Overview
Long-range drone command-and-control and video/data links depend on directional antenna hardware — often mounted on an automatic tracking positioner that keeps a high-gain beam pointed at a moving aircraft — to achieve range and reliability well beyond what a fixed omnidirectional antenna can provide. This subsection covers the antenna and tracking-positioner hardware layer specifically, distinct from the Communications section’s coverage of the radio modules and waveforms those antennas carry, and distinct from Flight Controllers / Autopilot Hardware, which covers the onboard computer rather than the RF link hardware.
Key Themes
- Auto-tracking ground antennas (mechanically steered high-gain directional antennas that follow the aircraft) are what extend practical UAS command-and-control range from tens of kilometers to 60+ km, and are a distinct hardware category from the radio/waveform layer that rides on top of them.
- Radio-agnostic tracking antenna platforms — supporting COFDM, OFDM, CDL, and MIMO/MANET waveforms interchangeably — are a deliberate design choice among defense-market suppliers, letting customers swap radio modules without replacing the antenna and tracking mechanism.
- Both named companies in this entry emphasize operation in GPS-denied and RF-contested (jamming) environments as a core design requirement, reflecting the shift toward electronic-warfare-resilient design driven by recent conflict experience (echoing themes already noted in Flight Controllers regarding Ukraine-driven procurement shifts).
- Platform OEMs (e.g., AeroVironment) that build their own tracking antennas for their own aircraft (e.g., Puma AE) differ in value-chain position from independent tracking-antenna specialists (e.g., Troll Systems) that sell radio-agnostic ground equipment across multiple aircraft platforms and customers.

Supply Chain
Supply Chain Layers
| Layer | Key Inputs / Outputs | Companies Operating Here | Geographic Risk |
|---|---|---|---|
| 1. Antenna/RF hardware design | Directional antenna elements, radomes, pan/tilt tracking positioners | Troll Systems, AeroVironment (in-house for its own platforms) | US-concentrated for both named suppliers |
| 2. Tracking and acquisition software/electronics | Auto-alignment, calibration, acquisition, and tracking algorithms; embedded INS/dual-GPS positioning | Troll Systems (patented RF acquisition/tracking software) | Proprietary, vendor-specific — not a shared/commodity toolchain |
| 3. Radio/waveform layer | COFDM, OFDM, CDL, MIMO/MANET transceivers riding on the antenna hardware | See Communications | N/A — adjacent layer, not duplicated here |
| 4. Aircraft/ground-station integration | Complete C2/video link between aircraft and operator | AeroVironment (platform OEM, vertically integrated); Troll Systems customers (integrator/platform-agnostic model) | N/A — integration layer |
Key Supply Chain Notes
Platform OEM vertical integration vs. independent tracking-antenna specialist: AeroVironment builds its LRTA and ERA tracking antennas specifically for its own Puma AE and related aircraft, a vertically integrated model similar to patterns seen elsewhere in this research area (e.g., DJI’s closed gimbal-camera-drone bundle, see Gimbals & Camera Stabilization). Troll Systems instead sells radio-agnostic tracking antennas across multiple aircraft platforms and customer types (UAS, law enforcement, broadcast), a model closer to Gremsy’s independent-supplier position in the gimbal market.
GPS-denied operation as a shared design requirement: Both named companies explicitly market GPS-denial resilience (embedded INS, dual-GPS, auto-calibration without relying solely on satellite positioning) as a core capability — a direct response to the same electronic-warfare and jamming environment that has driven procurement changes noted in Flight Controllers (Blue UAS Framework) and broader defense-market UAS trends.
