Background

Prior to liftoff (L O), FDO selects telemetry as the selected source for trajectory processing until the tracking filter is deemed good by NAV at approximately 25 sec MET. This also prevents spurious data points on plot displays as the radars lock up on the vehicle post-L O. Also prior to L O, TRAJ (and ARD Support) ensure that the ARD thrust limiting flags are off and the ARD mass track recycle time is correct to account for the pre-launch SSME throttle up from zero to 100 . Having these...

Ascent Data Flow High Speed Tracking and Telemetry Data CBand

During launch and landing the MCC requires both High Sample Rate (10 samples sec) and Low Sample Rate (1 sample sec) Data from the supporting C-Band radars. The tracking data for launch landing is referred to as Launch Landing Trajectory Data (LLTD) which is High Sample Rate (HSR) data. During an east coast launch, the Eastern Range (ER) Range Operations Control Center (ROCC), selects the best and second best source of launch tracking data by mathematically projecting error ellipses for each...

Oms

Current flight design philosophy does not require an OMS-1 burn, since DI targeting is used exclusively. Though the targeting scheme is currently unused, SI missions nominally require an OMS-1, designed to result in the desired apogee altitude with a minimum fuel expenditure. A number of corresponding OMS-2 target sets are designed specifically for execution after the nominal OMS-1. These targets will either raise perigee (Hp) to the nominal, safe, or minimum altitude, or will result in an AOA....

Procedure

Following Traj Server Database initialization Take Traj Server checkpoint. Perform Confidence Run (reference FCOH SOP 11.2). Can be viewed online at o Load in NOM, OMS-1, and OMS-2 sim lY's (if required). This may also require resetting the K83 L O time. For RNDZ missions, change the K83 GMT L O first before updating the lY's. o Update D65 reference time to sim launch time o Take Traj Server checkpoint. o Replay telemetry data from run chosen during final, flight-specific ascent sim (ref....

Return to Launch Site RTLS

The RTLS abort provides intact abort capability for both 3-engine and 2-engine operation from liftoff through approximately four minutes MET. The powered flight portion consists of the following four phases. Post-MECO entry techniques are described in section 5.1.4.4, below 1. Fuel Dissipation The vehicle pitches to an attitude designed to control lofting while continuing downrange thrusting to deplete excess fuel. The fuel dissipation attitude is based on the velocity at SSME failure (at SRB...

1) The change initiator fills out a change request (CR) form. The CR form is available on the dm server under S division private dm46 forms fdochcr. See page A-3 for an example of this form. At a minimum, the initiator supplies the submission date, a short descriptive title, a detailed description of the change, rationale for the change, and the initiator's organization name. 2) The initiator transmits the CR form to the pertinent documentation editor. 3) The editor reviews the CR and...

OMS Evaluation and TIG Recommendation

If an OMS-1 is required MECO HA lt 95 NM , then the FDO must recommend the desired target set to used for OMS-1 and the TIG. FDO uses the AME and the Ascent Checklist's OMS-1 2 TGTING card to determine the proper target set to use. TARGETING will also use these same tools to independently determine the desired OMS-1 target set. Once the OMS-1 target set is chosen, the recommendation is passed to FD crew. This is required by MECO 1 minute. In the Traj Server, the AME auto-cycles up to four times...

Digital Display Drivers

For all powered-flight ascent operations, including nominal, ATO, TAL, and RTLS one DDD launch field is use. The list below shows the contents of the FDO Ascent DDD panel. The MSIDs of the parameters are in the test plan for this panel. TRAJ SERVER PHASE indicates if the Traj Server is in Launch, Ops, or Landing Phase. LIFTOFF indicates if LIFTOFF has occurred in the onboard, Traj Server, or both. PC lt 50 SRB SEP indicates when the SRB Pc lt 50, and shortly after when SRB separation occurs....

Follow procedures in section 4.1, Initialization for Ascent. The Traj Server will be brought up cold prior to the first launch attempt. For subsequent launch attempts, the Traj Server may be brought up from a checkpoint from the previous attempt reference section 5.4.1, Post-Scrub Pad Abort Actions . Check the entire database per procedures in section 4.1, Initialization for Ascent. Section 4.3, ARD AME Database Procedures, contains a convenient checklist of those parameters which are likely to...

Space Shuttle Range Safety Flight Termination Criteria

To ensure adequate protection from the hazards of a malfunctioning vehicle, criteria are established which require that the flight be terminated if they are exceeded. These criteria are flight-phase dependent, but are developed under the groundrule that no appreciable piece of an exploding vehicle will be allowed to fall behind a set of impact limit lines ILLs which are drawn around the areas to be protected. This groundrule, along with assumptions made regarding the maximum rate at which the...
