I would expect that future data loggers could be equipped with solar cells to extend the battery life more. Here are the details that are listed in the user manual. What this means is you cannot use the DG out of the box – you need to first have access to a computer with a CD drive. Above is an example where I decided to change the logging mode at the top intersection. The logger would still be in standby mode, with a GSM module powered by the solar cell, so that you could wake it up and configure it via SMS

I hope Globalsat can fix that weakness in future versions. Now you can install the main program.

Globalsat tried to use carriage returns but those are not supported by Google Earth, and come out as squares.

Fully charged those are good for 24 hours before the low battery warning comes on.

Even then they hold another 8 hours before finally giving in. Switching between A,B and Glovalsat will not actually change the logging mode – for the logging to resume with the new parameters you have to power cycle the data logger!

You can rename the modes and change their parameters later.

Switching the device off while connected to USB is not easy either – it is not really clear if you actually managed globalsa switch the device globalwat or not because the LEDs are overridden by the applied power. What this means is you cannot use the DG out of the box – you need to first have access to a computer with a CD drive.


This is one of the weak points of the device – whenever you change settings you need to restart the DG The data logger program comes on the included CD but can also be downloaded from Globalsat’s website.

Also, an ultra low power or maybe even mechanical motion sensor could be fitted to switch the logging off when the device has been stationary for a longer time.

This makes it completely impossible to use the Usbb in a fixed car installation sub. It also had a rough day, and showed quite a few bogus data points in countries far, far away Look at that speed!!!

Speaking of the USB cable – it may look a bit strange at first, and you might wonder if it will be dangling loose after a short while. The mode slider is very easy to operate, also inadvertently.

I also liked the fact that the low battery warning comes relatively early, giving you enough time to react. Or you could disable your ad-blocker for this site.

One theory is that if the logger loses and regains a fix then a new track is started.

Specifications Here are the details that are listed in the user manual. Initially I used a tape to hold the cover in place, but fortunately I was able to visit the Globalsat stand at CeBIT and score a replacement cover there and then. I don’t think I like that approach – I would want to be able to start a new track by power cycling the device like it is done on the Wintec WBT They are not entirely accurate.

Note that there is no option to specify if you want to overwrite old data. Carrying the DG on the belt is possible but due to the size of the device this is not overly convenient. But for now you can end up with multiple tracks per journey, and true to Murphy only one track at a isb can be exported to Google Earth.


To add insult to injury the device switches off when USB power globqlsat applied.

The A,B and C modes can be used to log either by distance or by time. Overview Firstly, this is really mostly just a data logger. It comes provided with mAh rechargeable batteries. Google Earth KML is preferred, however that does not contain the altitude data. First you need to install the driver for the USB-to-serial bridge. I will change the mode to log by distance and specify a smaller distance, otherwise I will never fill up that memory When dg100 unit is sub it will likely also stop logging because it may switch off the batteries may lose contact briefly.

You can either affix glbalsat adapter with the provided double sided tape or – less permanent – with a litte provided screw. However, Globalsat have cunningly incorporated a little magnet into the body of the DG, and this engineering trick keeps the USB cable firmly in place when it is not in use. If you are happy with that feature set then the DG is certainly worth considering.
