[QUOTE="s-band, post: 1150795, member: 407744"] Originally I fitted pulse encoders to the Pelco P&T to use with an RC2000. The motors are 110VAC so I use a variable frequency source (10-60Hz with a 500W audio module) to control the speed. I added an absolute encoder and an inclinometer to use with an [URL="https://www.f1ehn.org"]EME System - F1EHN[/URL] controller. The ephemeris data comes from [URL="https://ssd.jpl.nasa.gov/horizons/"]Horizons System[/URL] The F1EHN controller drives the RC2000 but only because I haven't got around to re-configuring the motor switching form +/-36V to 5V logic. The F1EHN will also take DDE data from [URL="https://www.satsignal.eu/software/wxtrack.htm"]WXtrack - predicts satellite positions and ground path images - from David Taylor, Edinburgh[/URL] for Earth orbiters. WXTrack is a bit flakey interpreting some geostationary TLEs which is a pain. Picture shows the Pelco and dish during development. [ATTACH]151281[/ATTACH] [/QUOTE]
