Timing, inside Connectivity: precision Time Protocol, telecom profile with full timing support, telecom profile with partial timing support, frequency synchronisation profile and more. Every item is traced to its specification, from IEEE 1588-2019 to ITU-T G.8275.1, and runs on the open Observatory Protocol.

01What it is
Packet timing: PTP, SyncE and NTP.
The shared foundations every network and sensor depends on: how spectrum is licensed, shared and monitored, GNSS positioning and its corrections, packet timing with PTP and SyncE, grandmasters and holdover, resilient PNT alternatives, and the detection of interference, jamming and spoofing. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
Spectrum, timing and PNT
Telecom profile with full timing support
Every node a boundary or transparent clock, for the phase accuracy TDD and Open RAN need.
We design, integrate and operate.

Spectrum, timing and PNT
Telecom profile with partial timing support
Timing over networks that do not support PTP in every node, often with local GNSS assist.
We design, integrate and operate.
