GPS Gone Wild!

[Hballer21]

I had a weird experience trying to find a camping location. I was using the Lat/Long to locate a site. I am AT THE SITE. The lat/long in my Garmin GPS put me in the next town from where I was. I then used the Lat/Long in my truck, and it was wrong, too. I then pulled out my phone and went to the Satellite Finder app. That was accurate within about 25’.

I sat for about two or three minutes and checked these 3 different readings and they all stayed the same. You’d figure that the Garmin GPS should be accurate if any of them are. Anybody have any insight ?

Are you certain the Lat/Long figures were correct? In the early days of GPS, the government would intentionally introduce errors into the GPS satellite clocks periodically for national security reasons. When WAAS was introduced, no intentional errors were introduced because the airline industry was dependent upon its accuracy.

The Garmin GPS is less than 2 years old. The system in the car, less than 1 year. Both ARE accurately reading my speed. Just not where I am going.

Does it need calibrated? Some want you to drive in a large circle or around city blocks to calibrate. Seen this on certain vehicles, there was even options on what band of satellites to use.

I didn’t read anything about driving around. I thought the Garmin GPS was like the consumer’s standard. Now the German unit in my truck, who knows? But that location was relatively close to the Garmin, both wrong (next town over).
