This page links to all live downlinks from all the APRS satellites being captured by volunteer ground stations around the world as part of the APRS-Internet System (APRS-IS). These packets are captured by Steve, K4HG's FINDU.COM system.

SatGate Statistics: KE6BLR sorted all of the ground station data by the number of packets heard during July. We hope to fill in the table to help understand the difreence between omni-no-track stations and full track stations.

Your Next Pass: KE6BLR has also written a pass predictor for the next APRS satellites for your location! This data shows that with the 6 active APRS satellites on orbit, generally half the time, you are no more than 30 minutes from the next pass, 75% of the time you are less than 60 minutes to the next pass and 93% of the time your next pass is within 90 minutes as shown at right.
