ZaiNar sub-nanosecond PNT backup

This points to a much bigger market than indoor positioning, because resilient timing is sold into critical infrastructure budgets where losing sync can shut down networks, trading systems, and industrial control loops. ZaiNar is not just locating robots or forklifts. It is using the same terrestrial radio layer to distribute precise time when GPS is jammed, spoofed, or unavailable, which makes its system relevant to telecom, power, defense, and data center operators.1 2 3 4

• ZaiNar says its system delivers sub-nanosecond time synchronization over existing cellular and WiFi networks, and frames that as immediately available terrestrial backup. That matters because many backup timing systems depend on new fiber builds, special towers, or dedicated radio infrastructure, which slows deployment and raises cost.1 5 6
• The market need is real and already recognized by governments. U.S. transportation agencies, NIST, and European regulators have all treated complementary and alternative PNT as necessary because GPS disruption can hit communications, energy, transport, and public safety systems. ZaiNar fits that demand from the terrestrial side.2 3 4 7
• Comparable approaches show the performance ladder. NextNav demonstrated terrestrial backup timing better than 50 nanoseconds in a DHS trial, while fiber based high accuracy time transfer and DARPA clock programs target sub-nanosecond or GPS level holdover. ZaiNar sits in the most ambitious tier if it can operationalize that precision at scale over ambient wireless networks.6 5 8 9

The path forward is clear. If ZaiNar can turn timing from a feature into a certified resilient service, it can move from site by site positioning deals into national infrastructure programs and defense grade PNT budgets. That would make its network less like a sensor product and more like a new terrestrial utility for time.1 2 3 4 6
