Question: What was the original name of the global navigation system that consists of 11 satellites, one of which was launched in 1978?

full_context: Document 1: List of satellites in geosynchronous orbit: This is a list of satellites in geosynchronous orbit. These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do. A number of weather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN.
Document 2: GPS satellite blocks: A GPS satellite is a satellite used by the NAVSTAR Global Positioning System (GPS). The first satellite in the system, Navstar 1, was launched February 22, 1978. The GPS satellite constellation is operated by the 50th Space Wing of the United States Air Force.
Document 3: GPS Block IIF: GPS Block IIF, or GPS IIF is an interim class of GPS (satellite), which are used to keep the Navstar Global Positioning System operational until the GPS Block IIIA satellites become operational. They are being built by Boeing, and will be operated by the United States Air Force following their launch by United Launch Alliance, using Evolved Expendable Launch Vehicles. They are the final component of the Block II GPS constellation to be launched. On February 5, 2016, the final satellite in the IIF-block was successfully launched, completing the block.
Document 4: Global Positioning System: The Global Positioning System (GPS), originally Navstar GPS, is a space-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
Document 5: USA-213: USA-213, also known as GPS SVN-62, GPS IIF SV-1 and NAVSTAR 65, is the first satellite in the Block IIF series of Global Positioning System navigation satellites. It will be used to relay signals for the United States Air Force Navstar Global Positioning System (GPS). The satellite was launched at 03:00 UTC on 28 May 2010. It will be placed into plane B of the GPS constellation, and will transmit the PRN-25 signal. PRN-25 was previously broadcast by USA-79, which was retired in late 2009 after almost eighteen years of service.
Document 6: OPS 5114: OPS 5114, also known as Navstar 4, GPS I-4 and GPS SVN-4, was an American navigation satellite launched in 1978 as part of the Global Positioning System development programme. It was the fourth of eleven Block I GPS satellites to be launched.
Document 7: Global Navigation Grid Code: The Global Navigation Grid Code (GNGC) is a Chinese-developed point reference system designed for global navigation. It is similar in design to national grid reference systems used throughout the world. GNGC was based upon the work of the GeoSOT team, headquartered in the Institute of Remote Sensing and GIS, Peking University. The concept for this system was proposed in 2015 in Bin Li's dissertation: "Navigation Computing Model of Global Navigation Grid Code". GNGC allows easy calculation of space and spatial indexes and can be extended to the provide navigation mesh coding. Along with the Beidou navigation system, GNGC provides independent intellectual property rights, globally applicable standards and global navigation trellis code.
Document 8: BeiDou Navigation Satellite System: The BeiDou Navigation Satellite System (BDS, ) is a Chinese satellite navigation system. It consists of two separate satellite constellations – a limited test system that has been operating since 2000, and a full-scale global navigation system that is currently under construction.
Document 9: GPS Block IIIA: GPS Block IIIA, or GPS III is the next generation of GPS satellites, which will be used to keep the Navstar Global Positioning System operational. Lockheed Martin is the contractor for the design, development and production of the GPS III Non-Flight Satellite Testbed (GNST) and the first eight GPS III satellites. The United States Air Force plans to purchase up to 32 GPS III satellites. GPS IIIA-1, the first satellite in the series, was projected to launch in 2014, but significant delays have pushed the initial launch to the spring of 2018.
Document 10: IERS Reference Meridian: The IERS Reference Meridian (IRM), also called the International Reference Meridian, is the prime meridian (0° longitude) maintained by the International Earth Rotation and Reference Systems Service (IERS). It passes about 5.3 arcseconds east of George Biddell Airy's 1851 transit circle or 102.478 m at the latitude of the Royal Observatory, Greenwich. It is also the reference meridian of the Global Positioning System (GPS) operated by the United States Department of Defense, and of WGS84 and its two formal versions, the ideal International Terrestrial Reference System (ITRS) and its realization, the International Terrestrial Reference Frame (ITRF).
Document 11: Indian Regional Navigation Satellite System: The Indian Regional Navigation Satellite System (IRNSS) with an operational name of NAVIC ("sailor" or "navigator" in Sanskrit, Hindi and many other Indian languages, which also stands for NAVigation with Indian Constellation) is an autonomous regional satellite navigation system, that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km around it, with plans for further extension. The system at-present consist of a constellation of 7 satellites, with two additional satellites on ground as stand-by.
Document 12: GNSS augmentation: Augmentation of a global navigation satellite system (GNSS) is a method of improving the navigation system's attributes, such as accuracy, reliability, and availability, through the integration of external information into the calculation process. There are many such systems in place and they are generally named or described based on how the GNSS sensor receives the external information. Some systems transmit additional information about sources of error (such as clock drift, ephemeris, or ionospheric delay), others provide direct measurements of how much the signal was off in the past, while a third group provide additional vehicle information to be integrated in the calculation process.
Document 13: History of GLONASS: The satellite navigation system GLONASS was conceived in the late 1960s, and formal requirements were completed in 1970. The government of the Soviet Union made a decision to develop the system in 1976. Design work was carried out by specialists led by Vladimir Cheremisin at NPO PM in Krasnoyarsk-26. The first launch took place in 1982. Until its dissolution in 1991, the Soviet Union launched 43 GLONASS-related satellites. Work on the system was continued by the Russian Federation which brought it its full operational capability in 1995. In the following years, the system fell into disrepair due to the economic crisis in the country and diminished space funding. Starting from 2000, the government under President Vladimir Putin made the restoration of GLONASS a top priority; its funding was doubled and after a lull of several years, launches were restarted again. In 2003, a new satellite design, GLONASS-M, was introduced. By early 2011, GLONASS had 22 operational satellites, two short of the required constellation of 24 to provide global coverage. The latest and significantly improved satellite type, GLONASS-K, is set to be launched in February 2011.
Document 14: GPS navigation device: A GPS navigation device, GPS receiver, or simply GPS is a device that is capable of receiving information from GPS satellites and then to calculate the device's geographical position. Using suitable software, the device may display the position on a map, and it may offer directions. The Global Positioning System (GPS) uses a global navigation satellite system (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense.
Document 15: GLONASS: GLONASS (Russian: ГЛОНАСС , ] ; Глобальная навигационная спутниковая система ; transliteration "Globalnaya navigatsionnaya sputnikovaya sistema "), or "Global Navigation Satellite System", is a space-based satellite navigation system operating in the radionavigation-satellite service. It provides an alternative to GPS and is the second navigational system in operation with global coverage and of comparable precision.
