EFP multi-functional bundle adjustment of Mapping Satellite-1 without ground control points[J]. Journal of Remote Sensing, 2012,16(S1):112-115. DOI: 10.11834/jrs.20120023.
Satellite photogrammetry without ground control points is an efficient method for global mapping
which has three ways:the first is that the attitude stability of satellite attains 1×10-6(°/s)
the second is high-precision attitude mensuration system
and the third is photogrammetry bundle adjustment.Because of the limitation of techniques
the only way to realize the photogrammetry without ground control points is photogrammetry bundle adjustment.When the research of bundle adjustment abroad couldn’t resolve the high-precision positioning without ground control points
we had developed the EFP(Equivalent Frame Photo)multi-functional bundle adjustment technique in Mapping Satellite-1 engineering
which included camera on-orbit calibration
bundle adjustment to whole three-lines intersection area
error compensation of attitude angle with low frequency and drift angle(yawing) effect processing.The technique was validated using Mapping Satellite-1 imagey datum.The results show that the positioning accuracy without ground control points had reached 10.3 m/5.7 m(plane/height)
and met the precision requirement of mapping topographical map on a scal of 1:50000.
