Heavy duty points

The Gravity Reference System is implemented by the SFPs of the Federal Republic of Germany’s Gravity Base Network as well as the Heavy Duty Networks 1-4. Order with the associated severity values.These gravity points are marketed permanently in the locality. Their severity values are determined by coordinates and heights. For the geodetic fixed points, the following evidence is provided or data provided:- Overview of the fixed point field on sheets of the topographic map (fixed point overview); — Description of the fixed points with a topographical map for visiting the site (fixed point description); — File of fixed points (expression, floppy disk) with location coordinates, heights, gravity acceleration, etc.; — GPS reference station measurement data in the formats RINEX, RTCM 2.1 (20,21) In addition to the proof of fixed points, network images are presented as overviews of the network system and gravimetric maps at a scale of 1:200,000. These cards are issued as a copy only on request if justified.本重力参考系统由德意志联邦共和国重力基准网以及重型基准网1-4的SFPs搭建实现，各测点按关联的重力参数值进行排序。这些重力测点永久布设于对应区域，其重力值由测点坐标与高程共同确定。针对大地测量固定测点，可提供以下证明材料与数据：- 印制于地形图纸的固定测点场概览（固定测点概览图）；- 用于现场踏勘、附带地形图的固定测点说明文档（固定测点说明）；- 存储有测点坐标、高程、重力加速度等信息的固定测点文件（含数据表述、磁盘介质）；- 格式为RINEX、RTCM 2.1（版本号20、21）的GPS基准站测量数据。除固定测点相关证明资料外，还提供基准网系统概览影像以及比例尺为1:200000的重力测量图。上述图件仅在申请人提出申请且理由充分的情况下，方可提供副本。
