- Also available in a larger case, encompassing dish & feed cables, with room for a laptop or PDA
- Ideal as a surveillance antenna system, tracking and SIGINT
- Can be used for many other signal collection/tracking purposes
- Many different types of control can be utilised, including PDA/handheld terminal, laptop, fibre-optic interface and PC
- Variable scan, sector scan, etc. are available with an optional GUI, or can be programmed by the user
- Can take up to a 0.6m (2ft) dish for antennas up to and including millimetre-wave
- Other feeds, including RHCP & LHCP, and different reflector sizes can provided
Positional Controller
An embedded controller unit is used for each axis. The positioner’s axes are controlled via a single RS232 connection. The positioner can be controlled most simply by a computer terminal (not supplied) sending single commands for variable speed, sector scan, etc. Alternatively, we can provide a user-friendly generic graphical user interface and controller application based on a Windows 2000/XP/Vista/7 environment for more convenient control. For other operating systems please contact us and we will be happy to discuss your requirements.
