Standard configuration of all HPS Mounts from 11/2015
The GM 4000 HPS reaches a Satellite tracking and positioning speed from 5 degrees / sek. with an average positioning accuracy <20" and a tracking accuracy of approx. 1"/15min (peak to peak).
The GM 4000 HPS disposes, in addition, of high-precision Absolut-Encoders on both axes which opens absolutely new possibilities. The mount never loses its orientation, even if one axis is shifted by hand. Also after a power failure no new Alignment is necessary. In the mobile company the mount is quicker and easier to instal and to align than any conventional equatorial mount.
The following image shows a direct size comparison between the GM 2000 HPS and the GM 4000 HPS.
Maximum payload: 150 kg of pure instrument weight (counterweights are to be attached in required number, in addition) Optimum payload: 125 kg of instrument weight (counterweights are to be attached in required number, in addition)
