I've found the old link :
http://www.qsl.net/dl3gaz/decoder/convert.pdf

If you are able to use those sheet let me know .

These are the coefficient as reported in the sonde  (the frequencies
are the same before ) :

TY0 : 15729
T0 : -1953
T1 : 2914
T2 : -645
T3 : 473
T4 : 0 

Bye

The old link is disappeared but fortunately I had saved the pdf file so now look at http://prohu.altervista.org/convert.pdf Let me know. greetings enrico

Hi,
is anybody of you be able to decode rs80 signal??
I have tried with the "famous" german sheets intructions but i don not
understand how to use the calibration coefficients.

For example if these are the frequencies:

F1 = 9690 Hz for the first coefficient
F2 = 7665 Hz for the second coefficient
FT = 8876 Hz for the temperature sensor


Which is the temperature? if you try to calculate let me know!!

thank you for help.

This is incorrect, the actual regulation prohibits exporting receivers capable of reporting position at greater than 60,000 feet *AND* 1000 knots. Some GPS manufacturers interpreted the AND as a logical OR in the past. These days, most GPS chipsets will continue reporting position above 60,000 feet if speed is less than 1000 knots, and vice-versa. Marc

That's like saying that fifty quid I owe you is peanuts compared with the size of the world economy, so I'll keep it. Paul Burke

Keep in mind most civilian GPS recievers will not resolve an altitude above 60,000 feet. Depending on what you're doing, this may or may not be a purchase consideration. -- Linux Registered User # 302622 <http://counter.li.org>

Altitude error will always be worse on a GPS system, at least until a method is devised so that the receiver can see the satellites that are below it. ;-) 1 part in 10^13 is pretty darn accurate. IIRC when I was at college the international definition of the second (the most accurately defined standard unit) was accurate to 1 part in 10^12. If you need greater accuracy then you have to perform long term filtering of the position data from a fixed installation, then you can get to the sub 1 metre fix. S-V

Also altitude is quoted on all GPS systems that I have ever seen, to have a much greater margin of error than surface coordinates.
