SBAS

Satellite Based Augmentation System solutions by Fokker Services Group.

For maximum (worldwide) flexibility Fokker Services Group offers a stand-alone GNSS solution using SBAS compliant GNSS Receivers that are WAAS/EGNOS/GAGAN/MSAS compatible.

The existing Multimode Receiver (MMR’s) units, if installed, may not comply with the latest local operational requirements. Therefore, Fokker Services offers a smart and cost-effective solution by means of a dual GNSS/SBAS Antenna and receivers that are compliant with (E)TSO-C190, (E)TSO-C145/C146() and RTCA MOPS DO-301 and DO-229() no longer requiring the MMR replacement.

The GNSS installation is complaint with EASA CS-ACNS Issue 2 and FAA AC 20-138D Change 2. If applicable, wiring is installed between the GNSS sensor/antenna and the existing MMR “GNSS” user systems.

The Engineering bulletin includes the installation instructions and various manual supplements.
The modification kit comes with receivers, antennas, wiring, brackets, circuit breakers and more.

SBAS Explained

SBAS uses GNSS measurements taken by accurately located reference stations deployed across an entire continent. All measured GNSS errors are transferred to a central computing center, where differential corrections and integrity messages are calculated. These calculations are then broadcast over the covered area using geostationary satellites that serve as an augmentation, or overlay, to the original GNSS message.
