Links de Interés - Proyectos Especiales (En Inglés)

The ARS is not only used for Hams. Also several Telecom Universities, Telecom companies, TVRO and Radio-Astronomy fans are using it.

Recently, I was sharing a project with a telecom company, and this was the history:

SATTRACK

An Spanish Telecom Company contacted with me for using the Antenna Rotator System for an special project. The would like to devellope a system to be mounted at vehicles (wagons, bus, trucks) and when they park at any place, the system will appoint a Dish antenna towards a Geostationary Satellite (Astra, Hispasat, ...) for Data Link comunication between the vehicle and the Central Office (SDLC or X.25 protocol)
So they would like to use 2 rotators (Azimuth & Elevation) with a computer interface to handle the Dish Antenna. After several meetings they purpose to me to devellope all the system.
I started the software & hardware project (SatTrack) and besides the ARS I used:

  • GPS with a serial interface to know the park long, latitud, altitude & magnetic offset
  • Magnetic Compass with serial interface to know the vehicle position
  • Digital Tuner for reading the Satellite signal (dB) for fine tunning
  • Pro.Sis.Tel rotator PST71 for Azimuth movement.
  • Dish positioner Actuator for Elevation movement

After several months working at the project, it was finished. It really works fine!!
I was managed for looking for the metallic structure (iron/aluminium), rotators, actuators, ...

This is the final project aspect..... Enjoy it!
