The Mini-VDR VDB Receiver is a small D8PSK-TDMA receiver designed to support the
monitoring and analysis of GBAS (LAAS / GBAS) ground station in the laboratory or in the
field. In addition to providing data, the Mini-VDR VDB Receiver provides RF parameters
with each GBAS message received. These RF parameters include:
- Frequency Offset
- Signal Strength
- Signal Quality
- Time Into Slot
- Actual Slot
- SSID
