VigilArc SL — solver of the VigilArc LBL navigation system Device specification |
KEY FEATURES
- Position calculation from ranges to beacons with known coordinates
- Storage of beacon coordinates (up to 4)
- GNSS protocol emulation (GGA, RMC, MTW) for the data consumer
- Communication with VigilArc LX over 3.3 V UART
- Compact board that can be placed underwater or on the surface
- Configuration via the PAZM protocol
DESCRIPTION
VigilArc SL is the computing module (solver) of the long baseline navigation system VigilArc LBL.
The module receives over UART the measured range data from the VigilArc LX transceiver, stores the coordinates of the VigilArc Tag responder-beacons and calculates its own position. The result is output to the data consumer in the form of standard GNSS sentences (GGA, RMC, MTW), which allows VigilArc SL to be used as a “transparent” replacement for a GNSS receiver in existing systems.
The module can be placed either underwater or on the surface, depending on the task to be solved.
