Combining Galileo with GPS and GLONASS
While a GPS-based GBAS will offer improved navigation services for aircraft, might these services be even better if the systems were to use satellites from other constellations besides GPS? In this month’s column, the authors show how GBAS protocols might be modified to accommodate multiple constellations, offering results of preliminary tests using GPS, GLONASS, and Galileo simultaneously. read more

More Airports Across Europe Add EGNOS Approaches

March 28, 2014By

Flight operators can now use EGNOS approach procedures at airports in the Czech Republic, Austria, Finland, and Tunisia, all part of a growing list of airports across Europe that have implemented localizer performance with vertical guidance (LPV) procedures. The European Satellite Services Provider (ESSP), a Toulouse-based company which has the contract for EGNOS system operation and service provision, made this... read more

Applied EM Offers Anti-Jam Antenna

March 26, 2014By

Applied EM’s anti-jam GPS antenna, AJGPS045, has achieved a four-channel Controlled Radiation Pattern Antenna (CRPA) in a very small size, weight and power (SWAP) particularly suitable for airborne platforms. Its footprint is the same as a standard GPS Fixed Radiation Pattern Antenna (FRPA), the FRPA-3. This is a key enabler to bringing greatly improved anti-jam performance to smaller platforms and... read more

SBAS Working Group Looks to Galileo for Aircraft Guidance, Defines L5

February 28, 2014By
Planned GAGAN service coverage for the two different service levels (RNP0.1 and APV1). GAGAN has been jointly undertaken by the Airport Authority of India and the Indian Space Research Organization, ISRO, to achieve smooth transition to satellite-based navigation and seamless air traffic management across continents. GAGAN is designed to provide improved accuracy, availability and integrity necessary to enable users to rely on GPS for all phases of flight, from en route through approach for all qualified airports within the GAGAN service volume. More precisely it is aimed to provide Non Precision Approach RNP0.1 service levels to the entire Indian Flight Information Region and Precision Approach APV1 service (equivalent to the current EGNOS Service) within a specified service volume within Indian land mass.

Plans to harness Galileo and other satnav systems for next-generation satellite augmentation systems for aviation and other high-performance uses took a significant step forward at the latest gathering of worldwide operators and experts, reports the European Space Agency. Satellite augmentation systems combine additional ground stations and satellite transponders to sharpen satnav accuracy and reliability across given geographical regions — based... read more
