GNSS System Development — Built in Shenzhen, Deployed Worldwide.

Shenzhen Sunon Electronics Technology Co., Ltd. was founded in 2016 in Shenzhen Bao‘an District. We are an R&D‑driven manufacturer specializing in GNSS anti‑jamming modules for UAV and unmanned system applications.

Our focus is narrow by design. We don‘t build everything — we build one thing well: navigation protection for platforms that cannot afford to lose signal.

From our in‑house engineering team to our production line, every stage of development is controlled under one roof. This allows us to respond quickly to customer requirements and maintain consistent quality across every unit shipped.

What sets us apart:

- Dedicated R&D team with deep expertise in RF and GNSS signal processing

- In‑house manufacturing — full control from design to delivery

- Customization as standard — we tailor solutions to specific platform requirements

Technology Focus

The engineering focus is on three priorities:

Size and weight — compact form factors that integrate easily into UAV platforms without compromising payload capacity

Environmental resilience — reliable operation across extreme temperatures from -45°C to 70°C

Effective interference rejection — dual‑band protection that maintains navigation integrity even under active signal disruption

We design and manufacture dual‑band, multi‑channel GNSS anti‑jamming modules that protect against both signal jamming and spoofing.

Our modules cover the core frequencies used by modern UAV platforms — BDS B1, GPS L1/L5, and Galileo E1 — ensuring compatibility with widely deployed navigation systems.

Our anti‑jamming modules are deployed in scenarios where navigation reliability is non‑negotiable:

UAV operations in GNSS‑contested environments

Critical infrastructure inspection and monitoring

Border security and surveillance missions

VIP protection and event security

Platforms requiring redundant navigation protection

We work directly with system integrators, drone manufacturers, and security operators to deliver hardware that performs in the field — not just on paper.
