Geodetic Reference Systems — Heavy Duty Points

The Deutsche Hauptschwerenetz (DHSN) contributes to the realisation of the height reference system throughout Germany and manages the official severity values. The SFPs are definitions that are physically determined, geodetically secured and measured. Their data is recorded under a point mark in the proofs of the fixed points. The proofs of the fixed points are divided into an overview of the fixed points based on the topographic map 1:25,000 (TK25) as a point signature with point number, a point description (measurement sketch) and a point file (heavy value).

德国国家重力基本网（Deutsche Hauptschwerenetz，DHSN）支撑全德国高程基准系统的建立，并负责管理官方重力值。SFPs是经物理测定、大地测量加固并实地实测得到的标定点位，其数据以点标记的形式记录于固定点检定证书内。固定点检定证书包含三类内容：基于1:25000比例尺地形图（TK25）编制的固定点概览（标注点号与点标记）、点描述（测量草图）以及点文件（重力值）。
