Inmarsat Vs Iridium

In Australia, Iridium and Inmarsat are two dominant networks. We have read ‘independent’ reports commissioned by various parties that show the overall advantage being held by one phone / network over the other, however in our view here are some important questions to ask when selecting your phone and network.

 

1. Do I want to be available to receive calls on the phone most of the time?

2. Do I want to use it in the car or boat?

3. Will I be using the phone in very hilly terrain?

4. Is the phone primarily for emergency / convenience purposes when I am travelling out
    of normal mobile range?

5. How often am I likely to be in a circumstance when I may need to use the phone?

 

The following is provided and intended as an introductory guide only, to assist with satellite phone selection preferences and is not intended as an exact comparison, nor are the comments absolute. We invite you to discuss your particular needs, budget and usage pattern with us.
We can then recommend the best value connection for your requirements and usage pattern.

*LEO- Low Earth Orbit.
These rotate around the earth so in mountainous terrain you are more likely to receive coverage at some time whereas if you are in a valley with a phone that uses a geo-synchronous satellite and your path to the satellite is blocked by the mountain then you will need away from that obstruction until you have clear line of sight to the satellite. LEO is similar to a giant mobile phone network in the sky but instead of you driving through the network, the network revolves around you (the Earth).

*Geo-synchronous.
These satellites are always in the same position relative to the earth. These may have a lower call dropout rate as in normal use you are not handed from one satellite to another.
See angle look up chart below.

**Iridium 9505A
The Iridium 9505A has been very popular in aircraft with many operators choosing to install hands free kits with external antennas etc. The 9555 and 9575 do not fit into these kits. As at November 2011 these phones are still available to us. Please call to confirm availability.

 

*** Iridium Pre-paid cards

The validity period or life of the card depends on the amount of pre-paid airtime purchased. Basically the more airtime you purchase the longer you have to use it. Iridium have excellent pre-paid options including where users require access over a short term 1-3 months and moderate to higher usage 1- 2 minutes / day and above. Card validity periods vary from one month to two years with extension periods usually available as long as top ups are purchased and activated prior to relevant card expiry dates. Please contact us for information regarding your requirements.

 
Inmarsat view angle map 
Looking at the map, you can approximate the direction and how many degrees up from the horizon one of the Inmarsat satellites will be (where to point your phone with the antenna fully extended) e.g. If you are at Alice Springs you will point the Inmarsat IsatPhone Pro in a northerly direction at about 60 degrees above the horizon. If you are in Darwin you would point the phone in a northerly direction but almost straight up at at 75 degrees (not quite verticle at 90 degrees). The phone will need a clear line of sight to that position in the sky i.e. clear of buildings, mountains, tree foliage etc
