CN3 vs MC70/MC75 Level 2 Fight Sheet

This is a great document that provides a competitive update on the stengths and weaknesses of the Intermec CN3 alongside the MC70 & MC75 as of  April 2008.  It has analysis of file system performance, WAN, GPS and data that will help us in our sales efforts.
I'm attaching a 3Mb PDF.

In a bid in Uruguay, Intermec

In a bid in Uruguay, Intermec's partner is sayin the CN3e's GPS supports RTCM standard. (Radio Technical Commision Maritime).
Any idea on how to show what is realy supported by CN3s GPS?
Brochures and manuals havo no specs on GPS.

CN3 GPS supports Wide Area

CN3 GPS supports Wide Area Augmentation System (WAAS) used in North America and a similar system, EGNOS, used in Europe. They turn the feature on by way of its iGPS settings. IGPS is an Intermec value-add piece that allows for further configuration of the GPS radio.


Though WAAS and EGNOS are a form of DGPS (differential GPS), they are by now way RTCM. You may read the following links for more information:

http://findarticles.com/p/articles/mi_m0BPW/is_6_15/ai_n6175510
http://www.kowoma.de/en/gps/waas_egnos.htm

The general idea is that if you don't have WAAS enabled in your coverage area, the feature may actually reduce the fix accuracy (and is turned off by most manufacturers). Somehow I don't think WAAS is supported on Uruguay.

Hi Luis, I found that Sirf

Hi Luis,

I found that Sirf III Star chip supports WAAS accoding to their brochure. MC70/75 does not support differential GPS? If not, does it mean that DGPS supporting needs something beyond GPS chip?

Thank you!

The SiRF chip supports WAAS,

The SiRF chip supports WAAS, but the firmware we have chosen to use in the MC75 does not.  This is really a memory limitation that prevents SiRF from supporting AGPS and WAAS together on the SiRF III receiver.
