Improve Safety with SBAS-FMS

Universal Avionics SBAS-FMS Family


Universal Avionics' SBAS-FMS is a critical component to meet upcoming global mandates. Its accuracy is already required for current and planned mandates including Automatic Dependent Surveillance-Broadcast (ADS-B), Future Air Navigation System (FANS) and the Link 2000+ Programme.

The primary objective in establishing SBAS is to increase safety for aviation. By improving the accuracy, integrity, reliability and availability of GPS, SBAS increases the navigation capability for all classes of aircraft in all phases of flight. It's because of the increased integrity of the GPS navigation position that SBAS capable systems are classed as primary navigation equipment.

SBAS-FMS Upgrade Incentive Program


Introducing an exciting incentive for non-Universal Avionics operators to trade-in their legacy FMS or GPS system for a new, SBAS-capable Universal Avionics FMS. Throughout 2015, qualified FMS and GPS systems will be accepted for a trade-in credit allowance toward the dealer net price of the new system.

Qualified Systems

Garmin GNS 430/530
Honeywell GNS-X
Honeywell GNS-XES
Honeywell GNS-XLS
Honeywell KNS 660
Honeywell NZ-2000

A complete system is required to receive credit toward a complete Universal Avionics SBAS-FMS system. Complete system is defined as a Navigation Computer Unit (NCU) plus Flat Panel Control Display Unit (FPCDU), or all-in-one NCU/CDU.

Offer valid for new orders placed January 1, 2015 through December 31, 2015. Orders must be shipped by December 31, 2015.

What is the Satellite-Based Augmentation Systems (SBAS)?


A satellite-based augmentation system (SBAS) is a system that supports wide-area or regional augmentation through the use of additional satellite-broadcast messages. Such systems are commonly composed of multiple ground stations, located at accurately-surveyed points. The ground stations take measurements of one or more of the GNSS satellites, the satellite signals, or other environmental factors which may impact the signal received by the users. Using these measurements, information messages are created and sent to one or more satellites for broadcast to the end users.

Use of Satellite-Based Augmentation Systems (SBAS) has been growing substantially throughout the world, including:

  • North America: Wide Area Augmentation System (WAAS)
  • Europe: European Geostationary Navigation Overlay Service (EGNOS)
  • Japan: Multi-functional Satellite Augmentation System (MSAS)
  • India: GPS-Aided Geo-Augmentation Navigation (GAGAN)

This technology is a critical component of the FAA's Next Generation (NextGen) program and the EUROCONTROL SESAR initiative.

"Upgrading" to SBAS involves replacing an existing Flight Management System (FMS) with a new SBAS-capable FMS. As an in-line replacement, the Universal Avionics SBAS-FMS constitutes minor changes to wiring, antenna, keying and configuration when certified for most LPV capabilities. Still, most of the existing wiring may be used. Non-LPV SBAS-FMS installations have lesser changes.
