APRS is in Orbit APRS space frequency is 145.825 MHz Also via GO-32 on 435.225 downlink, 145.85 MHz up Feb 2009, K9DCI

Into Space..PCSAT The Prototype Communications Satellite, is a US Naval Academy Aerospace student project. ANDE and RAFT in Dec 2006 APRS space frequency is published as 145.825 As of June 2008 currently useable: ISS, GO-32, ECHO and PCSAT when it is in good sun.

PCSAT Satellite Launched Sept 2001 from Kodiak Alaska The first APRS satellite, and has since been joined by 5 other such satellites Can capture Emergency /Priority messages from THD7 / D700 radios anywhere on the globe and retransmit these signals on the USA VHF 144.39 APRS frequency. See live downlink on http://pcsat.aprs.org

International Space Station ARISS supports APRS on its 145.80/145.99 packet system. Use digipeater path VIA ARISS. PCSAT2 was also on ISS 2005-2006 Also has FM voice repeater capability PCSAT2, was the second APRS digipeater satellite. See live downlink on www.ariss.net

Now GO-32 TECHSAT-1b GO-32 now supports APRS on its 435.225/145.85 packet system. APRS up on 145.85 (PC’s and messages) Mic-E up on 145.93 (D7 and D700’s) 9600 Baud! See live downlink on www.ariss.net

ASatLogger APRS Satellite Tracker Feb 2009, K9DCI Current Ver 0.6.1 Beta 0.6.2 Feb 2009, K9DCI

ASatLogger Features Facilitate comms with APRS and Packet Satellites. Control Kenwood D7, D700, D710's - serial port. Adjust D7 and D700 radio's automatically for Doppler shift - not the D710. ASatLogger reconfigures D7/D700/D710 in seconds for different satellite. Relay satellite packets to the APRS-Internet System and FindU.com. Log Packets to disk for a permanent record. Allow others to monitor Satellite communications via your station. Control a D7, D700, D710 and operate AsatLogger via Internet. Files for common satellites and radios included. Track multiple satellites - requires a Nova DDE Server and D7, D700, D710.
