RNSS SYSTEMS OR NETWORKS STATUS
The material presented below was submitted to the 14th RES-609 Consultation Meeting - it is compiled for information only
1. QZSS (Quasi Zenith Satellite System)
Quasi Zenith Satellite System (QZSS) is a Japanese RNSS satellite system employing multiple non-geostationary orbit and geostationary orbit satellites. The coverage area of QZSS is Asia-Pacific region. Each satellite transmits the navigation signals in L-band.
The First Quasi-Zenith Satellite 'MICHIBIKI' has been successfully operated in inclined elliptical orbit. The technical verification for the first satellite has been conducted as scheduled.
Government of Japan has decided to accelerate the development of QZSS and to complete the seven satellites constellation in the future.
2. Galileo
The Galileo constellation is operational, providing its initial services globally. The Galileo constellation currently consists of 15 MEO satellites with active transmissions in the 1164-1215 MHz band. Four additional Galileo satellites will be launched before the end of 2017 and a four more in 2018. Further satellites will be launched in 2019 and beyond, bringing the constellation to 30 active satellites by 2020, but launch dates have not yet been determined.
There has been no change to the associated Galileo data, which remains the same as that submitted to the 10th Resolution 609 meeting. An update is anticipated for the next meeting to include two Galileo satellites (not mentioned in the paragraph above) that have anomalous orbits, but which are likely to be integrated into the Galileo system.
3. EGNOS payloads hosted on SES satellites
Luxembourg informed the meeting that following the launches of the SES-5 and Astra 5B spacecraft in July 2012 and March 2014 respectively, the frequency assignments in the 1164-1215 MHz band for both satellite networksLUX-G6-2-E at5°E and LUX-G7-9E-2 at31.5°E are in operation. Luxembourg also indicates that there are no changes to the data associated with these networks, which was submitted to the 7th and 9th Resolution 609 meetings respectively.
4. WAAS payload hosted on SES satellite
Luxembourg informed the meeting about new submitted data for the frequency assignments in the 1164-1215 MHz band for the satellite network LUX-G9-38-A at 129°W. Luxembourg further informed that these assignments will be brought into use with the SES-15 satellite. The launch date for the SES-15 satellite is currently planned for Q2 of 2017.
5. NAVSTAR GPS and LM-RPS
With regards to the United States systems and networks, there have been no changes to the information for the NAVSTAR GPS system or the LM-RPS networks. In June 2009, the United States submitted a new filing called USRSR which increased the number of GPS satellites to 36, and included an increase in power. The United States brought-into-use USRSR filing and submitted its Notification in April, 2016. Both the NAVSTAR GPS-IIRF and USRSR systems should be treated together as the “NAVSTAR GPS” system. The United States has no changes with regard to the two LM-RPS satellite networks.
Finally, the United States is pleased to report that in 2015 and 2016, 4 new GPS satellites which transmit the GPS L5 signal have been launched. With this addition, 12 NAVSTAR GPS non-geostationary orbit satellites, and two LM-RPS geostationary satellites at the 107.3°W and at the 133°W orbit locations, are currently transmitting in the 1164-1215 MHz band.
6. Inmarsat satellites
Inmarsat currently operates three Inmarsat GSO satellites within the Res. 609 bands. These satellites are currently located at 64E, 143.5E and 98W. Inmarsat no longer transmits RNSS signals in the band 1164-1215 MHzfrom the orbital location at 25E, and so these emissions are not included in the Res609aggregate epfdcalculations performed at the 13th CM.
7. GLONASS
The information concerning the GLONASS-M network frequency assignments in the band 1164-1215 MHz for both FDMA and CDMA signals has not been changed. GLONASS constellation contains 27 satellites in orbit and 24 of them in operation. In 2016 one satellite was launched on 7 February 2016 and one satellite was launched on 29 May 2016. Further launches will be determined by operational necessity.
8. COMPASS
COMPASS system has followed the development of starting with regional services first and expanding to global services later. It has the plan to provide the global PNT services around 2020. The space segment of COMPASS global system will consist of 35 satellites which are 5 GSO satellites, 3 IGSO satellites and 27 MEO satellites.
By the end of 2012, COMPASS system began to provide its services in Asia-Pacific region with fourteen satellites (5GSO satellites, 5 IGSO satellites and 4MEO satellites). The follow-up satellites will further upgrade the regional service performance and expand to the global coverage. At present twenty-one satellites are transmitting signals in 1164-1215MHz.
9. Indian Satellite Navigation Systems - GAGAN and IRNSS
Note: No new status update was received for the 13th CM.
India’s Satellite Based Augmentation System (SBAS) to GPS, GAGAN payload, are operational at 55⁰E and 83⁰E since May 2011 and September 2012 respectively. The third GAGAN payload is planned to be operated from 93.5⁰E. This third GAGAN payload will be an on-orbit spare.
Two of the India’s Regional Navigation Satellite System (IRNSS) satellites of the 11 satellite constellation IRNSS-1A and IRNSS-1B have been launched in July 2013 and April 2014 respectively. IRNSS-1A and IRNSS-1B are geosynchronous satellites with equatorial crossing at 55⁰E and inclination 29⁰. The third satellite of IRNSS constellation IRNSS-1C is a geo-stationary satellite to be operated from 83⁰E and scheduled to be launched in October 2014.
10. Alcomsat-24.8W satellite network
Note: No new status update was received for the 13th CM.
Alcomsat-24.8W is an Algerian GSO satellite network located at 24.8W. It is occupying one active navigation channel in the band 1164-1215 MHz. Alcomsat-24.8W is planned to be launched by the end of January 2016.
11. Papua New GuineaRAGGIANA-18 GSO Network
Note: No new status update was received for the 13th CM.
On August 15, 2013 Eutelsat Americas executed the Authorization to proceed with Boeing, for the design, construction and delivery of E117WB.
The Critical Design Review has already taken place and the production and procurement of the flight hardware has been initiated. As per the contract, the satellite will be delivered on the fourth quarter of 2015 and, as of today, the progress of the program is on track to be delivered on time.
The launch will take place in a Falcon 9 launch vehicle from Cape Canaveral, Florida in the fourth quarter of 2015. The satellite is expected to be ready to start operations on the second half of 2016.
