This is a good reason to use APRS on Cubesat for telemetry. Imagine if even half of the cubesats launched transmitted their telemetry as APRS packets and simultaneously operated as APRS digipeaters. We could have a global constellation of APRS repeaters feeding the terrestrial internet backhaul in short order. This is not only great for us but a major advantage for the folks running the on board experiments since: 1. It provides a standardized method of formatting and transporting the science data2. Allows the science data to be automatically forwarded to a collection server allowing greater access to the raw data3. Every APRS igate around the world becomes a 24x7 collection node We in turn get a worldwide messaging tool. Imagine being able to notify the whole world at once that you just came up on SO-50 in that really rare grid :) Oh well, at least I think it's a good idea :) Howie- AB2S
