13. Position Determination
The GPS receiver can be used to determine the current GPS position. Furthermore, the user is able to be informed when the product leaves a
pre-defined (permitted) area. All functions in connection with position determination are explained below.
Please note the following technical notes:
Depending on receiver position, sight connection to the sky and the weather situation, it may take up to 5 minutes until a GPS
localisation can be performed.
The time until the first position is recognised may be reduced by optimised receiver position.
Within the first 30 minutes after position determination, the GPS position data may have a higher deviation. This is connected with the
GPS signal that requires correction data for high accuracy. They are overlain with the GPS signal and are usually transmitted once
every 30 minutes.
a) General GPS Localisation (Command “GPS”)
The following command requests the current GPS coordinates and returns them in an answering text message without assessment. With this
command, the customer needs to assess the coordinates, e.g. by entering the coordinates in a route planner or a website with maps.
The command for this is:
TEST GPS #1513
