Hear the approach. Keep the track through taxi.

BravoRelay runs on two small receivers on site that listen to aircraft transponders and report what they hear back to your dashboard. We ship them preloaded and tied to your account, so they start working the moment they have power and a network connection.

• · Two preconfigured receiver units, one mounted high and one low near the ramp
• · An outdoor antenna and coax run per receiver
• · Power and network connection per receiver

The receivers are included with the Ops and Command plans. The Ramp plan is ground ops only. There are no receivers, live radar, or hardware fees. On Ops and up, the one-time hardware & setup fee is $600 per location, and it's waived when you prepay annually or join as a design partner.

The two receivers work as a pair. The high unit sees distant traffic, and the low unit near the ramp catches the touchdown, the taxi in, and helicopters a high antenna can miss. BravoRelay merges both feeds automatically.

• High antenna = long-range warning. Roofline of the FBO or hangar is ideal for seeing enroute traffic 20+ minutes out.
• Low antenna = surface coverage. A second antenna placed near ramp level catches taxiing aircraft and helicopters that a high antenna can miss. BravoRelay merges both feeds automatically.
• Keep the coax run short. Under 25 feet if you can. Long runs cost you range.
• Vertical, outdoors, away from metal. Mount the antenna vertically and clear of large metal surfaces and other transmitters.
• Metal nearby matters even if the antenna doesn't touch it. Mounting on a metal staircase, railing, or roof edge can couple the antenna to the structure and create a null at low elevation angles. If you see strong high-altitude coverage but miss helicopters and taxiing aircraft, move the antenna off the metal or add a non-conductive spacer / mast extension.
• Indoors is a fallback. A window facing the approach still gives usable coverage for a first week while you plan the roof mount.

• · Wired Ethernet is preferred; Wi-Fi works if the signal is solid at the mount point.
• · For Wi-Fi, enter the final network in Raspberry Pi Imager before writing the card. For an installed receiver, add or change a network with nmcli.
• · Outbound HTTPS only. No inbound ports or port forwarding required.
• · No static IP needed. The receiver identifies itself with its own key.
• · Roughly a few megabytes per hour of traffic. It is not a bandwidth concern.
• · A bounded durable queue preserves unsent observations through network loss, reboot, or power loss.

Tracking runs on our servers, so arrivals and alerts keep working even when nobody has the app open.

Crew use their own phones or tablets, including iPhone, iPad, and Android. BravoRelay runs in the browser and installs like a normal app, so there's no app store, no MDM, and no device purchase required.

1. Create your organization and location.
2. Mount both antennas, connect each independently keyed receiver, and apply power.
3. Confirm both receiver status badges in Settings → Hardware.
4. Leave both units online so signed updates, watchdog recovery, and safe rollback can run remotely.
5. Invite your crew and assign roles.
6. Log your first fuel ticket. The rest follows the same pattern.
