Divimath Goggle

Professional Encrypted Digital and Multi-Band Analog FPV Headset

The Divimath Goggle is a professional-grade FPV headset built for pilots and integrators who require secure digital video, exceptional analog reception, ultra-low latency, and flexible operation across multiple frequency bands.

For digital operation, the goggle supports encrypted Divimath video transmission with no additional latency, helping protect the video feed against unauthorized viewing. For analog operation, its integrated high-sensitivity 5.8GHz receiver delivers industry-leading weak-signal reception without requiring an external module. The optional Analog Expansion Bay adds support for additional analog frequency bands, including 3.3GHz.

A dedicated 3.5mm PPM input allows the goggle to receive channel commands from a compatible RC controller. This enables rapid, synchronized frequency hopping with encrypted Divimath digital video, conventional analog video, and multi-band analog systems operating across frequencies such as 5.8GHz and 3.3GHz.

The result is a single NDAA-compliant headset designed to support secure digital video, integrated 5.8GHz analog, expanded analog frequency coverage, and external HDMI video sources.

Encrypted Digital Video

• Secure digital video: Supports encrypted Divimath digital video to help protect the video feed against unauthorized reception and viewing.
• No added encryption latency: Video encryption does not increase the system's ultra-low latency.
• Mission-focused operation: Designed for government, defense, commercial, and other applications where an openly viewable video feed is unacceptable.
• Ultra-low-latency digital video: Less than 3ms glass-to-glass latency, depending on the selected video mode.
• Encrypted frequency hopping: Rapid channel changes can be used while operating an encrypted Divimath digital video link.
• Built-in digital DVR: Record received Divimath digital video using the integrated H.264 DVR.

Industry-Leading Analog Video Support

• Integrated high-sensitivity 5.8GHz analog receiver: Excellent weak-signal reception and clear analog video without requiring an external receiver module.
• Optional Analog Expansion Bay: Add a compatible analog receiver module for additional frequency bands, including 3.3GHz.
• Multi-band analog operation: Use the integrated 5.8GHz receiver together with an expansion receiver for operation across multiple analog frequency bands.
• Ultra-low-latency analog processing: Less than 2ms latency through the integrated deinterlacer.
• Analog DVR recording: Record received analog video directly using the built-in H.264 DVR.
• Rapid analog startup: Access the integrated analog receiver within seconds of powering on the headset.
• Advanced analog controls: Supports multiple analog bands, automatic scanning, loop scanning, selectable aspect ratios, and configurable analog display modes.

RC-Controlled Rapid Frequency Hopping

• 3.5mm PPM control input: Connect the goggle to a compatible RC controller or transmitter using a 3.5mm PPM cable.
• Synchronized channel changes: The aircraft video transmitter and goggle receiver can follow the same RC switch command, keeping both ends of the video link on the selected channel.
• Encrypted digital frequency hopping: Rapidly change between configured Divimath digital channels while maintaining digital video encryption.
• Analog frequency hopping: Rapidly change between configured analog channels using the integrated receiver.
• Multi-band analog hopping: Switch between frequency bands such as 5.8GHz and 3.3GHz when the optional Analog Expansion Bay and a compatible receiver module are installed.
• Flexible RC integration: Video channel selection can be assigned to a switch or other control on a compatible RC transmitter.

Frequency-hopping operation requires compatible aircraft-side video transmitter control, RC configuration, and supported receiver hardware. Multi-band analog operation requires the optional Analog Expansion Bay and a compatible analog receiver module.

Key Differentiators

• Encrypted Divimath digital video: Helps protect the digital video feed against unauthorized viewing without adding latency.

Compliance and Origin

NDAA compliant
Country of Origin: Thailand

The Divimath Goggle is designed for pilots and integrators who require secure digital video, dependable analog reception, and flexible multi-band operation. Its encrypted digital video support, integrated high-sensitivity analog receiver, optional analog expansion, and RC-controlled rapid frequency hopping make it particularly well suited to mixed-system deployments where Divimath digital video, 5.8GHz analog, 3.3GHz analog, and HDMI sources must operate through one professional headset.
