What is the running cost of the Avidyne product, Fuji?
Iridium charge an eye watering ~ £2/minute for 2400 bits/sec data.
Avidyne probably did an OEM deal with Iridium but the cost of downloading a ~100kbyte radar image is worth examining.
How much is XM? I heard about $30/month. Sat data has the potential to blow away that much on one flight if you go OTT, and that is on Thuraya which is ~ 10% of the cost per byte of Iridium.
