GNSS frequencies, signals, receiver capabilities and applications

Nowadays (August 2017) position data can be obtained generally from satellite navigation systems (SNS), such as GPS and GLONASS, and satellite based augmentation systems (SBAS) which can be either global, such as EGNOS, GAGAN, MSAS and WAAS, or regional, such as NAVIC (IRNSS) in India. Two new global SNSs, Galileo and BeiDou, three new global SBASs, SDCM, KASS and SNAS, and one new regional SBA, QZSS in Japan, are under construction. The generic name given to all these abovementioned systems is GNSS (Global Navigation Satellite Systems). This paper presents details of the following: changes that have occurred in the cumulative core revenue in different GNSS market segments (road, Location Based Service LBS, surveying, agriculture, timing & synchronization, aviation, maritime, drones and rail in 2017) in the last 8 years; an overview of the GNSS industry and location-based services in the world; details of current and future GNSS market evolution; GNSS unit shipments in 13 different categories of maritime application; the frequency and constellation capabilities of GNSS receivers; GNSS frequencies that will be common in the future; the adoption of multi-constellation, multi-frequency and dual-frequency as key enablers of improved accuracy and integrity; GNSS services available for civil and authorized users, and multiple signals in the case of all four global SNSs.
