The Calian TW162A is an automotive-grade, full GNSS band Smart Power signal splitter that connects one antenna to two receivers. It supports a wide range of GNSS signals, including GPS/QZSS-L1/L2/L5, QZSS-L6, GLONASS-G1/G2/G3, BeiDou-B1/B2/B2a/B3, Galileo-E1/E5a/E5b/E6, NavIC-L5, and L-Band correction services.
Key Considerations
GNSS is a critical component in autonomous and automotive vehicle applications, requiring very high availability. Resilient, fault-tolerant components are essential to avoid service interruptions. The Calian TW162A is designed with AEC-Q100-certified components, ensuring reliable operation under extreme temperature conditions.
Features
Smart Power Selection
- Accepts power from all connected GNSS receivers.
- Prioritizes Port #1 if its voltage is within the specified range (3.0 – 12.5 VDC).
- Switches to the next port in numerical order if Port #1 is disconnected or its power is out of range, ensuring deterministic switching and port selection.
Antenna Fault Detection
- Provides all connectors with a current draw lower than 1 mA if the antenna fails, indicating an antenna fault.
Specifications
- Connectors: Available with FAKRA connectors (3x Z or A+B+C).
- Gain: Standard gain to compensate for signal-splitting loss.
