For precise timing we use the Trimble Acutime Gold GPS smart antenna. It generates a pulse-per-second (PPS) output synchronized to UTC within 15 nanoseconds, outputting a timing and position packet for each pulse.
| Key features of the Acutime Gold: | |
| Accuracy: | UTC 15 nanoseconds (static) |
| Resolution: | 80 nanoseconds |
| PPs (puls per second output): | 10 microseconds to 500 milliseconds (user-programmable) |
| Interface: | Serial RS422/485 or RS232 (cable length up to 300 meter) |
| Serial protocols: | TSIP, NMEA or RTCM protocols |
| Prime power: | +5V DC to +36 V DC |
| Power consumption: | 50mA @ 12 Volts, 0.6Watt (typical) |
| Housing: | Waterproof, pole mounting |
