NAELCOM has produced a new GPS receiver board,
the “NLC-P25-A”,
which is based on the Copernicus™ high
performance GPS chip set. |
| This OEM module is designed for use in embedded and industrial applications
requiring high accuracy positioning and timing information. |
- Ultra-high sensitivity of -160dBm (-190dBw), enabling high
performance acquisition and tracking in urban canyon and signal obscured
environments.
- SBAS support (WAAS, EGNOS), for improved Horizontal and Altitude accuracy
- Cold Start Time to First Fix (TTFF) is quicker than 38s.
- Low power consumption: 37mA @ 3.3V.
- 1 port that can be configured to suit the customer’s requirements
such as: input and output protocols (NMEA, TSIP and TAIP) and transmission
speed.
- Default configuration is NMEA, 4800, 8, N, 1, GGA and VTG messages
- Configuration parameters backed-up to an EEPROM.
- Accurate pps (pulse per second signal), better than ±60 ns.
- New stationary mode for timing application
