LXNAV ADS-B Receiver

A practical standalone ADS-B 1090 IN solution. ADS-B receiver listens to ADS-B 1090 transmitters. Data can be displayed to any standard remote traffic display via the output port in FLARM standard NMEA format.

There are many low-cost ADS-B 1090 and UAT receivers on the market. However, they don't send traffic information in the soaring standard FLARM format, so they don't work with soaring instruments. This device does send traffic information in the standard FLARM format, so it works great for sending ADS-B 1090 traffic to any standard FLARM remote display or soaring instrument - like an LXNAV S8, S80, S10, S100, LX80x0, or LX90x0.

Does not receive or transmit FLARM traffic data. It is not recommended for sailplanes that fly in areas with other sailplanes. Most sailplanes that fly in soaring contests use PowerFLARM units.

The ADS-B Receiver not include a GPS engine or GPS antenna. GPS data is required.

An LXNAV GPSMouse could be used to send GPS data to the ADS-B Receiver's input port. However, the GPSMouse has a 6-pin RJ12 connector and the ADS-B Receiver's input port is an 8-pin RJ45 port. The GPSMouse uses "IGC Standard" wiring, so a simple adapter cable could be used, or an 8-pin connector could be put onto the GPSMouse's cable. A standard FLARM display cable like the LXNAV-FlarmViewPF-CA could be used along with a 6-pin RJ12 coupler. Since the GPSMouse needs 12V power, and the ADS-B Receiver needs 12V power, an LXNAV-Splitter-PF-RJ45 would be needed to be allow the connection of a 12V RJ45 power cable (included).

A "Classic" FLARM without ADS-B could be used to send GPS data to the ADS-B Receiver. The ADS-B Receiver would forward FLARM traffic to the connected traffic display.

Normal Operation
The ADS-B receiver goes into normal operating mode when it receives signals from enough GPS satellites.

How the system works
The ADS-B receiver can listen for 1090 MHz transponder data (Mode S and ES). Received data will be transmitted to the output port in FLARM standard NMEA format. The ADS-B receiver will operate only if it receives GPS data in its input port. GPS data must be standard NMEA format. The ADS-B receiver will automatically detect the baudrate on input port and transmit NMEA data on output port at the same baudrate.

Features

Receives ADS-B 1090 traffic and forwards it to a connected traffic display
May also receive relayed ADS-R (ADS-B UAT) traffic if you have ADS-B OUT and are near a radar ground station. This feature should work, but the manufacturer is in Europe and ADS-B UAT isn't used in Europe - so it isn't fully tested.
Works with all standard FLARM displays (3V and 12V)
