of GPS in Japan's numerous <a href="/wiki/Urban_canyon" title="Urban canyon">urban canyons</a>, where only satellites at very high elevation can be seen. A secondary function is performance enhancement, increasing the accuracy and reliability of GPS derived navigation solutions. The Quasi-Zenith Satellites transmit signals compatible with the GPS L1C/A signal, as well as the modernized GPS L1C, L2C signal and L5 signals. This minimizes changes to existing GPS receivers. Compared to standalone GPS, the combined system GPS plus QZSS delivers improved positioning performance via ranging correction data provided through the transmission of submeter-class performance enhancement signals L1-SAIF and LEX from QZSS. It also improves reliability by means of failure monitoring and system health data notifications. QZSS also provides other support data to users to improve GPS satellite acquisition. According to its original plan, QZSS was to carry two types of space-borne <a href="/wiki/Atomic_clock" title="Atomic clock">atomic clocks</a>; a hydrogen maser and a rubidium (Rb) atomic clock. The development of a passive hydrogen maser for QZSS was abandoned in 2006. The positioning signal will be generated by a Rb clock and an architecture similar to the GPS timekeeping system will be employed. QZSS will also be able to use a <a href="/wiki/Two-Way_Satellite_Time_and_Frequency_Transfer" class="mw-redirect" title="Two-Way Satellite Time and Frequency Transfer">Two-Way Satellite Time and Frequency Transfer</a> (TWSTFT) scheme, which will be employed to gain some fundamental knowledge of satellite atomic standard behavior in space as well as for other research purposes. </p> <div class="mw-heading mw-heading3"><h3 id="Signals_and_services">Signals and services</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Quasi-Zenith_Satellite_System&amp;action=edit&amp;section=5" title="Edit section: Signals and services"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The QZSS provides the following classes of public service:<sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span class="cite-bracket">&#91;</span>23<span class="cite-bracket">&#93;</span></a></sup> </p> <ul><li>The PNT (Positioning, Navigation and Timing) service complements the signals used by the GPS system, essentially acting as extra satellites.

During the first half of the two year in-orbit test phase, preliminary tests will investigate the feasibility of the atomic clock-less technology which might be employed in the second generation QZSS. </p><p>The mentioned QZSS TKS technology is a novel satellite timekeeping system which does not require on-board atomic clocks as used by existing navigation satellite systems such as <a href="/wiki/BeiDou" title="BeiDou">BeiDou</a>, <a href="/wiki/Galileo_(satellite_navigation)" title="Galileo (satellite navigation)">Galileo</a>, <a href="/wiki/Global_Positioning_System" title="Global Positioning System">Global Positioning System</a> (GPS), <a href="/wiki/GLONASS" title="GLONASS">GLONASS</a> or <a href="/wiki/Indian_Regional_Navigation_Satellite_System" title="Indian Regional Navigation Satellite System">NavIC</a> system. This concept is differentiated by the employment of a synchronization framework combined with lightweight steerable on-board clocks which act as transponders re-broadcasting the precise time remotely provided by the time synchronization network located on the ground. This allows the system to operate optimally when satellites are in direct contact with the ground station, making it suitable for a system like the Japanese QZSS. Low satellite mass and low satellite manufacturing and launch cost are significant advantages of this system. An outline of this concept as well as two possible implementations of the time synchronization network for QZSS were studied and published in <i>Remote Synchronization Method for the Quasi-Zenith Satellite System</i><sup id="cite_ref-TAP_dissertation_25-0" class="reference"><a href="#cite_note-TAP_dissertation-25"><span class="cite-bracket">&#91;</span>25<span class="cite-bracket">&#93;</span></a></sup> and <i>Remote Synchronization Method for the Quasi-Zenith Satellite System: study of a novel satellite timekeeping system which does not require on-board atomic clocks</i>.<sup id="cite_ref-TAP_QZSS_26-0" class="reference"><a href="#cite_note-TAP_QZSS-26"><span class="cite-bracket">&#91;</span>26<span class="cite-bracket">&#93;</span></a></sup><sup class="noprint Inline-Template noprint Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:No_original_research#Primary,_secondary_and_tertiary_sources" title="Wikipedia:No original research"><span title="This claim needs references to reliable secondary sources.
