ptcs -- GBT Precision Telescope Control System Project
About ptcs	English (USA)
The GBT has an ambitious program to allow effective operation at frequencies as high as 115GHz (wavelengths as short as 3mm). Although observing at such frequencies makes use of many of the same components as lower frequency operation, some additional capabilities are required. A key one of these is the Precision Telescope Control System. This is the combination of metrology systems, servos and control software which will deliver the pointing, collimation and surface accuracy required to operate the GBT at frequencies up to 115GHz (wavelengths as short as 3mm).
