Iridium 9555 and I do not think it has a feature for GPS coordinates. I used GlobalStar years ago but switched to Iridium when GlobalStar was having service issues. Now that their second generation constellation is active I may have a look at them when i'm ready for my next sat phone. I believe the Iridium 9575 has a GPS tracking feature which looks interesting.
