When balloons we are tracking are at low attitude on launch and descent the closest iGates can be 100km or more away and we dont get updated from the onboard trackers. To help get accurate positions we have installed APRS iGate software on our laptop and connected to our Kenwood TH-D72A. APRSISCE is developed by Lynn Deffenbaugh, KJ4ERJ, its very impressive software .. many thanks Lynn.

IF our radio can hear and decode the APRS packet while its connected to the iGate laptop and the laptop has internet access via our iphone hotspot, the packet will be gated to the aprs servers and visible on aprs.fi and spacenear.us
