Garmin GPSMap 182C and Simrad TP32 share the same language (NMEA 0183), but they do not have enough in common to talk about. The NMEA sentences that the 182C can transmit are GPRMC, GPGGA, GPGSA, GPGSV, GPGLL, GPBOD, GPRTE, GPWPL, PGRME, PGRMZ, and PSLIB. The first two letters of these identifiers are the Talker ID. GP stands for GPS receiver. PG and PS ...

Original answer below. Apparently I'm not the only one incensed by Garmin's behaviour. Garmin has a firmware update for the PN-60 series version 3.7 that was NOT present on their website last time I looked for it. Could be I used the wrong search terms. Anyway the 3.7 update works. If this took a week longer, I would say, "squeaky wheels get greased" ...

Please edit this answer to add other sites you are aware of. Global, all activities Alltrails (formerly also Everytrail, GPSies, and possibly other sites). ...

GPS track logs can be shifted in time using GPSBabel's track filter: Example 4.8. Time-shifting a track with the track filter The following command line will shift all tracks to be one hour later. gpsbabel -t -i gpx -f in.gpx -x track,move=+1h -o gpx -F out.gpx I expect it will work to add 1024 weeks to the timestamps (it may need to be written as ...

The Global Positioning System is a passive system which calculates the position by comparing tiny differences in the time, which is encoded into the signals, received from different satellites. Nothing is transmitted to any satellite A GPS device is not in itself "tracked" by any external device The only way the position can be known externally is if there ...

I used a Garmin InReach Mini for a 19 day trip down the Grand Canyon this past January. I checked in once a day to say "I'm ok" like you had planned to. I recharged mine about 14 days in since the battery was probably around 20%. It probably would have lasted the whole trip, but it was shockingly cutting it close. I didn't use tracking, had low brightness, ...

According to Garmin, with a 30-minute tracking interval and extended tracking mode, the battery should last for 20 days. Turn the screen brightness down and turn it off every single night when you are in camp to further extend the battery life. On the other hand, the inReach mini battery is 1,250 mAh, one 10,000 mAh battery should provide at least 4 charges ...

Mobile mapping is optimised for colour, which isn't available on any of the e-ink devices I can find, despite talk of colour e-paper since about 2013. Having played with black and white prints of OpenStreetMap via InkAtlas (and having reproductions of old B&W Ordnance Survey map) I can say that stripping out the colour information is hard, and really ...

My background: I am a mountain biker since 1986, and I have extensively used a dozen of different GPS devices on my mountain bikes since about 2003. From that perspective: According to each expert I have been talking to, and according to all literature I am aware of, the barometric measurement of the elevation is by far more accurate than the GPS-based ...

A short answer to the question What combination of settings can I use? None. If you unit is not faulty, you are stuck with your problem. The long answer follows. First off, it would be important to note the difference between what the terms accuracy and precision mean in the context of measurements. These paragraphs explain it quite succintly, and the ...

This is late - however, potentially useful for others in the future. Long story short - you can't delete files that have been added to the memory via computer! All the information, including that found on the official Garmin instructions online indicate that this must be done through a computer connection. However (I can't test this as I don't have a ...
