First Person View (FPV)
ModalAI’s NDAA-compliant digital FPV ecosystem: ready-to-fly FPV drones and the standalone digital video link that powers them, all running the same VOXL SDK.
Blue UAS Cleared
Stinger Vision FPV
Long-range, NDAA-compliant digital FPV with onboard VIO-assisted flight. Stinger shares its core hardware and software with ModalAI's cleared government platforms — the same digital video link, autonomy services, and VOXL SDK, available to everyone.
The Digital Video Link
The VTX Air Unit and VRX Ground Unit are the standalone building blocks of ModalAI’s low-latency digital FPV link — the same link flown on Stinger.
VTX Air Unit
Digital video transmitter for VOXL-based aircraft — encodes the camera feed, composites the OSD, and ships it to the ground.
VRX Ground Unit
Ground-side receiver that feeds your goggles or ground station — pairs with the VTX for the full digital link.
AI Detection
The VTX/VRX link supports onboard AI detection — objects detected in the video feed are highlighted live in your goggles. See the AI Detection Setup Guide to enable it.
Under the Hood
FPV drones run the standard VOXL SDK — video flows through voxl-vtx and voxl-osd, ELRS RC feeds PX4 onboard, and voxl-rc-server on the VRX bridges your transmitter or a joystick over IP. See how the SDK fits together for the full interactive service diagram.
Seeker Vision (D0008 / D0020) are Blue UAS cleared platforms available to government customers. Their technical documentation is not publicly hosted — request access through the Blue UAS Cleared FPV customer intake form.
