Data Formats

Abstract

GNSS formats have developed within government, industry, and academia. Their standardization has facilitated the efficient development of the GNSS industry. Current GNSS formats support metadata such as GNSS station, receiver, antenna and equipment calibration information, GNSS observation and broadcast navigation information and also GNSS products such as precise orbits, clock corrections, atmospheric measurements and station coordinates. RINEX, BINEX and IGS standards have been widely accepted and have become de facto standards. RTCM de jure standards on the other hand have developed within a standards organization and were adopted by industry. The development of new GNSS constellations has lead to the need for new formats and also encouraged a higher level of cooperation and integration between the GNSS standards groups. The most widely used GNSS standards are described in this chapter.
