Solving Real-World Pain Points

Why customers choose PNT-Secure 400 for civil security projects

Pain 01

Signal Interference

⚡
TX

Interference sources cause GNSS to lose lock in complex environments.

Our Solution:
  • 85 dBc interference mitigation holds lock under strong interference.
  • 360° full-space coverage blocks malicious signals.
Pain 02

Complex Integration

✖
TX

Integrators want fewer wires, less debugging, and fast deployment.

Our Solution:
  • Built-in full-frequency receiver, direct NMEA 0183 output.
  • One serial cable for positioning. Days to hours.
Pain 03

Payload Limits

10W

400g

Robotic platforms are extremely sensitive to weight, size, and power.

Our Solution:
  • 400g, 130×135×38mm, small enough for integration.
  • 10W low power, no burden on battery.
Pain 04

Differentiation

Integrators want added features but lack the ability to develop from scratch.

Our Solution:
  • Supports secondary development (spectrum, histogram).
  • One device = Protection + Positioning + Monitoring.
Pain 05

Project Acceptance

PASS

Government or enterprise projects require data and proof for acceptance.

Our Solution:
  • Interference power detection for solid data.
