ABSTRACT:
Modern airborne sensors are controlled and operated through software which performs on a single Man Machine Interface, all tasks
such as sensor control, release and monitoring, as well as flight guidance. Owing to the high automation written into the software,
user interaction is minimized during operation. The software of such a modern system hides the complexity from the user. Operation
is intuitive. Novice users are able to operate such a sensor without attending a training course. Nevertheless, knowledge of
background information and technical details enables users to benefit most from a sensor system. Therefore, training and education
of users is still an important task. The paper is about the concept and tools Leica Geosystems implemented for education and training
users of airborne sensors.

sun elevation and atmosphere must be taken into account to

1.2 FCMS - Flight and Sensor Control Software
The FCMS software is the heart of the ADS40 operation. All
aspects of the ADS40 operation are conducted using this
software. The main tasks are sensor control, flight guidance and
user interface. The operator communicates with the software
through the OI40 operator interface. No mouse or keyboard is
necessary. The FCMS features a newly designed graphical user
interface with the following features: clear icons on large
buttons, simple touch screen interface, pre-defined system
configurations, quick navigation within the menu-tree and on-
line help.

During flight execution a system monitor runs in a background
process to supervise all relevant components of the ADS40
system. The system monitor also checks environmental limits as
well as quality limits given for e.g. the required minimum
number of GPS Satellites, the maximum accepted value for
PDOP etc. In case the system monitor detects a condition in the
ADS40 system where the collected data may be useless for
post-processing, a message window pops up on the 0140. In the
message window suggested actions are listed which are
required by the user to solve the problem.

Figure 1. ADS40 sensor system from the user’s point
Figure 1 illustrates the ADS40 sensor system from the user’s
point of view. The typical user’s task during a survey mission is
sensor operation and survey flight execution. As usual for all
airborne sensors, limiting parameters must be taken into
account. The main factor is ground speed of the aircraft (GS)
which must not exceed given limits. Without this parameter,
frame pictures cannot be taken with the desired overlap or in
case of the push-broom type sensor ADS40 the ground pixels
are stretched in the flight direction. To benefit from the User interactions are reduced to a minimum. The ADS40 sensor
advantages of GPS/IMU systems, GPS constellation as well as operates highly automated. To adapt the sensor to specific
the distance from the survey area to the GPS reference applications the user can configure all needed parameters. All
