Has anyone else noticed that the data from the module is different in these two modes?
In NMEA the longtidue and lat are about 20miles off. when I switch to Sirf binary the long and lat are correct.
Anyone else experience this?
Cheers

Rod you must compare the dates correctly:
D.dddddd
D M.MMMM
D M S.ss
The reason for the difference is that you are comparing the data wrongly.
Sirf is most properly represented by D.dddddd which is not the case with NMEA.
Sorry Rob
The NMEA is represented as D M s
Latitute
Degree 2 characters
Minutes 2 Characters
and a variable number for decimal fractions of Minutes
Longitude
Degree 3 characters
Minutes 2 Characters
and a variable number for decimal fractions of Minutes
You will find that if you compute this to one number then it will look the same as the binary
(datum was a referece to WGS84 which is what the GPS follow by default)
Thank you, you are absolutly correct. It was because the numbers were so close to each other that I assumed that they should be the same! Silly me.
Thanks again
Rod
