Abstract

The present invention relates to a monitoring system for land-based navigational and landing systems. A monitoring system of this type monitors the functions that are carried out by the navigational and landing system, especially the information that is transmitted to the aircraft. According to the present invention, external interfering influences that are independent of the system are detected and are taken into account in the monitoring.

Claims

1. A monitoring system for land-based navigational and landing systems, in which the functions exercised by a navigational or landing system of this type, especially the transmission and reception of information via the antennae of the system, are continually monitored and evaluated,

wherein additional sensors for detecting environmental conditions and events in the area of influence of the navigational and/or landing system are connected to the monitoring system, information from the sensors gathered in this manner being recorded and stored such that this information can be linked to the specific functional sequences of the navigational and landing system that are detected and recorded at the same time.

2. The monitoring system as recited in claim 1,

wherein sensors for recording optical, acoustic, electromagnetic, and/or general physical processes, especially weather-related events, are installed.

3. The monitoring system as recited in claim 1 or 2,

wherein the operating data and the detected data reflecting the environmental conditions and environmental events of a plurality of navigational and landing systems are transmitted to one central recording and evaluating device.

4. The monitoring system as recited in claim 1,

wherein the collected and evaluated data can be displayed on monitors and/or can be used for preestablished, automatic switching processes within the system area.

5. The monitoring system as recited in claim 4,

wherein the collected and evaluated data and/or the switching processes that result therefrom are classified and statistically evaluated and can be utilized individually or in predetermined combinations in a tutorial of a central data processing system.

6. The monitoring system as recited in claim 4 or 5,

wherein the collected and evaluated data can be collected and linked in time-dependent event sequences.

7. The monitoring system as recited in claim 4 or 5,

wherein the collected and evaluated data are classified in accordance with the location of their origin, or detection.

8. The monitoring system as recited in claim 4 or 5,

wherein the collected and evaluated data can be linked to generally available information such as the time of day, season, or topography.
