SoloPalmari GPS Test Drive (Part IV)
Comparison of 6 PDAs and GPS
- We can't get lost
Travelling at night, with all the light coming from the displays of the PDAs, is not an easy task. We drive carefully, particularly when we turn left or right to test the performance of the GPS receivers. On the other hand, we know we can't get lost: in the car we have 10 GPS systems (the 6 ones in test and 4 other devices for ... backup).
Those who don't drive have anyway plenty of things to do: we must take care of data logs, speed, altitude, to get an idea of the behaviour of the different systems.
- Track log number 2: FSC N560, N520, C550 (with BT-338)
In this second test, track logs collected by VisualGPSce are used to compare three Fujitsu Siemens models: N560, N520, C550. The C550 does not include a GPS receiver: it has been coupled with a Bluetooth Globalsat BT-338 antenna, implementing the chipset SiRF Star III (as in the two other systems).
The behaviour of the three models has been uniform, and only in some situations the Bluetooth receiver is better linked to the route. We have to admit, however, that we positioned the Globalsat receiver in the car in a position where it could see a larger portion of the sky.
