NLC101-232
Ruggedized
Low Power
Navigation module

Introduction

The NLC101 has been designed to provide accurate and reliable navigation information trough a RS-232 or RS-422 link.
Based on a high performance GPS chip, it delivers accurate position information, even in poor signal level environments (tree foliage, urban canyons).

Performance

Ultra-high sensitivity of -160dBm, enabling high performance acquisition and tracking in urban canyon and signal obscured environments.
Time to get first fix information is around 38s (cold start).
RS232 or RS422 serial port can be accessed for monitoring and control : NMEA and Trimble TSIP & TAIP protocol.
Highly accurate pps (pulse per second) signal (±60ns) available on SUB-D9 front panel. RS232, RS422 or TTL level.
Active antenna is voltage selectable : 3.3V or 5V (patent pending).
Optional Back-up capacitor with an autonomy of 30 hours for hot start-up after a power cut.

Protection

Metal housing, ruggedized and compact.
RS232/RS422 port is 15kV ESD protected + 60V fault protected
Protection against short circuit and over-voltage on the antenna.
Robust power supply, protected against transients and reverse polarity.

Compliance

Connectors are compliant with automotive standards.
The NLC101-232 module has successfully completed compliance testing in accordance with the directive.
