Dear R users, #---------------------------------------------------------------------------------------------------------------------------- #There is table containing 1000 (lat, lon, time) GPS positions, wchich should be recognized and labeled in every row of that #recognized position by label from defined POI vector GPS$Lat =c(9,2.2,2,3,4,5,6,7,2,9,2.1,10,3.3,0 , 6, 8, 9) GPS$Lon =c(0,1 ,1,4,4,5,6,7,2,9,1.1,10,4.2,0 , 6, 1, 9) GPS$time =c(0,1 ,2,3,4,5,6,7,8,9,10 ,11,12 ,13...

Hello everyone and best wishes for 2023 :) I have an old *Garmin Drive Smart 50 GPS* and I want to be able to attach it when it is in preboot mode to a VM hosted by a *Debian 11 host*. From what I understand, the preboot mode allows us to flash a firmware before the GPS actually starts (used among other things when the GPS is soft bricked). When I connect the GPS to the host...

To make the things clearer: Postgres: 1 database shared by all customers with these tables: - user - vehicle - driver Firebird: several databases with different names and identical structure with this table: - gps Each customer has a firebird database. The name of the customer determines the database name: - Customer name: C1 - Database name: C1.fdb - Customer name: C2 - Database name: C2.fdb - Customer name: C3 - Database name: C3.fdb ...

Hello, everyone - I have an old Windows app - a ship navigation program - that needs to see GPS input on a serial port (it was written in the pre-USB days.) My laptop, however, has no serial ports - but this same program, when run on a friend's Windows box, can read the GPS info from the USB-connected GPS via the "USB-Serial Driver". This is one of the frustrating bits of this e...

I would like to capture the lat/lon coordinates from a GPS-enabled cell phone or PDA. Is this possible? Must I subscribe to this information from the cellphone network provider, or can I capture it without charge? What devices will broadcast the coordinates? Is there a device that will broadcast its position inband that can be captured by Asterisk?...

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned

...time source; none of the commonly-used time sources (satellite, terrestrial radio, or network) carry time zone information (although WWVB does carry a bit to indicate if US DST rules are in effect). They each use a single global time scale (although unfortunately, not the _same_ time scale). > GPS time is a much better solution, but it?s power-hungry, as you probably know from running GPS on your smartphone. This rules it out for laptops. Not exactly; laptop batteries' capacity is an order of magnitude larger than phone batteries. > The GPS transmitters probably have a higher recei...

So, I already have MS Autoroute 2001 (european version). Against my expectations, this program runs fine with Wine release 20011004. However, the GPS Add-In doesn't work. I'm not completely certain, if it's the serial port (/dev/ttyS0, correctly configured according to all the docs I found) or the gps-dlls with cause the problem. Obviously, there are two different such add-ons. One intended for win95 and the other one for winnt40....

Dear all, I would like to ask you if R has a library that can work with different GPS formats For example  I have a string of this format N50° 47.513 E006° 03.985 and I would like to convert to GPS decimal format. that means for example converting the part N50° 47.513 to 50 + 47/60 + 513/3600. Is it possible to do that with R? What is the name of such a library? I would like to...

Dear R-helpers, I get GPS readings with bug counts (bugs meaning insects in this case) made along rows in crop fields and use these to make maps of bug distribution. The GPS readings are not quite accurate enough for my purpose, so since I know what row each reading is made in, I adjust the latitudinal coordinate using:...

Hi, I am trying to install and make functiona PC Navigator 8 for my father on Ubuntu 9.10 using wine. Software is runnable, i connect BT GPS receiver to ubuntu on rfcomm4, but I am unable to make receiver visible for PC Navigator. Can anyone help he? Thank you

Anyone ever used the iGPS-500 under CentOS 5? Any recommendations on a USB-based GPS that "just works"? Ray

I've installed through wine the program for a gps data logger QSTARZ. The program works fine with wine, but cannot dowmnload the data from the gps because I only have a windows driver for it. Any way to get the windows driver installed in linux so that I could download the data? Thanks Agus -- Dr. Agustin Lobo Institut de Ciencies de la Terra...

I am new to Linux, Ubuntu, WIne etc but despite all that I am operating in Ubuntu 8.10, with MapSource 6.13.6 installed via Wine 1.0.1. I know there is an issue in getting MapSource to recognize the GPS while connected via USB but I am unable to understand the steps provided to solve this issue. I've been advised to enter "sudo modprobe garmin_gps" in terminal and to check the results. So I connect the GPS and get a "/dev/ttyUSB0" file. I've been advised it should b...

Can anyone please hazard a guess at an estimate for a poor old squirrel hunter with a Very Very Dumb Question? Is wine likely to be able to install and run any of the proprietary GPS-interfacing topo map programs (DeLorme, Garmin, Mapquest, et al.) at any roughly predictable future date? The season opens in three weeks, my GPS (Garmin's etrex vista) is full -- and it still contains road maps instead of topo maps, because I can't upload the good ones from linux (FC1). I&...

Currently, my time server is a Sun v240 with a 32-pci gps card (with a proprietary Solaris driver) attached to our gps receiver via an sma cable up to the roof of my building. As I'm migrating almost all of our Solaris servers and services over to CentOS, I'd like to know what other people are using for time server hardware. Any suggestions? --...
