System Overview

Primary Radio

Secondary Radio

Micro-Trak AIO HA with Hanging J-pole - Link

  • Operates on 144.39
  • Transmits APRS packets with GPS coordinates
  • Need to use high altitude version of GPS or you'll get tracking errors introduced (intended to prevent GPS from being put in a missile)

Cutdown System

Need two methods of “cutdown” (bringing the balloon down from altitude) to fulfill regulatory requirements by FAA

  • Bursting balloon counts as one, so you only need to design one method of cutdown (unless you launch an under-inflated or balloon using a non-conventional material)
  • Melting the rope connecting payload to balloon is a common one
  • Parachute release mechanism

Regulatory Stuff
