Rohde & Schwarz Adds Pulsar Signal Simulation for LEO Navigation

Why It Matters

By enabling early, repeatable testing of LEO‑based signals, manufacturers can lower development risk and accelerate deployment of more resilient positioning systems, a critical need as GNSS faces increasing jamming and spoofing threats.

Key Takeaways

• Rohde & Schwarz adds Pulsar simulation to SMBV100B and SMW200A generators.
• Enables manufacturers to test LEO navigation receivers before Xona’s constellation launch.
• Supports multi‑constellation, interference‑resilient designs for automotive and aerospace.
• Reduces development risk by providing repeatable test environments for new signals.
• Part of Pulsar verified ecosystem, ensuring compatibility across test equipment.

Pulse Analysis

The launch of Xona’s Pulsar constellation marks a pivotal shift toward low‑Earth‑orbit navigation, promising stronger signals and higher accuracy than traditional GNSS. While GPS and other legacy systems remain the backbone of global positioning, the industry is increasingly looking for complementary LEO services to mitigate vulnerabilities such as jamming, spoofing, and signal blockage in urban canyons. Pulsar’s design to coexist with existing GNSS constellations makes it an attractive option for sectors that cannot afford downtime, including autonomous vehicles, aerospace platforms, and critical infrastructure monitoring.

Rohde & Schwarz’s decision to embed Pulsar signal simulation into its SMBV100B and SMW200A vector signal generators addresses a clear gap in the test‑and‑measurement market. Engineers now have a software‑based method to generate authentic Pulsar waveforms, enabling them to verify receiver performance, assess interference tolerance, and fine‑tune firmware long before the satellite network is fully operational. This capability shortens the validation cycle, reduces costly hardware iterations, and provides a repeatable environment that aligns with industry standards for multi‑constellation testing.

Looking ahead, the integration signals broader industry momentum toward a diversified navigation ecosystem. As more LEO constellations emerge, test equipment vendors will play a critical role in ensuring interoperability and resilience across the supply chain. Rohde & Schwarz’s participation in the Pulsar verified ecosystem not only strengthens its portfolio but also sets a benchmark for how test solutions can accelerate the adoption of next‑generation positioning technologies, ultimately delivering more reliable services to end‑users worldwide.
