Available in-flight interfaces Sea Launch provides several different types of in-flight interfaces to the spacecraft. Brief descriptions of the in-flight telemetry, command, and separation breakwire interfaces are in table 7-2. Table 7-2. In-Flight Telemetry, Command, and Separation Breakwire Interfaces Interface Serial PCM telemetry Analog telemetry Digital telemetry In-flight commands Separation breakwires Description The launch vehicle onboard data acquisition system can accommodate two serial data streams from the spacecraft, up to 2 Kbps combined. This spacecraft data is interleaved within the launch vehicle telemetry downlink. It is recovered and provided to the spacecraft or customer as a part of the postflight data processing function. Serial data PCM codes of NRZL (data and clock/RS422) are accommodated. Other PCM coding schemes are optional. Four launch vehicle analog telemetry channels are available for spacecraft use. These channels will accommodate data input at ≥ 400 samples per sec. The launch vehicle telemetry system will accept up to eight discrete (bi-level) inputs from the spacecraft. The launch vehicle can provide up to four redundant (primary and backup) pulse-type commands for spacecraft use. The commands can be configured in an application of 28 V or as contact closures. The spacecraft is required to provide continuity loops for separation monitoring by the launch vehicle. As a minimum, one loop must be provided for each separation connector, but two loops per connector are preferred. The launch vehicle will provide continuity loops for use by the spacecraft as defined by the spacecraft separation connectors pin allocations. Provided postflight Provided real time Electrical power Both at the Home Port and on the vessels, Sea Launch provides customer EGSE with power from uninterruptible power supplies. Either 50 or 60 Hz power is available. This launch-critical power is fault tolerant and isolated from other power sources. Electrical grounding Each Sea Launch facility provides electrically conductive surfaces (copper plates or threaded studs) for connecting the spacecraft EGSE to facility ground. Electrical bonding Sea Launch provides an SCA-to-launch vehicle interface bond of ≤ 10 mΩ. In addition, the spacecraft-to-spacecraft adapter interface bond should be ≤ 10 mΩ. 7-10 D688-10009-1 REV B
8. SPACECRAFT INTEGRATION AND LAUNCH OPERATIONS Overview Sea Launch optimizes the convenience of West Coast spacecraft processing with a true equatorial launch site. There are three distinct phases of operations: • Phase I takes place in the payload processing facility (PPF). This phase starts with the delivery of the spacecraft to Sea Launch at Home Port and includes final processing of the spacecraft, standalone tests, ordnance installation, fueling, and encapsulation with the payload fairing. • Phase II takes place on the assembly and command ship (ACS). This includes mating the encapsulated spacecraft to the Zenit-3SL launch vehicle and integrated testing. • Phase III takes place on the launch platform (LP). While still in port, the integrated launch vehicle (ILV) is erected and electrical checkout and RF end-to-end tests are conducted. The LP then transports the ILV to the equator. Rehearsals are conducted while in transit. At the launch site the launch vehicle is rolled out to the launch pad for erection and fueling. The launch is then performed by an automated system. Figure 8-1 depicts the overall spacecraft processing flow. A nominal 60- day processing schedule is shown in figure 8-2. Standard deviations from the 60 day schedule may be accommodated on a case-by-case basis. Communication and power service to the spacecraft during integration and launch preparation is shown in figure 8-3.
