Background
The satellite navigation receiver (namely, GNSS receiver) is user equipment of a satellite navigation system, is a terminal instrument for realizing satellite navigation positioning, and can receive, record, store and process navigation signals transmitted by navigation satellites, acquire navigation messages and necessary observed quantities, and realize navigation positioning of users. When the GNSS receiver works, different signal lines are needed, and after the position and time information is successfully calculated, values of different variables are broadcasted. To ensure that it can be used on different types of devices, the data is output either in an international standard format or in a specific format and protocol provided by the manufacturer, which results in poor compatibility of the system integrated data interface. NMEA is an abbreviation of the international marine electronics association, which customizes the data format of NMEA-0183, a set of standard information that defines GNSS receiver outputs. NMEA has become the most common, most versatile, and most widely used data output format for virtually all GNSS receivers, and it is also used in most software packages that interface with GNSS receivers, most common GNSS receivers, GNSS data processing software, and navigation software adhering to or at least compatible with this protocol.
With the rapid development of global satellite navigation systems, differential GNSS is more and more widely used. In order to meet the requirements of high-precision differential positioning and enhanced services of GNSS systems, the international maritime industry Radio Technology Committee (RTCM) set up an SC-104 special committee in 1983 for demonstrating various methods of providing differential GNSS services and formulating various data format standards.
