THEMA:

RCThoughts GPS Unit

I recently built one of the RC-Thoughts GPS modules for Jeti, using a GYGPSV3-M8N GPS with a NEO-M8N-001GPS module to a 5V Arduino board. This is the new EX-Bus sensor version of the GPS module.

It powers up and acquires the GPS signal and displays position accurately, however the altitude read-out is incorrect.

It looks like there is a units conversion issue. My location definitely corresponds to the altitude shown, but what is shown has the units reversed.

When set to Metric units, the Altitude reported has the units shown as ft. The value shown agrees with my actual location in ft (663ft).

When set to English units, the Altitude is still reported in ft, but the value is converted to meters (199m), but it is shown as 199ft.


I live right next to Spinks Airport, just south of Fort Worth, TX, with an official reported elevation of 700.4ft.



I sent the data to Tero-S who replied that he didn't think that there was an issue but he would check - that was in January, and I've not had any replies to follow-up questions.

Has anyone else seen any issues with reported altitude with the RC-Thoughts GPS module?

Thanks

Have you change te units with the Jetibox(emulator) in the GPS sensor?

Yes I have. And tried a full reset also.

Hello
I just tried to switch to feet, indeed I think there is a problem !!
the screen goes well in feet but the values are always in meters !!
Living in France, I never noticed this bug !!

You can test this jetiforum.de/index.php/do-it-yourself/86...gps-sensor?start=174 software. It use the same hardware and connections as the RCT version. V2.3.3 is the last version.

For activating US units you have to change something in te software.

Load the program with Arduiho IDE. Go to the tab settings.h en remove the two "//"in the line "//#define UNIT-US"

Hello everyone,

was this also taken into account?
