摘要

There are two distinct advantages of the global nature of satellites which cannot be easily met with terrestrial systems: wide-bandwidth-point-to-point and mobile applications. With the availability of telephone, cable, and the internet to link HAMS at fixed sites to each other routinely, we are wasting a lot of potential of our very valuable AMSAT resources by ignoring mobile applications.HAM radio is on the move. Many hams only have time to play radio while mobile, and similarly, whenever a ham contemplates a long trip, his HAM radio is high on the packing list. Although many dream of taking along an HF mobile to play with and to report their progress back home, the $1000 to $2000 investment is just too much of a risk. Two meters is fun, and can bring emergency aid, but it just doesn't provide the nationwide coverage that is needed for the mobile HAM traveler far from home, the offshore boater, or first-response teams arriving in a'disaster area. In many cases, just a brief position/status report or message is all that is needed to assure the health and welfare of the traveler or to summon assistance or alert other comms channels.
