Planned Launch Site Roles

10

• Before Launch/During Flight– 2 Spotters

• The spotters will be tasked with the responsibility of tracking the CanSat.• The spotters will be placed in the field away from the tents and ground station.• They will be equipped with binoculars.• The spotters after finding the CanSat will inform the judges and return to the ground station with the payload

– 2 Ground Station Operators• The GS operators will be tasked with orienting the antennas and tracking the data stream into laptop

Launch Site Roles

11

• Before Launch/During Flight– 2 Spotters

• The spotters tracked the CanSat.• The spotters went to retrieve the payload and discovered the battery fell out upon impact.

– 1 Ground Station Operator• The GS operator monitored the telemetry data transferred to the computer. The data stopped upon launch.• The data was lost, when another connection was tried to be established.

Planned Launch Site Roles

12

• After Launch– 2 Flight Team members (Spotters)

• One engineer will analyze the data coming in through the telemetry and plot the data to see if it is accurate

• The other engineer will analyze the data in the SD Card– The engineer will convert the NMEA sentence to KML and display the

path of the CanSat on GoogleMaps– The engineer will also plot the data to see if it is accurate

– 2 Flight Team members (GS Operators)

• They will pack the equipment and load the van with the supplies the brought to the field

– After completing the listed tasks, the flight team will keep hydrated and assist the competition in locating other CanSats

Launch Site Events

13

• After Launch– 2 Flight Team members (Spotters)

• Recovered the data in the SD Card• Tried to determine what went wrong with telemetry

communications• Helped out the other CanSat team

– All Flight Team members

• They packed the equipment and loaded the car with the supplies brought to the field

Failure Analysis

• Ground Station lost communication with the CanSat shortly after launch

• Battery detached upon landing • GPS satellite lock failure caused distorted

altitude data
