Generic Telemetry Module

ASRI Requirements

To assist with the Small Sounding Rocket Program (SSRP) ASRI have requested the following 'loose' specifications to promote an initial discussion among the HackerSpace/Lunar Numbat communities:

Physical Size

• 127 mm diameter x 150 mm long
• Conform with standard bolted interface. Ref ASRI payload user guide.

Physical durability

• Withstand acceleration of 70 G
• Storage Chip protection via resin block or equivalent

Range

• 10 km line of sight, possibly more.

Telemetry

• Sample rate at 10 hz in real time over RF and 100hz stored locally. 100 hz baseline with option for much faster sample rates if necessary. ie. Mach shock wave recording.
• 12 bit (minimum)
  • Channels - If 16 channels is a sweet spot for hardware design then the following would apply.
  • 7 x 100hz "payload"
  • 3 x Accelerometer
  • 3 x Gyro
  • 1 x temperature
  • 1 x barometric pressure
  • 1 x GPS - how will the GPS serial stream incorporated?

Video

• 2 x standard definition cameras at 25? FPS
  • 1 x up
  • 1 x down

Antennas

• Integrated "Wrap-around" type would be preferable for TLM/VID/GPS

Bandwidth

• 100 Mhz to xmit telemetry, video & GPS data.

Battery

• Lithium Polymer

Desirable

• Option for RF uplink connection
