The description says it will give more accurate runway position than a 430W (presumably with a GA-35 or GA-37). Why is it so much better?

The 430W and GTN650 output the GPS position in ARINC-429 format, the ARINC-429 resolution is only about 40 feet. Our new GPS resolution is a few feet, NMEA with 4 decimal places resolution. The 430W/650 RS-232 Aviation format is only 3 decimal places.

so to get that accuracy would you have to connect it to the serial port of the EFIS and use the internal GPS as the source? That is, I couldn't connect the antenna to my backup GPS and get the same accuracy because it's a result of the format, not the antenna?

The new GPS Antenna module is actually a GPS and Antenna in the same housing. The latest EFIS software lets you select an independent source for the system location. It will use the AF-GPS for GPS position and GTN-650 for navigation data.

If standalone, how is this interfaced to the EFIS?

rob,
will this work with the 4500?

but it still requires a serial connection to the EFIS then? I'm all out of serial ports unfortunately.

it would be really great if the GPS, ARINC module, ARHS and the transponder could all connect over ethernet. That would give those of us with only one screen a lot more options.

Currently the new GPS will only work with the AF-5000 units.

when will the 4500 upgrade to 5000 be ready?

If the screens show up in the next 10 days we will have one at Oshkosh. We should be able to start shipping them in late August.

hope you can give us 4500 guys a good deal to upgrade. the upgrade from the 3500 to the 4500 was a bit disappointing.

Any idea of the range of operating temperature for this unit? Where are suggested mountings for this - can it be placed firewall forward, under the fiberglass cowl, similar to mountings for GPS antenna only mountings?

The GPS Temperature range is -40C to +85C

I have a 4500S and would like to install a 2nd GPS. I bought the 73102 GPS module and ready to install it. I need cable end DB15 male. Wher can I buy this from?

Thanks

It depends on which RS-232 port you use, it needs to get powered from the OAT power on the DSUB-25 main connector.

Is this true of the 4500s? Isn't Pin 9 on the 4500 expansion port (DB-9) providing the 5v?

73101 needs +5V
73102 needs +8V from 5000R7 or +12V from 4500 OAT

73101 needs +5V
73102 needs +8V from 5000R7 or +12V from 4500 OAT

Does putting the GPS in parallel with the OAT sensor power impact the OAT output at all?

If the OAT on the 4500 is +12v, can I grab power directly from a VPX circuit?

Rob Hickman

You are only connecting the GPS to the +10V power for the OAT, it will not impact the OAT readings.

I'm confused by this thread. In reading other threads, it seemed that it was possible to use a Garmin 430 (non-WAAS) for nav and a separate, higher data-rate WAAS GPS 'puck' into serial port #1 for position info and faster screen updates, even for older 4500S units. Is this incorrect? Must I upgrade to a 5000 series screen to add a WAAS GPS puck for position?

Thanks,

No, I'm using it with my 4500s. I have my GTN650 connected to my PFD and the AFS GPS to my MFD. Works just fine.

Thanks, Bob; that sounds like good news. What about using both with a single screen, where the gps nav data enters via ARINC & position/screen updates come from the external puck via the serial port? (Hope I'm using correct terms...)

I don't have any experience with this set up, but if you have enough ports, I wouldn't think there would be an issue. You will need to validate with AFS. You can only have one GPS source active at any time.

Shawn McGinnis

Each EFIS is capable of using 3 data sources (GPS, NAV, or GNAV). One would be your 430 ARINC and one your GPS puck.

Excellent!
