Beijing, China – June 28, 2026 – As unauthorized Starlink terminals proliferate in conflict zones and around sensitive sites, BNT has reached a significant technical milestone. The company’s flagship electromagnetic security solution, the BNTSLJ600 Starlink Jamming System, has officially passed certification by China’s National Radio Monitoring Center Testing Center (SRMC). The approval validates the system’s power, precision, and spectral agility, giving defense integrators a fully compliant counter-satellite-terminal capability.
Closing the Ku-Band Downlink Vulnerability
Starlink user equipment relies on the 10.95–12.75 GHz downlink for command, control, and data exfiltration. Legacy barrage jammers fail against these frequency-hopping, spread-spectrum signals—and their unfocused noise often interferes with friendly communications. The BNTSLJ600 was purpose-built to solve this. It delivers high-power, configurable jamming that denies the Starlink downlink while preserving spectral awareness for the operator. During SRMC evaluation, the system demonstrated consistent output and spectral control across all mandated test scenarios.
Certified Performance at a Glance
The SRMC certification process scrutinized frequency accuracy, spurious emissions, instantaneous bandwidth, and multi-target capability. The table below captures the core specifications that earned the BNTSLJ600 its certification.
| Parameter | Certified Value |
|---|---|
| Jamming Frequency Band | 10.95 – 12.75 GHz |
| Instantaneous Bandwidth | ≥500 MHz (configurable) |
| Simultaneous Jamming Frequencies | ≥8 |
| Equivalent Radiated Power (500 MHz BW) | ≥60 dBW |
| Frequency Targeting Error | ≤1 kHz |
| Jamming Modes | Narrowband, Wideband, Comb Spectrum |
| Jamming Waveforms | Noise FM, Pseudo-random (2FSK, MSK, BPSK, QPSK, OFDM) |
| Comb Spectrum Lines | 1 – 100 (center frequency & width settable) |
| Control Interfaces | Ethernet, RS-485 |
Why a Single Kilohertz Matters
In electronic warfare, power without precision is just noise. A starlink jamming system that misses the target by a few kilohertz wastes wattage and risks collateral disruption. The BNTSLJ600’s ≤1 kHz frequency targeting error ensures that every fraction of its 60 dBW effective radiated power lands squarely on the intended Starlink downlink segment. This pinpoint accuracy preserves adjacent friendly services while maximizing standoff range—field trials confirmed effective disruption at multi-kilometer distances, even when terminals attempted antenna repointing.
Multi-Carrier and Comb-Spectrum Agility
Modern Starlink terminals can aggregate multiple carriers simultaneously. The BNTSLJ600 counters this with a minimum of eight concurrent jamming channels. Beyond discrete frequency targeting, the system’s integrated comb spectrum generator places up to 100 individually tunable spectral lines across the full 500 MHz instantaneous bandwidth. This allows a single unit to blanket entire sub-bands with comb-spectrum interference while simultaneously executing narrowband attacks on known emitters—a level of flexibility that traditional single-mode jammers simply cannot offer.
Deployment Architecture and Integration
The BNTSLJ600 is built for operational environments where downtime is unacceptable. It accepts control via standard IP and serial interfaces, slotting directly into existing C4ISR and EMSEC frameworks. Security teams can remotely adjust jamming patterns, power levels, and frequency masks from a command center or vehicle. When paired with a passive Starlink Detection System, the jammer completes a detect-and-disrupt kill chain without ever revealing the defender’s position. Border security agencies and military units are already evaluating the system for fixed-site, vehicle-mounted, and mast-deployed configurations.
BNT’s Director, Ms. Yang Ying, commented: “The SRMC certification is a definitive assurance to our customers. It proves that the BNTSLJ600 doesn’t just look powerful on a spec sheet—it has been rigorously validated by the national authority. For operators facing real electromagnetic threats, that validation is everything.”
From National Certification to Global Deployment
With SRMC certification now secured, BNT is accelerating production to meet demand from domestic critical infrastructure, border security, and defense clients. The company also plans to pursue CE and FCC certifications, paving the way for the BNTSLJ600 to serve international partners facing similar Starlink-borne security challenges. Early pilot programs at multiple Chinese border checkpoints and energy facilities have already confirmed the system’s ability to force unauthorized terminals into failsafe modes, cutting illicit satellite links without disrupting authorized communications.
As satellite-enabled threats evolve, BNT continues to invest in the waveform agility and raw power that modern electromagnetic security demands. The SRMC-certified BNTSLJ600 now stands as the company’s leading answer to the Ku-band challenge—a tool that doesn’t just participate in spectrum control, but decisively seizes it.
