NLC-RSMT
|
 |
NAELCOM has produced a new Timing GPS receiver board, the “NLC-RSMT”,
which is based on the Resolution SMT high performance Timing chip set.
This OEM module is designed to provide accurate timing information.
The NLC-RSMT module is RoHS (lead free) compliant. |
- Ultra-high sensitivity of -160dBm.
- Accurate 1 PPS or even second output, synchronized to GPS or UTC within
15ns.
- Automatic self-survey.
- T-RAIM Timing Receiver Autonomous Integrity Monitoring provides high
PPS integrity.
- Low power consumption: 100mA @ 3V.
- The 2 ports that can be configured to suit the customer’s requirements
such as: input and output protocols and transmission speed.
- Supports 3V or 5V Antennas.
- TSIP and NMEA protocols.
