GPS units for truckers by [email protected]
Hi, my brother is a truck driver and I'd like to get a GPS unit for him. He said he's talked to other truckers that swear by them but he didn't get the manufacturer or make. I'm finding very little on the web about trucking specific units. The Magellan unit I looked at explicitly warned that bridge heights are not included in their database. I have an email sent to Garmin asking about this...

Navman accused of price fixing. by John Tserkezis
Primarily of interest to Australians only, I thought this would be very dodgy considering the better reputation Navman (with the novices at least) has here among the GPS crowd. I really didn't think that the satnav industry was this cut-throat. http://business.smh.com.au/navigation-maker-fined-125m-after-steering-wrong-course/20071226-1j1x.html SATELLITE navigation maker Navman has...

Plot your GPS data with GPS time of week and UTC time on the x-axis by Glenn MacGougan
I've put together an open source app, plot2d (http:// plot2d.sourceforge.net), for plotting data (from ASCII files, almost any delimiter) directly to a compressed image. It uses a simple ASCII options file. It can also generate statistics for each series. The program lets you plot GPS time of week and UTC time on the x-axis. The project is still in the Alpha development stage. I'm looking...

GPS Simulator Validation by Sastry
Hi All, The are tests, Core Test Plans etc. clearly defined for receivers. Are they any agencies or something like that for certifying or validating simulators? For examples, how does claim that one's simulator is fine and acceptable? Sastry

what else spoils GPS signal reception by Otavio Exel
hello All, note: fisrt post in this group; please, be gentle :-) the avenue where I work is lousy for GPS reception: many and very tall buildings on either side, lots of TV and FM antennae's around... but I notice that sometimes I drive the entire 3km without locking a single satellite while some other times I lock 3 or 4 in 5min;

Mac OS X equivalent to SiRFDemo? by isw

GPS antenna compatability by PeterK
I have a Garmin GA27A antenna that I use with a 12XL. I believe it requires a 5v feed from the GPS to operate (used to be technical spec sheets on the Garmin site years ago?). I would like to use the antenna on a GPS enabled PDA (Asus A639) but can find no reference to requirements/specification. Is there any info on the web on external antenna - are they all active antenna? Any grounds to...

Old Vs. New Street Names by Happy Trails
In many large Asian cities, and elsewhere too, I would guess, major street names have been replaced by usually egotistical regimes wishing to assert their idiocy. Thus major thoroughfares are referred to by tourists by their new names, as that is what is mandated for printing on new maps, while locals know the streets, in most cases, only by the old names they have been using forever. This...

Do You Need Millennium Plus GPS Car Tracking? by virig[_2_]

RTK and Attitude by [email protected]
Low cost MEMS gyroscopes perfrome reasonabley well in all aspects but drift. They drift way too much to be used for a vertical gyro reference. You can buy expensive gps based multi antenna attitude systems that have multiple common clock receivers. These do real time RTK calculations to determine attitude. Is it possible to do something at lower cost? My Applicaiton is a earth based hovering...

CLOUD FORMATION ON THE FAULT LINES http://www.meteoquake.org As the tectonic forces push the plates or sections of the plate against each other of past each other, stresses build up in some subvolume of rocks. At constant speed of the pushing, the stresses increase non-linearly, meaning the they will sooner or later "go through the roof" (that's when the EQ occurs). But before that "point of no...
