Quadrant ADS-B is an autonomous ADS-B Ground Station for the reception of 1090 MHz Extended Squitter signals. Consisting of the highly integrated Quadrant ADS-B sensor and its 1090 MHz/GPS antenna system, the Quadrant ADS-B Ground Station provides a compact and self-contained site installation. Its potential for an outdoor setup combined with its low-power consumption and maintenance-free operation caters for installations even at isolated and remote locations.

Quadrant ADS-B directly connects to an IP network and supports remote and interactive system configuration. Once set up, the Quadrant ADS-B Ground Station can provide surveillance data for up to 20 different client systems compliant to the ASTERIX standard. Furthermore, it supports remote control from multiple Quadrant Control and Monitoring Systems.

The Quadrant ADS-B Sensor features auto adjustment of sensitivity and signal noise level. This supports an easy installation without the need for specialised RF tools or a time consuming, tedious laborious installation procedure. All system parameters can be set up using the Quadrant Control and Monitoring System (QCMS), which, in turn, may be disconnected during operation.

QCMS connects via IP to one or multiple Quadrant ADS-B Ground Stations, thereby supporting an integrated system monitoring. By default, QCMS monitors the operational status of the ADS-B Ground Stations and, if so configured, initiates an automatic switchover in case of unit failure.

With its integrated surveillance client, QCMS is able to present the sensor derived raw air-situation from one or several sensors. In addition to the presentation of live data, QCMS continuously captures all sensor information supporting an immediate replay for event analysis.

Depending on the position data provided by aircrafts broadcasting 1090 MHz Extended Squitter signals, the ground station implements an effective measure to realise Air Traffic Control for En-Route and Approach. This is most attractive in areas where the implementation of conventional PSR/MSSR or Mode S radars is difficult or their deployment is inefficient.

ADS-B is suited for En-Route and Approach Air Traffic Control. At attractive investment and low operation costs, the Quadrant ADS-B Ground Station offers a highly sophisticated solution to a wide range of users.

In combination with conventional PSR/MSSR or Mode S radars, ADS-B Ground Stations provide an efficient way of gap-filling. This applies to regions where radar coverage is limited due to line-of-sight obstruction or in areas where radar coverage has not been established.
