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. ASTARS: an APRS Satellite Tracking and Reporting System

APRS-IS APRS-IS APRS-IS (Automatic Packet Reporting System-Internet Service) is the common name given to the Internet-based network which inter-connects various APRS radio networks throughout the world (and space). APRS-IS is maintained and operated by volunteer Amateur Radio operators to provide world-wide capabilities to the Amateur Radio APRS RF networks and to promote the Amateur Radio service as a whole. Because the primary function of APRS-IS is to support Amateur Radio APRS on RF, the following must be kept in mind by users and software authors who inject packets directly into APRS-IS: It MUST be assumed that every packet on APRS-IS will be gated to or was gated from RF.
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. Automatic Packet Reporting System
APRS: Automatic Packet Reporting System APRS: Automatic Packet Reporting System APRS is now in its 21st year! APRS is digital communications information channel for Ham radio. As a single national channel (see map at right), it gives the mobile ham a place to monitor for 10 to 30 minutes in any area, at any time to capture what is happening in ham radio in the surrounding area.
