[Paparazzi-devel] UTM values with Skytraq

[Jochen Rieger]

Hi paparazzi community,

I use a Venus Skytraq GPS with Lisa/L.
I receive GPS datas, but the utm_east and utm_noth values seems to be wrong. They change the value with each second. Sometimes also negativ.

1.561 88 GPS 29 398214240 -670356032 0 13800 0 0 0 5619774 32 1

1.965 88 GPS 29 522193600 -845262592 0 13800 0 0 0 5620774 32 1

10.897 88 GPS 29 -15769900 546827264 0 14040 0 0 0 5629774 32 1

11.961 88 GPS 29 522193600 -845262592 0 14069 0 0 0 5630774 32 1

13.289 88 GPS 29 -15769900 546827264 0 14100 0 0 0 5631774 32 1

....

Do anyone know whats the reason?

The right value should be 32U 457999.802xxx  542985.77xxx

Is the Venus Skytraq fully compatible?

Thanks.
