Type of Restriction Restriction Status

Mass allotment: <= 10 lbs

Volume allotment: <= ½ can

The payload’s center of gravity (CG): In 1”X1”X1” envelope of centroid?

Activation met under requirement: (either 1.SYS.1 or 1.SYS.2)

Yes?

Structure mounts: Top and bottom bulkheads. No

mounts to sides of cans.

Sharing: Fully developed?

• Where are you at on integration?Our plan for integration with Wyoming is fully complete, and we expect things to go smoothly at Wallops. We have integrated with Wyoming before, so this is nothing new to either team.

• Plan:– Wyoming has created correctly sized standoffs to create a rigid

space within which we need to fit; we have been planning our payload to these specifications since the beginning of this project.

– What areas worry you?Our main concern is height. There is always a possibility that things will not go

smoothly during integration, or that there was perhaps a miscommunication during our planning process. We have done everything we can to keep this from happening, and hope still that all goes according to plan. Communication has occurred throughout.

• Testing:

• Testing has gone smoothly, and data from most of those tests was presented earlier this spring.

• Data from the new AVR board will be presented on the next few slides.

• In place of the temperature sensor that is used on the RockOn! boards, we have place a light sensor. Though I know that the circuitry may not be correct to gather relevant data from the light sensor, a voltage change is still visible with the application of light. This is all we need to detect the spin rate of the rocket as it rotates past the Sun.

AVR board tests

We can see that a lot of the background noise present in the other board’s data has been cleared up; this data is much more clean, and will allow for much easier calibration.

This data compares nicely with the low range x data. The voltage change across the graph is much smaller as it should be. Other accelerometers showed very similar data.

A laser was used to vary the voltage across the light sensor. We can see that as expected, with a laser it is difficult to point it consistently at a single point, causing many spikes in the data. We hope to be able to pick up the spin rate of the rocket, much like our experiment last year, with much less equipment.

• The following plots are from a full system test preformed on a spin table.

IMU Data (Roll, Pitch, Yaw)

IMU Data (Accel, x,y,z)

Spectrometer Data• The following data was collected on a spin

table which had a red computer screen at the desired point.

Since the spectrometer’s output is between 0 and 255, we know that the highest wavelength value (Red) is around 2215-250.

Level or Readiness

• Our payload is essentially complete, with minor goals to complete before we fly to VA.

• We will have no problem being fully ready and prepared for flight before we leave

What is Ready

• Both of our spectroscopy experiments are fully developed.

• All mechanical connections have been made and developed, and integrated into the canister to ensure that they fit. We are ready for integration with Wyoming, and expect that aspect to go smoothly.

What isn’t ready

• One data acquisition board is still being made, however an older board was used earlier this year to ensure its functionality. This data board will be completed and tested by June 12th, and will be integrated into the canister shortly after.

• Our GPS system has not been functioning correctly, however we are still working on it, and in the case of failure, will still fly it as ballast weight.

• Action Items:• Development and testing of data acquisition board and

GPS system.• Payload tests and integration into canister to ensure

payload completion

Level Of Readiness Required Tools Inspections Q/A

• We are ready for Wallops, and have begun packing all necessary tools for the trip.

• We are packing all tools that we could possibly need during integration.

• We will assume nothing will be supplied for us, and will have everything we need to integrate, fix, and tweak the canister as necessary

• We will come prepared!

Level Of Readiness Required Tools Inspections Q/A

• Inspections:• We have been through the inspection process many

times here with a mock up canister, and are prepared to do it successfully at the Refuge Inn. Our team has been through this procedure before, so we know what to expect.
