[edit] Flight Goals

The initial draft from the 26 Jan , 2006 planning meeting yielded the following objectives. After these goals were set, teams went to work researching ways to support these goals. These will be readjusted after the 11 Feb meeting.

  1. Have the payload return
  2. Have a variety of sensors
    • Temperature
    • Camera (Still, Video)
  3. Reach 100,000 feet
  4. Track the balloon the whole way

The design of Thor's payload will match these goals. On our group meeting 9 Feb, 2006, we will use the Thor 3 Agenda Template. We will also use the Thor 3 Design Template to help map goals to designs.


[edit] Teams

There are three teams

  • Communications - handles tracking and transmission of data
  • Sensors - handless processing and sensor acquisition, control of sensors (like camera position)
  • Flight - Launch and recovery (attaching the balloon, parachute, radar thingy) and ground tracking (tracking the balloon, logging sensor data)

These teams may share the modules.


[edit] Budget

Purchases made:

  • Video and Materials purchases: $15 (poly board) + $204.9 (video) + $65.54 (camera) + $130 (antennas) = 415.44
  • $870.98 - $415.44 = $435
  • Radio shack purchases: $17.62 (rg-58, connectors)
  • $870.98 - 17.62 = 417.38
  • More purchaes: $50 (Walmart: Batteries), $12 (Radioshack: BNC connectors, DB-9s)

[edit] Modules

The design is split into several modules, each of which may be used by several teams. For example, the bi-directional module is used both by the communications team, to periodically beacon a GPGGA string for APRS tracking, and also for the sensors team to beacon APRS telemetry strings.

Each module is a logical division - it's only purpose is to give others an idea of the products you picked and why you picked them and the suppliers you used.
