TTC TEAM

• Mission Statement
• The purpose of the Tracking Telemetry and
  Command Team (TTC) is to establish a reliable
  wireless communication using a UHF amateur radio
  band, between the nanosatellite and the ground
  station, and for all communications and ground
  station operations, including the active tracking
  of the satellite on orbit

Discussion

• Established basic transceiver control and
  communication between a simulated satellite and
  ground station.
• Started initial dismantling of the Kenwood THD7-A
  for flight readiness
• Initial integration of TTC and DCH subsystems
• Fabricated preliminary antenna designs
• Initial antenna S11 measurements
• Preliminary testing of ground station Yagi
  antenna.
• Established contact with other working ground
  stations

5
Potential Problems

• Complete functionality of transceiver- good
  designs demand good compromises
• Mounting of antenna on satellite
• Antenna as a whole, evaluate other working
  designs
• Further ground station antenna testing
• Mounting of the ground station antenna

6
Learning Expectations

• Learn how to integrate various subsystems
• Learn how a real working antenna works
• Learn full capabilities of transceiver
• Further knowledge of STK software

7
Deliverables

• Flight ready transceiver
• Flight ready working antenna
• Integrate various groundstation components
• Mount groundstationYagi antenna
• Track a satellite that is already in orbit
