During this period, operations staff work typically 24 hours a day to activate, monitor and control the various subsystems of the satellite, including the deployment of any satellite appendages (such as antennas, solar arrays, reflectors, and radiators), and undertake critical orbit and attitude control manoeuvres.
Satellite navigation solution for the receiver's position (geopositioning) involves an algorithm.In essence, a GNSS receiver measures the transmitting time of GNSS signals emitted from four or more GNSS satellites (giving the pseudorange) and these measurements are used to obtain its position (i.e., spatial coordinates) and reception time.
Game testing, also called quality assurance (QA) testing within the video game industry, is a software testing process for quality control of video games. [ 1 ] [ 2 ] [ 3 ] The primary function of game testing is the discovery and documentation of software defects .
A major subclass is made of geopositioning systems, used for determining an object's position with respect to Earth, i.e., its geographical position; one of the most well-known and commonly used geopositioning systems is the Global Positioning System (GPS) and similar global navigation satellite systems (GNSS).
The satellite was launched on 1 March 2018 [3] and reached geostationary orbit on 12 March 2018. [8] In May 2018, during the satellite's testing phase after launch, a problem was discovered with its primary instrument, the Advanced Baseline Imager (see Malfunctions, below). [9] [10] GOES-17 became operational as GOES-West on 12 February 2019. [2]
A third satellite was later added to the system. From March to November 2010, the FAA broadcast a WAAS test signal on a leased transponder on the Inmarsat-4 F3 satellite. [14] The test signal was not usable for navigation, but could be received and was reported with the identification numbers PRN 133 (NMEA #46).

The satellite's Advanced Baseline Imager (ABI) instrument captured views of Earth. The ABI views Earth with sixteen different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth's atmosphere, land, and ocean.
