Theres several low power GPS receivers out there (ex. Trimble's Lassen iQ), but aside from the hardwre interfacing to it what else is required? Ive never used or owned anything with GPS, just figured it would be a neat project, but is gps data free, just hook up an antenna and go? Or does it require some kind of existing account for authentication?

There is a data acquisition network of many units. Each unit is synchronized to the GPS. It turns out that the common OEM GPS modules have a nasty problem: the GPS time can suddenly jump by +/- 1 second once in a while. There is no indication if the time is stable or not. I tried several different brands and makes; all of them did that. The event looks random; I can't see any correlati...

Hi All, I'm just working on the open source GPS logger with voice recording (to facilitate recording tracks for the http://www.openstreetmap.org project). The current architecture includes: GPS module - http://www.f-tech.com.tw/datasheet/GPS/FGPMMOPA2.pdf - first tests show, that it performs very well even at low level of GPS signal. CPU - Atmega32 or PIC18F4550 - not decided yet (the s...

Hi. I'm working on a project where I am connecting a Garmin OEM GPS Receiver (asynchronous, RX-TX-GND) through the USB port in Windows XP.

The GPS sentence length is 55 bytes plus a LF and CR at the end, one sentence per second. (only the $...

I'm looking for an easy to use/integrate gps receiver. I've come across tyco's products. Is one of these babies all I would need or is there some 'antenna' or other stuff required that's not shown in the picture? I plan to hook it up to an MCU. http://www.tycoelectronics.com/gps/modules.asp If there's anything better you've come across, please let it be known. Thank you.

I need to log GPS coordinates (time and position) every x seconds. I have a GPS receiver connected through RS232. Together I have to log measures from sensors connected to another RS232 port (proprietary protocol). I think the GPS real-time tracking is almost standard so I think there are many hw/sw already available. Is there a software sufficiently flexible to join my custom sensors...

I am looking at a project which requires a simple GPS receiver (not waas/egnos) and a low grade solid state gyro (not a "level") like the ones you get in smartphones.

I often need to do range tests on short-range radio devices from 500 to at most about 25,000 feet separation. A clear line of sight for laser rangefinding is not always possible. Measuring the range using a GPS is simple enough; just set a waypoint at the fixed end, tell the GPS "navigate to that waypoint" then walk away with the other end of the link. However, is there an off-the-shelf GP...

A while back we had a short seminar on DO-178 and I asked the 'experts' how DO-178 dealt with the software in modules from a third party (I used GPS as an example). They said that as long as our software treated the GPS module as a black box or a slave, that we didn't have to ensure that the GPS module's software was DO-178. Is this true or still true? What about modules in general? I h...
