The spacecraft (SC) is designed to operate in a geostationary orbit and will emit a signal twice as powerful as the previous satellites of the series in North America . In addition, he will become the largest and most powerful satellite companion of the Sirius XM Radio fleet [2] [3] .
Design
The spacecraft Sirius FM-6 is based on the platform of the 1300th Space Systems / Loral series with an active life of more than 15 years. The dry mass of the satellite is 2975 kg (the starting mass of a fully charged vehicle is 6080 kg) [1] . To correct the orbit, the satellite is equipped with Russian SPD-100 plasma engines [3] . The power transmitted to the payload module is 20 kW [2] .
It was originally planned that the satellite would be launched into a highly elliptical orbit of 23,975 × 46,983 km and an inclination of 63.4 °. However, it was later decided that the satellite would be geostationary and would operate at 116.15 ° W. [3] [4] .
The payload of the Sirius FM-6 spacecraft consists of one transponder that operates in the cross-band mode, that is, it receives a signal from Sirius XM Radio earth stations in the X-band at frequencies of 7025 - 7075 MHz and emits in the S-band at frequencies satellite radio 2320.0 - 2332.5 MHz. At the same frequencies, service commands are transmitted and telemetry is received [4] .
Launch Transfer
On November 10, 2011, the Proton-M launch vehicle blocks were delivered to the Baikonur Cosmodrome and its assembly began on November 16. [five]
On December 13, 2011, the An-124-100 Ruslan aircraft of the Polet airline delivered the Briz-M booster block to Baikonur, which will be used as part of the Proton-M launch vehicle for launching the Sirius FM-6 satellite into orbit . [6]
December 24, 2011 the spacecraft Sirius FM-6 arrived at the Baikonur Cosmodrome . [7]
The launch was scheduled for January 2012 [8] , but was later postponed to March 5, 2012. After the SES 4 satellite, launched on February 14, 2012 and created on the same space platform SS / L 1300 , had problems with the solar panel deployment system, the launch of the Sirius FM-6 spacecraft was postponed indefinitely for additional checks [9] . To resolve the identified problems, the satellite was sent to the manufacturer. [10] The Proton-M launcher prepared for launch of the Sirius FM-6 and the Breeze-M booster were apparently used to launch another payload.
Satellite Launch Preparation
On July 22, 2013, assembly of the Proton-M launch vehicle began in the assembly and test building at platform 92A of the Baikonur Cosmodrome . [eleven]
August 27, 2013 from GKNPTs im. M.V. Khrunicheva at the Baikonur Cosmodrome , the Briz-M upper stage was delivered, which will be used to launch the satellite into orbit. [12]
On September 6, 2013, the Sirius FM-6 satellite was delivered to the Baikonur Cosmodrome . [13] .
On October 7, 2013, the assembly of the space warhead began in the installation and testing complex 92-A50 of the Baikonur Cosmodrome . The work includes: mechanical and electrical assembly of the spacecraft with the Briz-M booster block and “rolling” of the head fairing onto the spacecraft docked with the booster block. [14] On October 14, 2013, these works were completed. [15]
On October 17, the Proton-M launch vehicle with the Briz-M booster block and the Sirius FM-6 spacecraft was taken to the launch pad. The cosmodrome specialists began work on the schedule of the first launch day. [sixteen]
At the request of the customer, due to the inoperability of the information reception station in South Africa, the launch was postponed initially from October 20 to 21 [17] , and then to October 25. [18]
Satellite Launch
The launch of the Proton-M launch vehicle with the satellite was successfully performed on October 25, 2013 at 22:08 Moscow time (18:08 UTC ) by International Launch Services from platform No. 200 of the Baikonur Cosmodrome [19] . On October 26, at 07.20 Moscow time, in accordance with the flight sequence diagram after separation from the Briz-M upper stage, the Sirius FM-6 spacecraft was put into the target orbit [20] .
