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.
