NMEA/PPS Source- with Selectable Timing Sources GNSS, Serial Data or OCXO Holdover

NMEA-PPS Master Timing Source with Prioritize Timing Source


The NP3001 accepts timing information from either an embedded GNSS receiver or an external NMEA/PPS source. Each source can be prioritized. Once synchronized the unit will produce NMEA and PPS from the selected source. If all sources fail, the unit becomes a simulator based upon its internal OCXO. Battery backup allows the unit to be synchronized and then used to bring timing information into a GNSS denied environment. Front panel display provides equipment status and facilitates the equipment configuration. The 26 Channel GNSS receiver quickly acquires and can be programmed to produce a PPS pulse once an accuracy level has been achieved or to produce a PPS from a TCXO source continuously. NMEA data streams can be programmed to content and baud rates. The unit may also be powered from a DC source or a Novus power adapter.

  • GNSS lock indicator and built in self test
  • PPS accuracy 15 ns @ 1 sigma.
  • 26 Channel GNSS receiver
  • PPS pulse programmable in 1 ms increments.
  • Cable delay compensation
  • Operates from DC Power in three ranges +- (10 to 18, 18 to 36, 36 to 65) VDC or an AC Adapter
  • Accepts timing from the GNSS receiver or an external NMEA/PPS source

    Kits are available that include antenna, cables and power supply. Several features can be customized at the factory – frequencies other than 10 MHz either from a unique crystal or with a built-in synthesizer that is GNSS-locked. Time stamping capability to 100ns resolution. To meet unique requirements, we have shipped product with output features requiring a custom amplitude, square wave output, high voltage and high current drive.
