Updated January 23rd, 2007 While consumer GPS performance and usability reached a peak when SiRFstarIII was launched two years ago, it's always tempting to go a step further. We saw last year with Delorme's GPS PostPro 2.0 that post-processing was a way to improve static GPS accuracy and now the arrival of systems based on the 5hz MTK chipset is an opportunity to look at the impact in dynamic conditions of higher update frequencies. As usual side-by-side testing is the key to gauging the differences, and you can click here for the results in the "Using GPS systems with >1Hz refresh" discussion thread.
Updated May 9th, 2006 - Hard to believe it's been two years already, and I'm not going to pretend I've been testing GPS PostPro 2.0 each and every day, but I've finally found a good place to talk about it...
...in my "GPS Accuracy and SBAS Testing" project where it helped me determine the position of a reference point with sub-metric accuracy. Anyone interested in post-processing should also check out coyotebush's Kinematic Project.
Updated 05/15/2004 - I have received my sample unit (thanks Brook!) and have started testing it and especially the unique post-processing feature. You can head to this discussion in the forums with any questions and comments.
Posted 05/04 - Delorme have released the Earthmate Blue Logger. On offer are: Data logging in-device for 50,000 points, Bluetooth connectivity for use with a PDA/PC, Sub-meter accuracy with GPS Post-Processing......This is the third Bluetooth GPS with a built-in data logger after the Royaltek BlueGPS (33,000 points) and the Deluo Blackbox (6,500 points) already reviewed in the Bluetooth GPS Shoot-Out. What's interesting with the Delorme unit is the price (starts at $149) and Delorme's expertise when it comes to software solutions. It remains to be seen how the GPS will perform though as I couldn't get results from the Bluetooth enabled Earthmate repeatable enough for inclusion in the "Shoot-out".
