SBAS system overviewSBAS Sectoral Applications and Benefits

SBAS in the Aviation Sector

SBAS provides the accuracy, integrity, service continuity and availability needed to reply on GNSS navigation for all phases of flight.

Benefits include:
  • Provision of vertical guidance for all runway ends as compared to ILS (Instrument Landing System) that provides guidance to only one end at a time. This improves safety in landing especially in difficult locations and/or in bad weather conditions
  • Straight-in approaches with reduction of minima during landing down to 200 feat
  • Phasing out of some current ground-based navigation aid equipment/or Backup to existing Navaids including VOR, NDB, ILS Cat I, resulting into cost reduction for Air Navigation Service Providers (ANSPs) and airport operators
  • Route optimization, advanced arrival, approach and departure
    procedures (PBN enabler) resulting in cost saving, fuel saving, CO2 emissions reduction.

SBAS in the Agriculture sector

SBAS improves agriculture capacities through machinery guidance, biomass monitoring, livestock tracking, harvest and yield monitoring

Benefits include:
  • Mechanization of agriculture through machinery guidance, biomass monitoring, livestock tracking, harvest, and yield monitoring. Mechanization can increase the capacity to utilize land by a factor of up to 50 times, and 10 times in the case of animal-drawn ploughs and other tools.
  • SBAS can be used for livestock tracking and virtual fencing as well as in the location of tractors and other equipment in the field.
  • SBAS has been shown to further enhance efficiency by reducing wastage from the over-application of fertilizers, herbicides, and seed wastage during mechanized planting.

SBAS in the geomatics sector

SBAS provides the accuracy, integrity, service continuity and availability needed to reply on GNSS navigation for all phases of flight.

Benefits include:
  • With the emergence of new technologies like PPP by satellite, accuracy levels are expected to reach decimeter levels. In addition, because of its regional nature, SBAS can provide coverage of areas where there are CORS infrastructure gaps
  • Additionally, SBAS facilitates the use of a regional unified measurement reference system based on WGS84, eliminating problems associated with the use of multiple coordinate systems

SBAS in the Maritime sector

SBAS support the efficiency, safety and optimization of marine transportation

Benefits include:
  • General navigation (ocean and coastal) and inland waterway navigation, Search and Rescue, container inventory management, and marine engineering are the identified applications that provide the most contribution through the reduction of ship navigation casualties and pollution as well as security optimization
  • Using SBAS for container management improves the efficiency, safety and economic return of port operations

SBAS in the Rail and Road sectors

 SBAS can deliver integrity and accuracy to Safety Critical applications and specific transport/logistics applications such as:

  • Fleet management
  • Dangerous goods tracking,
  • Low-density Line signalling,
  • Passenger information systems
  • Road user charging (Time and distance-based charge) Road Tolling Policy

SBAS in Location-Based Services

GNSS enables a wide range of Location-Based costumer solutions for a multitude of applications. Now, a new wave of innovative applications call for better GNSS performance which can be used in combination with other disruptive technologies (IoT and 5G). 

Benefits include:
  • Navigation: Route planning and turn-by-turn instructions for pedestrian and road users through a smartphone.
  • Mapping & GIS: Smartphone users can become map creators through digital mapping.
  • Geo-marketing and advertising: Personalised offers to potential customers are created with a combination of positioning data and consumer preferences.
  • Enterprise Applications: Mobile workforce management and tracking solutions help companies improve productivity; asset tracking, mobile advertising and card payments as examples.
  • Safety and Emergency: GNSS coupled with network connection methods provide accurate emergency caller location.
  • Sports: Monitoring of user´s performance through various applications.
  • Games: GNSS enables a wide variety of location-based games in smartphones.
  • mHealth: GNSS allows a vast range of applications ranging from patient monitoring to guidance systems for the visually impaired.
  • Personal and Asset Tracking: GNSS facilitates innovative tracking solutions, such as local geofences.
  • Social Networking: Friend locators embedded in social networks.

SBAS in Drone sector applications

 Typical applications in this sector include the following :

  • Agriculture: Agricultural drone applications are varied but can mainly be subdivided into two segments: Remote sensing such as crop, field and soil monitoring (which then serves as an input to variable rate applications) and other precision agriculture applications like light fertilizer spraying
  • Air Transport (Aviation): Drone package delivery and e-commerce initiatives are appearing world-wide in both urban and rural settings for commercial as well as humanitarian purposes. Additionally, other urban air mobility services such as Air Taxi are expected to appear in the medium term.
  • Geo-information: Aimed at infrastructure monitoring of various kinds (construction, energy, railways, marine surveying, mining, ANSP asset management and NAVAID maintenance…)
  • Surveillance / Public Security: Applications range from border security and maritime surveillance to first response team assistance for police and fire units (civilian identification, assessing safety hazards, evidence gathering)
  • Leisure: For use in many applications such as self-tracking/filming, toys, aero-modelling, photography or drone racing
  • Through SBAS added value of increased position accuracy and integrity, drones can be used across the sectors mentioned to achieve operational needs efficiently and effectively.
