BT747 - New code signatures

The code signing key used for BT747 had to be upgraded to SHA-256.

Unfortunately that also revoked the old key and apparently the timestamping was not properly done with the previous signatures.  So the java laucher complains that the certificate is revoked.

All files have been resigned and republished.

You may need to launch:

javaws -viewer

[on windows : "Windows Key + R" to access the execute popup where you can enter this].

Buy Transystem GLog 760 Data Logger for Business

You can now order a G-Log 760 GPS data logger including shipping in Europe and VAT included for 89.99€ in 2016 - this is valid for 1 logger from our stock.  Devices are shipped from France, the delay depends on the destination and varies between 2 days and 7 days.   You want to spend less money, the iBlue 747 A+ offer is no longer available.

The G-Log 760 is an industrial type logger which is waterresistant (IPX3) and supports free-fall drops up to 1.5 meters.  It also has enough memory to record 250000 positions.  For more information, seed the manufacturer's page .
The device is slightly bigger than the previous models, but for profesionnal everyday use it is much better, and even for personal use the fact that it is waterresistant and that it does not fall open when it falls is better.

Wanted: small tracker with display and large memory

I currently use a Holux M241, and the features I like most are

  • AA battery: you can get them anywhere on this world
  • Display showing coordinates or velocity or distance
  • Good cooperation with BT747

However, the memory for 131000 track points (less with newer firmware) is a bit tiny for any holiday of more than a week.

I found the "Locosys GPS Walker" with about 2 GBytes of Memory (and a built-in mp3-player, who needs that?), but that thing has some disadvantages:
