Using
a Surplus Pan/Tilt HeadSatellite Tracking Rotator
This May look a little small,
but it is a very robust little unit. It is in fact a surplus Pan/Tilt head
for a large external camera housing. I have installed 10 Turn potentiometers
on each axis. The Pot's are monitored by A PIC16-622 Micro. Commands are
sent via RS485 from a PC running WinOrbit through a secondary program
I have written that uses Dynamic Data Exchange of position data
from WinOrbit
The antenna array includes:
two inclined 2m yagis which can be
phased to give left, right circular, vertical, horizontal and both inclines.
70cm Helical which uses a groundplane
from an old Galaxy pay TV antenna.
Connifer'
brand T5120 2.4Ghz down-converting pay TV antenna that is under
assesment for sat work.
As soon as the documentation is finalised the following wil be avaliable for download
1. DDE software
to control from Winorbit
2. Schematics
3 PCB Layout
(Protel and PDF)
4. Firmware for
PIC Micro, RS485 Axis controller
