I'm involved in a project
that uses Iridium
for communication, and I have some questions regarding its services:
1# How long does it takes to acquire a stable signal suitable for data transmission
2# Above the 40 Km of altitude will I be able to receive the signal properly? AFAIK Iridium
satellites orbit at 35Km of altitude and use directional antennas pointed to the ground land.
3# Iridium claim its data transmission
is 2.4 Kbps, does this really match with the real data transmission rates?
4# Is it worthless to compress the email
before sending it? Or its not necessary because Iridium compress data by itself.
5# How long should I take in order to send a 72 KB email
Thank you in advance!
