Satellite Simulated Emergency Test. For Voice birds: . . . . [proposed] Net controls take check-ins of position and status from field stations. Using only a Handheld! You can send your Satellite EMail from the Kenwood TH-D7(g) shown above, or the new Yaesu VX-8R (or the TM-D700 and 710 APRS mobile radios) via PCSAT-1, ISS, or GO32. . . Just press the MSG button, select INPUT on the MSG Menu, enter EMAIL as the address, and make the first text of the message be an email address followed by your message. .
In the example below, an EMAIL to A3XYZ@AMSAT.ORG says OK in OceanCity with HT & whip!. . If your email is digipeated via the satellite, then you will see MY MESSAGE flashed on the screen indicating success. . ANY TNC WILL DO: . APRS EMAIL Procedures: . By sending the SSET email directly to yourself, you get the feedback that it was successful. AMSAT OPERATING AREAS: . PORTABLE AND MOBILE OPERATIONS: . Simply stated, we don't always need a PC, for some basic satellite communications.
ECHO FOR EXAMPLE: . ASTARS: an APRS Satellite Tracking and Reporting System. ASTARS SATELLITES: ASTARS stands for APRS Satellite Tracking and Reporting System and refers to digital relay satellites and the global APRS internet linked system of ground stations that tie it all together into full time 24/7 access to these downlinks on the web (See ISS) and (See PCsat). These satellites dating back to 1998 also allow end-user-to-end user real-time digital data exchange typically between mobiles and handhelds. . Email from handhelds is easy using any of the Kenwood or Yaesu APRS walkie-talkies.
See the Satellite Simulated Emergency Test page. Tracking: And you don't need any tracking software to know when to operate these birds on a daily basis. See how. Or you can use prediction software to determine all the passes for a single day. For example, see the pass plan for Field Day 2002 when there were 9 amateur digital relay satellites operational providing passes all day long giving excellent satellite contact alternatives to the overcrowded Voice FM birds.

What is APRS? APRS is a real-time tactical digital communicatons protocol for exchanging information between a large number of stations covering a large (local) area. As a multi-user data network, it is quite different from conventional packet radio. APRS is different from regular packet in four ways. APRS turns packet radio into a real-time tactical communications and display system for emergencies and public service applications (and global communications). Although the recent interfaces to the Internet make APRS a global communications system for live real-time traffic, this is not the primary objective.
APRS Data APRS provides universal connectivity to all stations by avoiding the complexity and limitations of a connected network. Now there is even a nation- wide live APRS tracking network on the Internet! APRS-IS. Automatic Packet Reporting System. APRS beacon transmitter with GPS receiver. Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time tactical digital communications of information of immediate value in the local area.[1] In addition, all such data is ingested into the APRS Internet System (APRS-IS) and distributed globally for ubiquitous and immediate access. Along with messages, alerts, announcements, and bulletins, the most visible aspect of APRS is its map display.
Anyone may place any object or information on his or her map, and it is distributed to all maps of all users in the local RF network or monitoring the area via the Internet. Any station, radio, or object that has an attached GPS is automatically tracked. APRS has been developed since the late 1980s by Bob Bruninga, callsign WB4APR, currently a senior research engineer at the United States Naval Academy.
