model (50) is a set of expressions for the deviations in 
a set of mutually orthogonal reference optical axes (x, y, z) 
as a function of time, for each camera (1, 2). Measured data 
is fit into the models (40, 50) using a walking least squares 
fit algorithm. A transformation computer (66) transforms 
pixel coordinates as telemetered by the camera (1, 2) into 
earth latitude and longitude coordinates, using the orbit and 
attitude models (40, 50).
