APRS/ PRN DATA Transceiver, 3/10/12Project By

• Problem Definition

• Competitive Analysis

• As technology moves forward we advance in how we
  use different devices while, allowing these
  device to be more connected toward 1 or 2
  systems. This is either the internet or a cell
  tower infrastructure. But what would happen if
  those two communication mediums went down?
• Schedule
• 1/24/12 Propose Project
• 2/10/12 Assemble Display
• 2/24/12 Assemble Transmitter
• 3/5/12 Combine Separate Systems into
  one
• Resources
• Matrix display -- Purchased
• Intermediate components Purchased
• Transceiver Completed Build

• Currently there is little to no competition in
  the APRS market, causing a surge in pricing for
  solutions currently available.
• This gives an opportunity for companies in this
  industry to keep building on this technology, and
  monopolize on it by integrating APRS/ PRN into
  everyday devices, mainly for backup communication.

Potential Applications

• Backup infrastructure in case of any sort of
  disaster.
• Alternative for military/ civilian communication.
• Can easily create a mass networks of repeaters,
  to cover large areas
• Great for security systems, vehicle tracking,
  etc
• This technology is already applied to weather
  reporting systems.
• APRS use for Lo-Jack is simple and effective, and
  of course a lot cheaper, as there would be no
  monthly premium.

Solution Specifications

• My project currently receives data ( currently
  one-way communication is setup) from a
  transmitter communicating with a computer
  terminal, and displays data it received onto a
  Dot-Matrix Display.
• The RF link setup that I had assembled is fairly
  simple and demonstrates the APRS equivalent, that
  would exist. Currently APRS transceivers range
  from 80-220, making it unreasonable to
  integrate it into my current project.

Future Improvement Ideas

• Making the device more compact and integrated.
• Reducing or sizing down unnecessary components.
