[time-nuts] question about Thunderbolt geo acuracy

[Rob Kimberley]

How accurate do you need your height? 

Remember that height is the least accurate of GPS parameters due to the fact
that you rarely have a GPS satellite directly overhead.

Subject: [time-nuts] question about Thunderbolt geo acuracy

Hi all,
Hope this isn't too chat roomy, however, I have need of a survey precise
geolocation type gps.  I was wondering if the precise timing abilities
extend to its precision in position output?  I have a thunderbolt and one of
those conical white aerials from china and would like to know if this
combination will give me accurate height data.

Thanks

Tim
