Precision GNSS, RTK & Timing Solutions — Engineered Wherever Precision Matters
GNSS satellites carry atomic clocks, which makes them the most practical source of accurate, traceable time almost anywhere with a view of the sky.
Navisys turns that signal into the outputs equipment actually uses: a 1PPS pulse marking the start of each second, and a disciplined 10MHz frequency reference — as a rackmount unit, or as an engine board to build into your own product. See the timing and synchronization page for where these are used.
A pulse on every second boundary. Servers and instruments use its rising edge to align their own clocks; the accuracy figure tells you how close that edge is to true UTC.
A frequency reference disciplined to GNSS. Radios, test equipment and oscillators lock to it so their timebase does not drift.
How long the output stays within specification after the antenna loses sky view. Four hours within ±1.5µs means a rack keeps serving usable time through a long outage.
The receiver first averages its own position, then holds it fixed. With position known, all of its effort goes into solving time rather than location.
