Background

This training is meant to help you become a safe and effective member of a HABET Recovery Team operating out of the Clyde Williams Field Primary Launch Site. It is also valid for any other launch site.

The Recovery Team’s primary job is the recovery of the spacecraft after landing. It’s secondary concern is reception of data from the spacecraft before launch, during actual flight, and after landing. The Recovery Team must also collect pinhole video and track the spacecraft during the flight.

HABET Recovery

Menu

(HOWE HALL PRIMARY LAUNCH SITE)


HABET Team Menu


The Recovery team must begin operations prior to the MRR to ensure the recovery vehicle is fully prepared for the flight.

Although most recovery procedures do not take long to complete, it is important that they are completed before the various steps in the flight timeline to ensure that all systems may be checked for proper operation.

Note RecommendedStart Time

HABET Recovery

Menu


The Recovery Director will direct you to follow certain procedures at certain times.

However, if you notice that a procedure has been missed, or think that something is wrong in any way, it is your responsibility to point this out to the Recovery Director.

Only trained members of the Recovery Team are permitted to operate any of the Recovery Team equipment while a flight is in progress. However, observers may ride in the recovery vehicle. It is YOUR responsibility to ensure that only authorized personnel operate the equipment.

HABET Team Menu


HABET Recovery

Menu


Recovery Team Procedures begin prior to the MRR with the MRR Checklist.

By following all of the Recovery Checklists, the Recovery Director ensures that all procedures required to prepare the Recovery Team for the flight are completed.

While it is the Recovery Director who will follow the checklists, as a member of the team you should be familiar with all of them so that you can be sure no procedures are missed, and so that you understand when and why procedures need to be completed.

Recovery Team Checklists

The recommended start time indicates, where applicable, the time that this procedure should be started during a normal HABET mission. This time is measured from some fixed marker in the mission, such as FRR, MRR, or Launch.

Certain standard information can be found at the top of every Recovery Team Procedure.

The Master Timeline reference indicates, if applicable, where on the Mission Manager’s timeline this procedure should be carried out.

HABET Team Menu


HABET Recovery

If there are rules associated with when or how the procedure should be carried out, they will be specified here.

HABETHABET Recovery Team Recovery Team Training Training Certain standard information can be found at the top of every Recovery Team Procedure.

Lastly, if the procedure is dangerous, there may be a warning or caution notice underneath the rules. For example, the Vehicle Setup Procedure may cause death if not followed correctly. Electrocution from power wires or Electromagnetic Radiation from the antennas on the rooftop of the recovery vehicle can cause serious personal injury.

MRR ChecklistThe MRR checklist specifies the procedures to be carried out before and during the MRR.

First, a recovery vehicle must be secured from Transportation Services. This must be done through the HABET Manager. To ensure the correct type of vehicle is available, this MUST be done several days in advance.

Also, a Recovery Team member must be authorized to be able to drive an ISU vehicle - this can take several weeks (this person is usually picked from a pool of approved people).

HABET Team Menu


HABET Recovery

Menu


Second, the Recovery Team must check that all of the equipment on the Recovery Equipment Checklist is available for the mission.

Once a piece of equipment is known to be available, it should be checked off in the MRR column of this list.

Recovery Procedure

s Menu

HABET Team Menu


HABET Recovery

Menu


Note: At this time, checking that the equipment is functional is not required since this would require a functional, operating spacecraft, which may not be available before the MRR. However, if a piece of equipment is clearly not functional it should be noted and brought to the attention of the RD and MMGR.

Ensure all batteries are charged before FRR.

When the MMGR asks for the “Go for internal Power”, all Recovery Team members should be in and around the Chase vehicle - this means that Launch and departure are a few moments away.

After the spacecraft has been switched to internal power, the RD must verify that the telemetry still indicates a GPS lock and that the spacecraft still seems to be operating within normal parameters. Once this has been done the time should be noted.

After the Launch Team has finished tying off the balloon and attaching the various tow lines and cables, the LD will ask the MMGR for approval to launch the balloon. The MMGR will then poll each Director to make a last check that all equipment and the spacecraft are operating properly.

For the Recovery Team this means all team members are near the Chase Vehicle and ready to go AND that all equipment is functioning AND the telemetry indicates a GPS lock. Once ALL of this has been verified - the RD will give a “Go for Launch” signal to the MMGR and note the time.

Recovery Procedure

After the “Go for Launch” signal is given by the MMGR the LD is free to release the balloon at their discretion. This means that departure of the Recovery Team is moments away and everyone should be prepared for departure. The only person outside of the vehicle will be the person capturing pinhole video with the Yagi antenna. Once video signal has been lost, the RD will ask the MMGR for permission to depart for the initial LZ.

At this time the pinhole video capturing equipment should be powered down and stowed in the rear compartment of the chase vehicle. The handheld video camera should also be retrieved from the Launch Team so that the landing of the spacecraft can be recorded.

Once the Recovery team has departed, the ‘Recovery Operations’ procedure can be started.

Once the MMGR has called “Roll Call: Go for Launch”, the RD makes his response for ‘Go’ if and only if there is telemetry being received on the laptop AND there is a GPS lock indicated.

Pinhole video capture should be maintained until loss-of-signal (LOS) - this will occur a few minutes after launch.

Once the Recovery Team has left the launch site, it must proceed to the predicted LZ immediately.

Typically this will take about the same amount of time that it will take for the spacecraft to complete it’s flight.

The ‘navigator’ should map out the best plan for proceeding to the landing zone using the county maps available to make sure the team reaches the LZ before the spacecraft lands.

Telemetry on the laptop should be monitored continuously to insure that good packets are being received, and that the spacecraft is maintaining GPS lock. The ‘health’ of the spacecraft can also be monitored with the telemetry.

Contact with the Flight Team should be maintained to help determine if any change in predicted LZ or flight path is occurring during the flight. This should be done at approximately 10 minute intervals. On longer flights (flight distance greater than 75 miles from Ames) mobile radio communications with the flight team may be lost. This makes constant updating of position and predicted LZ critical.

Visual spotting of the balloon is usually possible during the drive to the initial LZ. GPS location can be used to determine distance and elevation from chase vehicle (binoculars can be used to enhance sighting ability).

After the balloon has burst or cutdown has been accomplished, the Flight Team will update the predicted landing zone.

If the LZ has changed, the Recovery Team MUST move quickly to the new predicted LZ.

If visual sighting of spacecraft is possible videotape and still pictures should be taken. Also, if the Recovery Team is in a stationary position, pinhole video should be captured of the landing.

The spacecraft will have landed once its GPS altitude is around 300 meters (1000 feet MSL). If visual sighting of the spacecraft was lost or the Recovery Team was not at the LZ, the Chase vehicle should be moved to the last GPS location indicated on the telemetry.

Once the spacecraft has been spotted on the ground the Recovery Team may move in to retrieve it.

After locating the spacecraft, the Recovery Team may retrieve it. If team members must enter onto any private property (most likely) - PERMISSION FROM THE OWNER MUST BE OBTAINED FIRST!!!!

If it is not evident who the owner is or there are no buildings nearby, the team may proceed with caution. Care must be used to keep crop damage etc. to a minimum.
