6. Operation of the GPS-Logger 2
6.1. Installation
Due to the low weight and the compact desi.gn, installation is unproblematic. An attachment
with Velcro on boards is sufficient and gives quick access to the memory card.
Attention must be paid to ensure that the GPS antenna is pointing up and there are no
shielding materials such as metal or carbon fibre above it.
It has been shown that when used with 2.4 GHz telemetry systems the GPS-Logger should
not be installed right next to the receiver antennas.
The direction of the three axes of the acceleration sensors is printed on the label.
The Z axis always points down when the antenna points upwards. The assignment
X and Y depends on the direction of installation.
6.2. Memory cards
As memory card practically all commercial micro SD cards with FAT16 or FAT32 file system
can be used. Also SDHC cards and memory capacities over 2 GB are supported. However
not all cards are equally suitable, since some cards exhibit an unfavourable behaviour with
continuous storing of data. If an unsuitable card is used, the recording may run intermittently
or even stop.
We recommend the use only with the card provided or available as an accessory from us.
The card is inserted into the slot on the back and
pushed in until it clicks and is flush. The GPS-Logger 2
does not have an ejector for the memory card so the
card is simply pulled out again with the fingers. If
necessary a smll strip of adhesive tape helps.
6.3. Meaning of the LED
The GPS-Logger 2 has three coloured LEDs.
After switching on a run of the three LED indicates the internal initialization.
In operation there are the following signals:
•
orange LED shines permanently
GPS ready, but still no 3D fix, i.e. GPS positioning not yet possible
• green LED shines permanently
GPS and 3D fix ready, i.e. GPS positioning available
•
orange LED flashes at the set recording rate
GPS recording data, but still no 3D fix
• green LED flashes at the set recording rate
GPS recording data, 3D fix
• red LED flashes
no memory card pushed in.
