An approach is considered to determine the accuracy requirements for the spatial and angular position in the orbit of spacecraft performing remote sensing surveys. The approach is based on a method for determining errors in spatial coordinates obtained by solving a direct photogrammetric mark. The error model corresponding to an arbitrary position of the survey system in space allows using any Euler angle system as orientation angles. The proposed approach allows calculating the contribution not only of errors in the orientation parameters (in angles), but also the contribution of errors in the spatial position of the remote sensing spacecraft, in the parameters that characterize the optical shooting system, as well as the contribution of image measurement errors. This estimation is possible for any orbit and for any position of the remote sensing spacecraft in this orbit. This raises reliability in establishing the requirements to the accuracy of determining the spatial and angular position (reference) of remote sensing images of the Earth, i.e. the remote sensing spacecraft. The results of numerical experiments simulating different orbits and survey systems with different values of internal and external orientation elements are presented.
Keywords: geo-referencing of Earth remote sensing data, spacecraft orientation, accuracy estimation, spatial coordinates, mean square error, photogrammetric intersection, elements of external orientation, elements of interior orientation
