Evolved from the popular, proven 601 and 601HP (high-power) spacecraft, the body-stabilized Boeing 702 is the world leader in capacity, performance and cost-efficiency. The efficiency of the XPC is greater than 91%. These satellites were the first to be launched with the intent to fully position the satellites using electric propulsion, thus requiring 4–6 months following launch to ready the satellite for its communication mission, but at substantial reduction in launch mass and, therefore, launch cost. The contract includes options to support additional Boeing 702 satellites. The device is built in different versions, which are used in different applications. The SES-9, a 702HP model, launched aboard the Falcon 9 Flight 22 on 4 March 2016. Boeing built Intelsat 21, Intelsat 22, Intelsat 27 and Intelsat 29e (the first EpicNG) satellites based on the platform. [9] Corporations and countries have invested in the 702 family’s capabilities, fitting each satellite with the modular components that they need to turn a profit or keep the warfighter safe and informed on the battlefield. Boeing introduced the 702 spacecraft family in 1995, and today more than two dozen are flying, with over a dozen more currently in production. The Boeing 702 separates the bus and payload thermal environments and substantially enlarged the heat radiators to achieve a cooler, more stable thermal environment for both bus and payload. In November 2014, Boeing released information that two of the 702SP satellites they have built—ABS-3A and Eutelsat 115 West B—had completed manufacture and had been stacked conjoined as they prepared for a launch on a SpaceX Falcon 9 vehicle in early 2015. This was to be Boeing's first conjoined launch of two commsats. [17] The two commsats were launched aboard a SpaceX rocket from Cape Canaveral, Florida, at 3:50AM UTC on 2 March 2015 (10:50PM EST on 1 March 2015). Amber lights adjacent to the switches come on when these relays are open. It is a specialized platform for direct service of mobile users. Developed in 1997 for their launch customer Thuraya, it is a special version of the 702HP platform with a 12.25-meter deployable antenna, onboard digital signal processing and beamforming. The first of this new order will be Intelsat 33e.On July 2014, Boeing announced the order of a ninth Intelsat 702MP order, the EpicNG Intelsat 35e. voltage. Each IDG supplies its own bus system in normal operation and can also supply essential and non-essential loads of the opposite side bus system when one IDG is inoperative. These satellites are Boeing's new mid-power version of the Boeing 702 (702MP) satellite bus. With the 2009 introduction of the 702MP "mid-power version", the legacy Boeing 702 platform, which had been continuously evolved, was designated the Boeing 702HP for "high-power". The 702X series consists of the small GEO and legacy Boeing 702 Small Power and Medium Power platforms “married” to Boeing’s latest digital payload technology. According to Moog-ISP, the 702MP platform uses both its bipropellant thrusters and LEROS liquid apogee engine. New members of the platform have been introduced through the years, which allowed the common systems and approaches to span the whole range of mass and power for geosynchronous orbit satellites. Boeing 737 NG, modified Before the two engines are running (and their generator supplies current), the tie bus allows the ground power, or the APU, or a single engine to feed the whole aircraft. Primary electrical power is provided by two engine integrated drive generators (IDGs) which supply three-phase, 115 volt, 400 cycle alternating current. IE 11 is not supported. EL SEGUNDO, Calif., Feb. 8, 2010 – Boeing [NYSE: BA] in late December successfully integrated the satellite bus and payload module for the fourth of six Wideband Global SATCOM (WGS) satellites the company is building for the U.S. Air Force.

Boeing 702 is a communication satellite bus family designed and manufactured by the Boeing Satellite Development Center, and flown from the late-1990s into the 2020s. [19], In June 2015, Asia Broadcast Satellite (ABS) ordered an additional 702SP, ABS-8, planned to be launched by late 2017, in part because they were well satisfied with performance of ABS-3A, even before it reached its operative orbit. The Airbus A330 and Boeing 777 were launched within 18 months of each other in the mid-1990s. These satellites were the first to be launched with the intent to fully position the satellites using electric propulsion, thus requiring 4–6 months following launch to ready the satellite for its communication mission, but at substantial reduction in launch mass and, therefore, launch cost. Boeing's 702 satellite bus platform is what Viasat's newest satellites are built upon. According to Moog-ISP, the 702MP platform uses both its bipropellant thrusters and LEROS liquid apogee engine. [2][15], As of March 2014[update], Boeing had sold four of the 702SP satellites to Asia Broadcast Satellite (ABS) of Hong Kong and Mexico's SatMex, with the first two commsats planned for a paired launch in early 2015.[16]. It covers satellites massing from 1500kg (3,300lb) to 6100kg (13,400lb) with power outputs from 3 to 18 kW and can carry up to approximately 100 high-power transponders. [18], In March 2014, Boeing disclosed an early-2013 order by an unnamed U.S. government agency for three 702SP spacecraft. In February 2014, SES announced that it had ordered a Boeing 702SP-based sat for SES-15. This increases unit reliability over service life. Beginning in 2012, Boeing began manifesting all-electric propulsion commsats on the 702SP XIPS propulsion bus for eventual location in geosynchronous orbit. The 702SP is an evolution of the Boeing 702 satellite, and continues Boeing's five decades of designing and delivering satellite systems that fulfill customer requirements. [11] The satellite is expected to enter service in 2018 in the 105° east orbital slot to replace AsiaStar. In 2009 Boeing introduced the 702MP platform, a mid-power solution based on the high-power 702HP platform. Cookie policy. This is the first commercial satellite to use EP exclusively for attitude control, all station ABS later cancelled the order after failing to successfully finance the project, in part related to changes to the mechanisms of the Ex-Im Bank during 2015. In March 2014, Boeing disclosed an early-2013 order by an unnamed U.S. government agency for three 702SP spacecraft. The power is provided via an unregulated spacecraft power bus. station-keeping functions on the Boeing 702 satellite. D. M. Internal EMI-Filters reduce the conducted emission (CE) and control the Conducted Susceptibility (CS). At that time the legacy Boeing 702, which has continuously evolved, was designated the Boeing 702HP for "high-power." The check for TR serviceability is current, not voltage, because the TR voltage indicates that of the associated DC busses (for TR's 1 & 2).
