Gps Utility 515 Crack
GPS Hackery GPS Hackery • • • • • • • • I've been interested in GPS for ages (the February 1996 issue of didn't do anything to convince me that GPS was boring), but it's only recently that I fired up my text editors and started to write some stuff. I'm interested in a few applications of GPS: precise time transfer, mapping, autonomous navigation and positioning. The mapping angle is obvious. Toss my laptop in my backpack with a USB GPS on one shoulder and a USB wireless interface on the other, and I have a highly mobile platform for wireless site surveys, quality of service testing and wireless security scans. And when I travel it's good to be able to answer 'where am I, why am I in this hand basket and most importantly, how do I get home?' To that end I've actually paid good money to Microsoft for the last few versions of Streets and Trips. Certainly the 'navigate to foo from current GPS location' feature works.
We provide full-service dirt moving, back filling the dirt once the utility lines are in place, and then stabilizing the soil using Fly Ash or Quick Lime methods. The crews at Seamus Excavating use a fleet of the latest Caterpillar earthmoving equipment outfitted with GPS controls and operated by experienced, long term employees.
Navigation and mapping are low-hanging fruit as well, although I know some people who are race car nuts of varying intensity, and it'd be fun to kit out their cars with sensors and go for a virtual ride-along on a race. Another neat application would be to have a virtual co-driver for rally races. With some sufficiently precise measurements of the course and careful measurements of the car's behaviour during a trial run, the virtual co-driver should be able to talk the driver through upcoming hazards.
A few years ago I took a little road trip and brought my eTrex (before I got rid of it) and my TN-200. I'm fairly impressed with the fidelity of the TripNav; its one-second output of PVT information seems to be right on, and it seems to be more stable than the eTrex for holding a fixed position. Then again, I did have the TripNav stuck to the roof of the car, whereas the eTrex was sitting in the back window. Also, my eTrex stopped outputting NMEA after a while, so I didn't get realtime logs from it most of the way.
I was able to download the track log which I used to compare the units, but that was annoying. So the short version is that I'd recommend using a device like the TripNav which is designed for continuous computer hook-up, rather than the eTrex hanging off a serial cable. () Updates (2005/10/25) We're still waiting on SiRF to tell us whether or not we can distribute the binary blobs, but the good news is that the SiRFstar II and III programming procedures are identical. I've got a new laptop; an IBM/Lenovo T42 with onboard accelerometers, which should make for a really interesting platform for doing some dead reckoning hacking. I got about 28 hours of driving in this weekend - went to spokane for a driving school at - and got some really interesting data logs. (2006/09/07) And again. I've been doing most of my hacking on gpsd.
Among other things I've set up a semi-permanent. Another trip to Spokane was arranged, with about 1100km on the racetrack itself. 
I got my for the accelerometers sorted, and wrote a datalogger to integrate gps output and accelerometer recordings. The calibrated accelerometers can also be run at 100Hz, at the cost of increased battery use and elevated interrupt rates. New code snapshot reflects some of this work. (2006/09/12) The for the has been updated - the latest source is also in the source snapshot. Thanks to for useful suggestions and prodding.
(2006/09/18) Apparently my rotting carcass of a NAV decoder wasn't a rotting carcass at all. It was just hibernating and needed a shower. I now have a decoder that parses SiRF messages 14 and 15 and have made some progress on message 8 - the raw NAV message. More about all that in my. (2006/10/12) Just got a Wintec WBT200 receiver - iTrax3 with the uNav chipset. This should be a good weekend. (2006/11/08) Jeff Francis is running a.
(2006/11/16) I got a pair of FV25 receivers, and found that my Trimble interface board is somewhere in the city. There are vendor photos below, and here's my. () Hardware Currently I have a, a, a, a, a, a and an IBM T42 with onboard accelerometers. I had an eTrex but it was fairly annoying to hack at though - the lack of protocol documentation, the low speed interface, etc - and I decided it was time for a new unit more suited to being and staying connected to a computer. The TN-200 is pretty much ideal for my purposes due to the availability of chip set documentation and the fact that it uses the USB serial controller, supported by 's driver.
