Technical Specifications

Hardware

Server

  • Supermicro SuperServer 5017R-WRF rackmount server with 1U chassis and X9SRW-F motherboard:

    • Three 4cm counter-rotating PWM fans
    • One passive CPU heatsink
    • Two riser cards
    • Four hot-swap 3.5" drive bays (SATA)
  • Intel 1.8 GHz Quad-Core Xeon Processor
  • 8 GB RAM
  • Two Western Digital Re 500 GB Enterprise-Class Hard Drives in RAID Mirroring configuration
  • Two redundant, hot-swap power supplies, 100-240 VAC auto-switch, 50-60 Hz, 500 W each, with IEC60320 C14 inlet coupler
  • Connectivity:

GPS Receiver

  • Connector: SMA, +5V to power active antenna (SMA-to-Type-N-adapter cable included)
  • Frequency: GPS L1 (1575.42 MHz)
  • Satellite tracking: 1 to 50, T-RAIM satellite error management
  • Synchronization time:
    • Cold start < 15 minutes (includes almanac download)
    • Warm start < 5 minutes (assumes current almanac downloaded)
  • GPS Antenna system: See antenna installation guide (antenna sold separately)

Oscillator

Oscillator accuracies

  OCXO Rb
Accuracy to UTC (1 sigma locked to GPS) 50 ns 25 ns
Holdover Accuracy (loss of GPS signal after 2 weeks locked, constant temperature)
After 4 hours 1μs 0.2 μs
After 24 hours 25 μs 1μs

Notes:

• Accuracy to UTC is measured by comparing the internal 1PPS with the GPS ontime point.

• When ordering a VelaSync unit, either an OCXO or Rubidium oscillator must be specified.

• The specifications are subject to a steady environment temperature.
