GNSS antenna engineering, built for the long term
Our factory specializes in GNSS antenna and resilient navigation solutions. Our offering is focused on lawful civil and commercial applications, including unmanned platforms, autonomous systems, maritime operations, surveying, and other high-precision positioning scenarios. We are committed to practical engineering, reliable delivery, and responsible supply for international customers.
An independent brand
Navifort is an independent brand operated by RedSun (HK) Group Limited. We present our own products, documentation and commercial terms directly to international customers.
Practical engineering
We design for the platform, not the spec sheet. Every unit is validated against the mounting, mass and environmental limits our customers actually work within.
Responsible supply
Our offering is focused on lawful civil and commercial applications. Enquiries are reviewed for end use before detailed documentation is released.
Certified systems
Our quality, environmental and occupational health and safety management systems are independently certified to ISO 9001, ISO 14001 and ISO 45001.
Our R&D journey
We are a manufacturer with proprietary technology and independently developed patents. The outline below covers how the product line developed; detailed performance characteristics are shared following project review.
- 2014Research programme begins
In-house research into resilient GNSS reception starts, with the first-generation signal-processing algorithm completed in January 2015.
- 2016Second-generation platform
A second-generation product platform enters production, improving reception stability across a wider range of operating conditions.
- TodayOwn algorithm and receiver
We develop our own signal-processing algorithms and navigation receiver, and offer both baseband-chip and FPGA-based solutions for lightweight, highly integrated designs.
- 2026Anti-spoofing units
A new generation of integrated anti-jamming and anti-spoofing antenna units joins the range.
Controlled Reception Pattern Antennas built around a compact, full-band design for civil unmanned platforms and high-precision positioning work.
Higher-end integrated units that combine reception with signal-integrity processing for demanding civil and commercial deployments.
