The GPS azimuth adjustment tool is a measuring system that comprises the components: eldbook and sensor unit. Reliable communication between these two components is important for the tool to function correctly. Along with the communication, the app version and the sensor unit rmware version must match. This action is ensured by an automatic update mechanism that ensures the correct rmware is installed on the sensor unit from the eldbook.

4.5 Placing in operation the sensor unit

Note 1:This update mechanism synchronises the measuring system components completely independent of the automatic update function for the app update.

4.5.1 Communication between eldbook and sensor unitAs already explained in section 4.3.5 Connection type, the GPS azimuth adjustment tool supports in principle two variants for the communication between eldbook and sensor unit.

4.5.1.1 WLANThe communication between the measuring system components is via WLAN by default. During this process the sensor unit acts as a WLAN access point with which the eldbook can establish a connection.

The WLAN connection parameters are xed and cannot be changed, except for the channel. It is only necessary to change the channel if there are communication problems on site due to overlapping frequencies (on this topic see section 4.3.6.1 Changing WLAN channel).

The following parameters are of relevance for the establishment of a WLAN connection:

SSID: kathrein_gps_aat_<serial_number> e.g. kathrein_gps_aat_CAG1702215

Password: kathreingps

4.5.1.2 Serial data cableCommunication via a serial data cable is available as an optional connection variant. However, its usage is only recommended if communication via WLAN is not possible. The functionality of the serial connection is restricted compared to the WLAN connection such that it is not possible to update the sensor unit rmware via the serial connection.

4.5.2 Establishing connection to the sensor unitThere are two ways to establish a connection from the eldbook to the sensor unit.

One way is to select the connection type in the settings and the related veri cation of the communication path (see section 4.3.5 Connection type in chapter Settings).

The second way is the automatic establishment of a connection during a measuring process. This action is triggered during job processing at the start of the measurement (see section 5.4 Undertaking measurement) or at the start of an independent measurement (see section 4.6 Independent measurement).

Step 1:On placing in operation the Over ow menu item Free Measurement (see section 4.1 Home screen) is used to start an independent measurement. The Establish a Connection screen opens.

Figure 4.5.1.2: Data cable for connection of eldbook to the sensor unit

The data cable comprises three parts:

Micro USB to USB USB to serial Connection cable for sensor unit

Note 2: It is not possible to update the sensor unit rmware via the serial connection.

4.5.3 Sensor module rmware updateVia the automatic update mechanism it is checked whether the app version and sensor module rmware version match. Should this not be the case, the sensor module is updated automatically.

Figure 4.5.3.1: Uploading sensor module update and updating

It is not possible to stop the sensor module update, as otherwise the correct function of the measuring system cannot be ensured.

Step 3:Should a sensor module update be necessary, the sensor module is updated automatically.On the completion of the update, the sensor module is restarted. It is then necessary to establish a connection again.

The communication and the software version are now synchronised. The sensor for the downtilt measurement is calibrated in the factory and is therefore available immediately.Sensor readiness for the azimuth measurement still needs to be established. On this topic see section 4.5.4 Placing GPS receiver in operation.

4.5.4 Placing GPS receiver in operationA GPS receiver must always be prepared for where it is used. Only if the device knows the region in which it is used, and therefore knows which GPS satellites are to be expected in the eld of view (satellite almanac), is it possible to detect the position correctly and to provide reliable measured values in the measuring time speci ed.

Note: Placing in operation a GPS receiver and the related determination of the local satellite almanac in a new region can take up to 12 minutes. After this initial placing in operation, the sensor module supplies a reliable measured value at the latest after 1 minute.

Step 4:To identify the local satellite almanac the sensor module must be operated in the switched on state in a xed position for a maximum of 12 minutes under an open sky.

4.6 Independent measurementUsing the independent measurement, the alignment of an antenna can be checked without a speci c measuring job.During an independent measurement it is possible to select between the measurement of the downtilt, the measurement of the azimuth and the determination of the actual position. During the determination of the position, the position on a map is displayed along with the co-ordinates (for a more detailed description see section 5.4.4 Downtilt measurement, section 5.4.5 Azimuth measurement and section 5.4.6 Position documentation).

Note: The sensor unit contains an energy-saving function. If the sensor unit does not have an existing connection to the eldbook, the sensor unit will be shut down automatically after 15 min.
