    Not always seeing ADS-B rebroadcast traffic

    The “breakdown” isn’t with the TIS-B rebroadcast (or rather broadcast), but the breakdown of the air-to-air reception of the 978 UAT ADS-B Out transmission. Since you are UAT IN ADS-B equipped, and have broadcast that status to the ground station via the UAT IN capability status bit, the ground...

    Not always seeing ADS-B rebroadcast traffic

    As @denverpilot said, check or ADS-B In equipage bits in the transponder. Your FAA Operation Summary will show the ADS-B emitter's reported ADS-B receive capability. With a single band ADS-B receiver you will need the bit set for that band. (UAT In for a 978 MHz receiver.) If no bits are set...

    Need Help Troubleshooting Garming GDL 39 3D Unit

    A matter of semantics. In general terms it is a "request". If the ground station does not receive the UTI / ESI bit in the DF 17 message, i.e. a "request" from the ADS-B Out aircraft, it will not respond with TIS-B / ADS-R broadcast. For 1090ES aircraft reference "Capability Class" in DO-260B...

    Need Help Troubleshooting Garming GDL 39 3D Unit

    On this, we are going to have to disagree. The performance plots for a ground station antenna supplier shows their maximum gain at 0 degrees vertical. The gain decreases 3 dB at approximately +/-20 degrees from vertical while decreasing 3 dB further approximately +/- 45 degrees from vertical...

    Need Help Troubleshooting Garming GDL 39 3D Unit

    As stated above, when setting on the ground (or in the air for that matter), the traffic information can be received directly as 1090 ES or 978 UAT ADS-B Out squitters from the airborne ADS-B emitters (transmitter). The traffic information is also received as TIS-B / ADS-R data via the Ground...

    The ADS-B signals are line of sight. With the dual band unit, you will see air-to-air ADS-B Out. To see TIS-B / ADS-R, or FIS-B, you will need to be within 5 - 10 miles of the tower when on the ground. The tower antennas are designed to point the signal skyward to cover their respective...

    uAvionix Skybeacon update...

    To me, it sounds like the FAA isn't going to allow ADS-B Out via NORSEE so now they have to TSO it as an ADS-B Out device.

    Question about gma 340 and kx 155 install

    The "P" is for twisted pair. It comes from the IEEE Std 315-1975 spec. Shield both ends. The double end shielding and the twisted pair cable provided the noise immunity required for the low level / high impedance signal between the Nav/Com and the indicator.

    Anyone been to Deland for food?

    Airport Bar and Grill. We "lived" there when a coworker and I were in DeLand on an extended assignment a few years ago. They had good food, good beer, and great live music.
