"TGM100 update: System has been flown on a Logo helicopter as well as several Tarot 680 drones.  Even without external correction, it performs great, much better than the M8N receiver. However, the RTK mode is not solid so more work…"

"The LED feature is a quick and easy indication of how many satellites the system has locked on to.  The "ON" time is proportional to the SNR (<35dB is a solid ON).  The LED feature certainly does not improve signal reception,…"

"For testing, maybe it's useful, but I prefer to check both SNR and SkyPlot. As an antenna on Drone, I don't think it helps, but increases the weight."

"Chris, the LED feature is 80% cool and 20% useful (depending on who you ask :) ).  It only adds a few dollars to the overall cost and it provides instant information about the number and "spread" of the received satellites. …"
