Abstract : Longitudes associated with Doppler (laser) positioning measured by survey stations only possess relative significance. In order to obtain absolute longitudes, it is necessary to determine orientations of Doppler (laser) network longitude zero points in BIH-CIO systems. This article discusses making use of small numbers of optical observations to determine longitude zero point difference questions, giving dynamic determination and geometrical determination methods. In conjunction with this, discussions are made of their optimum observation conditions.
