Active GPS Tracking Vs Passive GPS Tracking

March 28th, 2010



In the world of GPS tracking, there are two types of products that you can choose for. These two types do have their own advantages and disadvantages, but they can be more efficient to certain needs and wants. You should understand that there are passive and active GPS trackers, complete with their distinct features and benefits. In order to be able to choose the right type to suit your needs, we are going to discuss some of the advantages and disadvantages in this article.

The first type of GPS tracker is the passive one. This passive device don’t give you the luxury of being able to monitor movements and the locations of subjects you are tracking on a real-time basis. You can still attach the device to the subject you are tracking and then take it back later to get a map of their travels. You will be able to download the travel log data from the passive GPS device and use the given software to interpret the data into readable map locations. You can see routes taken, stops made, and various other data once you downloaded the data from the device. If you plan on tracking the subject again, all you have to do is put — or give — the device back to the subject to let it records travel data. However, passive devices and solutions are far cheaper than active ones. You don’t have to pay monthly service charge to use passive GPS tracking solutions; just purchase the solution from a reliable source and you can use it for as long as you need.

Active devices, on the other hand, enable you to track movements and locations of the subject being monitored in real-time. The best way to go is to choose an active solution with web-based tracking interface and reliable map sources, because then you will be able to track the subject from anywhere as long as you have internet connection. These active trackers have GPRS module built-in to allow it to actively transmit movement data to a server; this is why you can track the subject as long as they are within GSM coverage area. Active solutions are great if you are monitoring children or elders as well, because the tracking device is small and compact — some provider also offer wrist-watch GPS tracking devices so it is very easy to use to track people — and very reliable. It is designed with enhanced sensitivity to allow you to track subjects even when they are indoor. The downside of active solution is that it cost more than passive ones. You will have to pay a certain amount of monthly service charge to be able to use the service to track on your subjects in real-time. Still, the cost you have to pay for these services is quite affordable and with the benefits active GPS tracking solution brings the price is very much worth it.

Magellan GPS Sport Trak Vs the Imperfect Storm

December 1st, 2009



To say a GPS saved my life, and the life of my family would be a lie. I could however say, that my Magellan GPS Sport Trak was a reassuring tool during a real life threatening situation. And that would be the truth. More…It was only the second year our family had been sailing, and we decided to venture a little further from our home port. The perfect starter trip, presented itself, when two other family friends decided to take their two boats on a short weekend sail from Bayfield to Goderich Ontario. It’s a pretty short distance. a couple hours sailing there on a Saturday, a stay overnight in different marina, and a couple hours sail home the next day. It also seemed like a perfect chance to try out the new GPS.

GPS And The Real World

The entire trip would be insight of land, and a GPS was probably not really necessary. But, as with all tech gadgets, there is a bit of a learning curve. So, I figured it would be a good chance to learn a bit more about the GPS in a very practical environment. With the added benefit, of something to amuse the cyber kids during a potentially long and boring (translation: no computer games) adventure. The trip up took a little longer then planned, as the wind was of course very light, and not blowing the direction we were heading. It was a nice sunny day, making a longer trip more pleasant. All three boats arrived just fine. The GPS worked fine, and it was kinda cool seeing it track our trip over the lake. Much more fun that watching it track my speed, as I walk around the block. That’s what I did the first day I had it, since it’s really not much fun to play with a GPS standing still.

GPS Bread Crumbs

After a pleasant dinner and fun time in the Goderich marina, we headed of for sleep, with plans to head home early the next day. The next day brought a little more weather early on, so it seem to be prudent to head off early. The wind picked up quickly, and pretty soon we were sailing in 20 knot winds with 3 to six foot waves. The wind of course blowing the opposite direction from where we were heading. A little rough, but we were managing, and we could easily find our way back home by following the shoreline, or our previous days trip, still stored in the Magellan GPS. About 5 miles directly off shore from our home marina, we made our last tack in and could see our home port in the distance. Thinking smugly that we had avoided any storms I relaxed a little. I noticed the big black wall heading toward us from the south, but was sure we had it beat. About 2 miles from our port, I realized just how wrong I was.

A GPS Makes A Crummy Umbrella

The line squall hit us dead on. Winds went from 20 to 30 knots, and the rain poured. We furled our head sail, and sent the kids below for safety’s sake (which of course sent one racing for the head to deposit her breakfast). Over the radio, helpful advice from our friends boats attempted to assure us we would be fine. The worst thing, was that the shoreline completely disappeared. Nothing but black. Sailboats like water, but they don’t do so well crashing into land. As one boating friend tells me, “In a boat, the land is not your friend”. And here we were heading for land, but just not sure where it was. Not a good thing. Fortunately, our GPS had our home port as a waypoint, and all we could do was follow it’s course. Actually all three boats had their GPS set for the home port, and they were following their GPS heading just as we were. Fortunately, it was a quick storm (only 15 minutes or so), a great beginners introductory storm. As the black dissolved, and the sun shone, our GPS had been true. We were right on target at the mouth of the Bayfield river, and it was pretty simple to just sail in and tie up. Fifteen minutes later, we watched the next squall blow through from the safety of our dock. Who says tech gadgets are just toys? My GPS was a real life saver.
