+GeoGeoKiwi Posted June 9, 2007 Share Posted June 9, 2007 i'm looking to buy a new GPSr and have noticed all the talk about the new SIRF chip in Garmins. Can anyone confirm that this give better sensistivity "worldwide" i.e. its not related to WAAS which I understand is only available in NA? Quote Link to comment
+Mach2003 Posted June 9, 2007 Share Posted June 9, 2007 Sirf chipset units have a higher sensitivity, they see sats, when others do not. Sats orbit the globe, better everywhere. Quote Link to comment

Can anyone confirm that this give better sensistivity "worldwide" i.e. its not related to WAAS which I understand is only available in NA? My previous GPS was a GPS 60Cs, and I now have a GPS 60CSx. There is a world of difference in the reception quality of the CSx. I have used the CSx in Europe and in the USA and it works fine with no difference in reception. I might add that the GPS Sats are not Geostationary (they move constantly around the Earth) so you should expect no degradation in New Zealand. Quote Link to comment
+The Wombles Posted June 10, 2007 Share Posted June 10, 2007 All SiRF chipsets work fine around the world and don't require WAAS to do so. In fact I've switched off WAAS for use in the UK since it's still in test mode here. The SiRF 3 chipset offers much better sensitivity and therefore reception under trees and even inside buildings but does take longer to lock if you're moving when you switch on. I use it in the Garmin 60CSx, excellent kit. Quote Link to comment
+imajeep Posted June 10, 2007 Share Posted June 10, 2007 And, just to round out the thread, there are other hi-res chipsets coming to the market. Garmin has a new 'H' designation in their eTrex line. These units apparently use a hi-res chipset other than SIRF that is supposed to be as good or better. Time will tell. Quote Link to comment

Yep, and some of these new chips have tested as much more sensitive and need less power, so longer battery life. Remember folks, SirfIII is a chipset, not GPS standard. JD Quote Link to comment
