Classification

Satellite aeronautics systems that accommodate added accurateness and candor ecology accessible for noncombatant aeronautics are classified as follows:4

GNSS-1citation needed is the aboriginal bearing arrangement and is the aggregate of absolute digital aeronautics systems (GPS and GLONASS), with Digital Based Accession Systems (SBAS) or Ground Based Accession Systems (GBAS). In the United States, the digital based basic is the Wide Area Accession Arrangement (WAAS), in Europe it is the European Geostationary Aeronautics Overlay Account (EGNOS), and in Japan it is the Multi-Functional Digital Accession Arrangement (MSAS). Ground based accession is provided by systems like the Local Area Accession Arrangement (LAAS).citation needed

GNSS-2citation needed is the additional bearing of systems that apart provides a abounding noncombatant digital aeronautics system, exemplified by the European Galileo accession system. These systems will accommodate the accurateness and candor ecology all-important for noncombatant navigation. This arrangement consists of L1 and L2 frequencies for noncombatant use and L5 for arrangement integrity. Development is aswell in advance to accommodate GPS with noncombatant use L2 and L5 frequencies, authoritative it a GNSS-2 system.¹citation needed

Core Digital aeronautics systems, currently GPS (U.S.), GLONASS (Russia), Compass (China), and Galileo (EU).

Global Digital Based Accession Systems (SBAS) such as Omnistar and StarFire.

Regional SBAS including WAAS(U.S.), EGNOS (EU), MSAS (Japan) and GAGAN (India).

Regional Digital Aeronautics Systems such as China's Beidou, India's yet-to-be-operational IRNSS, and Japan's proposed QZSS.

Continental calibration Ground Based Accession Systems (GBAS) for archetype the Australian GRAS and the US Department of Transportation National Differential GPS (DGPS) service.

Regional calibration GBAS such as CORS networks.

Local GBAS embodied by a individual GPS advertence base operating Real Time Kinematic (RTK) corrections.
