Setting up the Satellite Oriented Control Control Points

In order to build a complete and standardized satellite oriented control point system of the utmost precision, in planning for the system the MOI had referred to the conventional triangulation point and the satellite oriented control points installed by the Academia Sinica and take into consideration the physical distribution and practicability of these control points. At the moment altogether 105 Order 1 and 621 Order 2 satellite oriented control points were planned respectively.

Order 1 satellite oriented control points had already undergone a survey and computation phase where the standard deviation average in findings for latitude, longitude and altitude of averaged difference are ±0.3cm, ±0.6cm and ±0.2cm respectively. The survey and computation for Order 2 satellite control points will be completed within 1998.
