Competition Description
To control the size of the competition, only three teams per school are allowed to apply to the competition. It is recommended that schools hold internal design competitions to determine the three teams to apply. If more than three teams from one school apply, the first three applications received will be accepted.

The competition is in five phases.
Phase one is the application phase. Teams must submit an application and a $200 competition fee that is non-refundable. The fee is used to offset the cost of rocket motors and other materials. Applications must be submitted by October 30, 2019. Payments will be requested in early November and must be paid by the given due date.
Phase two is the preliminary design. Teams are to develop designs, prototype, test concepts and generate a preliminary design review (PDR) slide package using the provided template. Teams will submit PDR slides only in PDF format at the designated due date. Teams that do not meet the due date or do not submit in the proper PDF format will be dropped from the competition. A schedule will be made available on when to present a subset of the slides.
Teams will have a half hour to discuss a subset of the PDR slides via telecon. After PDR, a total of 40 teams will be invited to the competition. Phase three is the critical design. Teams will finalize their design and start ordering
components, manufacturing parts, test subsystems and start developing the flight unit. Teams will generate a critical design review (CDR) slide package using the provided template. Teams will submit CDR slides only in PDF format at the designated due date. Teams that do not meet the due date or do not submit in the proper PDF format will be dropped from the competition. A schedule will be made available on when to present a subset of the slides.
Teams will have a half hour to discuss a subset of the CDR slides via telecon. Phase four is the launch weekend. Friday, teams will be scheduled to present their completed CanSat for flight readiness review which must be completed in 30 minutes. The CanSat must 5 be ready to launch at this time. It must be completely assembled and operational. Each team will be scored during the flight readiness review. Teams can only present once at the flight
readiness review at their designated time. Teams late for the review will lose points. CanSats must pass the drop test, fit check, and battery verification in order to fly. Multiple attempts at the drop test are allowed.
Saturday is the launch day where teams will perform final preparations and turn in CanSats by 12:00 hours local time. Launch will start at 13:00 hours local time and continue until all launches are completed. There will be no second flights unless the fault is of the launch provider and there are spare rockets and rocket motors. Phase five is the Post Flight Review (PFR). Post Flight Review is a 15 minute presentation of the flight results and 5 minutes for questions. Awards will be presented at the end of the post Flight Reviews.
For teams to receive certificates of accomplishment and be considered for awards, they must complete all phases of the competition.
Late submissions will not be accepted for any phase and the team will be dropped from the competition. Internet issues, file issues, email issues, and any other issues will not be considered. Submit the documents early to be safe.
All scoring and judging results are final. Scoring is set up to be quantitative with little qualitative scoring to minimize any biases. The competition is operated by a dedicated group of volunteers who spend their own time
supporting various phases of the competition. Some volunteers spend their own funds to attend and support the competition while others are graciously supported by their employers. The competition is designed to provide teams a great educational experience and to minimize the time of the volunteers. Strict due dates, file templates, and file name formats are required to minimize the times of the volunteers who have little time to spare. Please follow all due dates and all submission requirements to help the volunteers.
Team Selection (New, must read)
Team selection will be different. Since the competition is sponsored by US organizations, the competition is now required to include at minimum 20 US teams. During the application phase of the competition, up to 20 teams per country can participate. If more than 20 apply per country, a random selection will be made for the 20 teams per country.
For the top 40 selection, 20 teams are required to be from the US. The remaining 20 teams can be from other countries. Teams from each country will be ranked only among their country. Then the top scoring teams from each country will be selected in a round robin method. The top team from each country will be selected in the first round, then the next top 6 team from each country will be selected in the second round and the selection is repeated
until 28 teams are selected. This will create the greatest diversity in teams and allow more countries to participate.
Mission Overview
Design a Cansat that will consist of a container and a science payload. The science payload shall be a delta wing glider that will glide in a circular pattern, once released. The Cansat shall be launched to an altitude ranging 670 meters to 725 meters above the launch site and deployed near apogee (peak altitude). Orientation of deployment is not controlled and is most definitely violent. The CanSat container must protect the science
payload from damage during the launch and deployment. Once the CanSat is deployed from the rocket, the CanSat shall descend using a parachute at a descent rate of 20 m/s. At 450 meters, the container shall release the science payload. The science payload shall glide in a circular pattern with a radius of 250 meters collecting sensor
data for one minute and remain above 100 meters after being released. Afterwards, the glider shall deploy a parachute to cause the glider to stop gliding and drop to the ground at a rate of 10 meters/second.
The science payload shall monitor altitude, air speed and the science payload shall be a particulate matter/dust sensor to detect particulates in the air while gliding.

Preliminary Design Review
The PDR is a “multi-disciplinary technical review to ensure that the system under review can proceed into detailed design, and can meet the stated performance requirements within cost (program budget), schedule (program schedule), risk, and other system constraints”. The CanSat PDR shall demonstrate:
● An understanding of the CanSat mission requirements
● Allocation and derivation of system and subsystem requirements
● Definition of the CanSat concept of operations
● Overview of preliminary design that meets specified requirements
● Results of, or identification of, necessary trades to support preliminary design. While it
is ideal to have completed trades prior to the preliminary design, it is not necessary.
● Results of, or identification of, necessary prototyping or testing efforts necessary to
support or finalize the preliminary design.
● Preliminary budget
● Detailed development schedule
Preliminary design reviews shall be conducted via teleconference coordinated by the team lead(s). The PDR presentations shall be less than 30 minutes in duration including time for questions. Presentation reviewers shall be permitted to ask questions during the presentation (i.e., questions are not held until the end of the presentation).
The PDR shall follow the presentation template posted on the CanSat Competition website.

Critical Design Review
The CDR is “a multi-disciplined technical review to ensure that the system under review can proceed into system fabrication, demonstration, and test; and can meet the stated performance requirements within cost (program budget), schedule (program schedule), risk, and other system constraints”. The CDR shall demonstrate:
● All PDR level requirement TBDs and TBRs shall be resolved
● Refinement of the CanSat CONOP
● Results of detailed design and analysis for each subsystem
● Verification that detailed design meets system and subsystem level requirements
● Identification of subsystem and system level tests necessary for requirements
verification
● Results of requirements verification tests completed to date
● Overview of mission operations
● Preliminary launch day sequence of events
● Revised budget
● Updated development schedule
Critical design reviews shall be conducted via teleconference coordinated by the team lead(s). The CDR presentations shall be less than 30 minutes in duration including time for questions. Presentation reviewers shall be permitted to ask questions during the presentation (i.e., questions are not held until the end of the presentation). The CDR shall follow the presentation template specified in the “CanSat CDR Outline” document available on the CanSat Competition website. Extra material in the form of backup slides is permitted. Each section of the CDR shall be scored in accordance with the values listed in the outline. The CDR shall contribute to the total evaluation of the CanSat design according to the values listed the section Evaluation and Scoring.
