Highlights

SimXona generates certified Xona Pulsar low Earth orbit (LEO) positioning, navigation, and timing (PNT) demonstration and production signals for comprehensive Assured PNT receiver testing.

Signal generation capabilities

  • Supports Xona Pulsar demonstration signal (XL) and production signals (X1, X5)
  • Generates I/Q files at 30 or 60 MHz sample rate with 16-bit depth
  • Worldwide scenario coverage within bounded timespans using Xona-provided SP3 orbital data
  • Supports both static and moving vehicle scenarios
  • Platform compatibility and integration

Compatible with PNT X and GSS7000 simulator platforms

  • On PNT X, the I/Q generator is built into the C50 X — no additional chassis required
  • For GSS7000, a standalone I/Q generator and optional signal generator extend existing systems
  • Existing GSS7000 simulators can be upgraded to produce Xona Pulsar signals alongside GNSS
  • Controlled through SimGEN software for scenario definition, I/Q task scheduling, and radio frequency (RF) simulation execution

Signal generator performance (GSS7000 extension)

  • 0.1 dB carrier level control resolution with ±0.5 dB absolute accuracy
  • Run-to-run repeatability of ±0.1 dB
  • Internal 10.00 MHz oven-controlled crystal oscillator (OCXO) with ±5 × 10⁻¹⁰ per day stability
  • N-type coax 50 Ω RF output; separate ports for GNSS and Xona Pulsar signals
  • Compliant with Xona Pulsar demonstration ICD v1.3.0 and production ICD v0.5.0
