Aerospace & Defense

Defense and aerospace projects have three specific requirements:

1. Holdover from days to months for situations where GNSS is not available (jamming, EMCON, underground installations)
2. Chain-of-custody documentation: who built, tested and calibrated the unit?
3. CE / RoHS / ITAR compliance where applicable

What we typically deliver:

• GMR5000 or GMR6000 with the Rubidium option for multi-day holdover
• Antenna installations in EMC-shielded environments
• Certificate of Conformance per individual unit, traced by serial number

Points of attention:

• No consumer-grade GPS receivers for mission-critical use. The Masterclock GNSS modules are genuine L1 multi-constellation, not smartphone-class
• Backup time distribution via IRIG-B instead of NTP for isolated-network deployments
• On-site survey: Daylight comes to measure where the antenna goes, how the cable run is laid out and which shielding fits

We do not integrate weapon systems or avionics, those are different specialists. The timing layer underneath your mission-critical network is our expertise.

Which time server do you choose for defence and mission-critical?

Defence and mission-critical networks usually need a redundant, traceable time chain: a GMR grandmaster (GMR5000/6000) with dual GNSS and long holdover, optionally Rubidium for autonomy during GPS loss or jamming. See why redundancy and holdover matter here in reliable time, and follow the NTP/PTP time server decision guide.
