4ePB Hardware Setup
2RU 19-inch rack-mountable system integrating FPGA processing and transceivers to combine multi-antenna signals.
Key Features & Performance
The Four element Power Booster (4ePB) coherently combines RF signals from four smaller antennas, achieving the performance equivalent of a significantly larger single dish.
Coherent Signal Combining
Coherently combines signals from 4 small antennas.
SNR Gain Improvement
Provides >5 dB improvement in SNR compared to that obtained with a single small antenna.
Large Antenna Equivalence
Performance of four 60 cm antennas using 4ePB is similar to a 1 m antenna.
Target Applications
Engineered specifically for Maritime and Aeronautical mobile communications.
Hardware Architecture
Built with state-of-the-art FPGA and transceiver components.
Form Factor & Control
Size: 2RU, 19” wide enclosure with IP-based monitoring and control.
Advantages of Multiple Smaller Antennas
- Reduces required tracking accuracy, simplifying tracking mechanisms.
- Easier to transport and install small antennas compared to a single large dish.
- Provides continuous coverage in scenarios where some antennas are shadowed or shaded.
- Provides enhanced Adjacent Satellite Interference (ASI) suppression.
Management & System Software
- IP-based monitoring and control interface.
- Extensive data logging capabilities for post-mission and live performance analysis.
- Separate dedicated Web GUIs for Admin and Operator interface roles.
