Team Progress

In the past few months, the team has been working on evaluating and selecting the components for Mysat-1 preliminary design. Power, link, data and mass budgets has been updated based on each subsystem requirements and parameters.

Successful SRR :)

The team have successfully finished the SRR on 23 June, 2016 which have included the following deliverables:

1.Requirements Development Process

2.Mission goals

• Education
• Camera
• Battery

3.Concept Of Operation

4.Systems Engineering

• System architecture
• States/Modes concept
• Components selection criteria
• Configuration management concept

5.High Level Requirement (updated based on the comments gathered from the MCR)

6.Subsystem Requirements

• General
• Mechanical
• OBC, Software
• EPS
• Comm; Licensing
• Payload and ACS
• Test requirements

8. Risks identification

 

Team Progress

The team had a busy month working on the System Requirements Review (SRR) deliverable documents. They have started working on the individual subsystem’s reports where they have created and analyzed the initial list of the components, data and link budgets.

Also, the preliminary ground station’s and the systems’s block diagrams was developed at this stage to see how all the subsystems will integrate and function with each other.

Moreover, each of the subsystems are working on their system requirements which is driven out of the high level requirements.

 

Team Progress

Dear Reader,

In the past months, the team have  learned how to perform orbital lifetime estimation for satellites. Parameters such as orbit altitude, satellite cross area, mass, activities of the Sun… are all part of the calculation and STK helps us to solve it quickly.

Mission Milestones

The team is working very hard to meet the following mission’s milestones at the proposed deadlines.

1. Kick-off – 12/2015

2. Mission Concept Review (MCR) – 4/2016

3. System Requirements Review (SRR) – 6/2016

4. Preliminary Design Review (PDR) – 9/2016

5. Critical Design Review (CDR) – 6/2017

6. Flight Model Readiness Review (FMRR) – 12/2017

7. Pre-Shipment Review (PSR) – 6/2018

8. Launch – 12/2018

Mission Progress

Continuing our path to Space! we had a lot of tasks and responsibilities during the last months.

we had our Mission Conceptual Review (MCR) meeting which was held on April 20, 2016 where we have covered and prepared the following:

1. Mission Objectives and High-Level Requirements Document
2. Human Resources Management (Student Team Organisation)
3. Preliminary Program Schedule (Tasks oriented with owners and deadlines)

 

STK Sessions

Dear Reader,

I appreciate taking the time to read team progress. So…..THANK YOU.

In  3rd & 4th of April, Mr.Diogo from AGI give us a workshop in STK orbital analysis.

And this is what we learned:

1. Orbital lifetime estimation (result chart shows decreasing altitude vs time):
   1. Estimate orbital lifetime of a 1U CubeSat
   2. Estimate orbital lifetime of a 1U CubeSat at a circular 500km orbit
   3. Estimate orbital lifetime of a 1U CubeSat at a circular 600km orbit
   4. For a 3U CubeSat at above orbits
2. Power generation estimation (assume that the CubeSat is covered with Triple Junction Solar Cells 8x4cm each, 24% efficiency):
   1. Estimate average power generated from a 1U CubeSat in 1 orbit
   2. Estimate average power generated from a 1U CubeSat in 1 circular 500km orbit
   3. Estimate average power generated from a 1U CubeSat in 1 circular 600km orbit
   4. For a 2U CubeSat at above orbits
   5. For a 3U CubeSat at above orbits
3. Debris impact risk assessment
   1. Estimate the possibility of debris impact on a 1U CubeSat during a 6 months mission
   2. Estimate the possibility of debris impact on a 1U CubeSat during a 1 year mission
   3. For a 3U CubeSat at above mission durations
4. Link budget calculation (if time allows)
   1. Calculate link budget between the CubeSat and Ground Station at Masdar

MasdarSat-1 team

 

Team Progress

Wednesday 16/3/2016      Mariam Mansouri

Today, the groups who received NAA signals presented the images that they had got.

Then,we discussed the methods  of improving  our results.We came up that a pass with elevation up to 50 deg   give us a  better image.

Next, we distributed the work on FDR document all over the team members 

Finally, Dr.Prashanth  discussed with us the individual assignments that we should submit net time tell the end of spring semester. 

Team Progress

The team discussed the different checks and tests that have to be done such as vibration, shock, thermal vacuum, long duration and etc. in order to achieve mission success. Some other tests include acoustic and radiation tests require sophisticated test facilities and out of scope for our CubeSat project. Moreover, documenting all of the testing procedures for the CubeSat is crucial for qualification and flight acceptance tests. We had a look on the following documents to get a better understanding of the tests and used these as the basis for developing our CubeSat mission requirement.

1. Latest CubeSat Design Specifications document (revision 12)
2. Russian Dnepr Launch vehicle User’s Guide
