Info about satelite

Satellite communication system and there is no information about satellites in the system. Generally speaking, this software is weak. And not developed. Pity. Goods sold, development stopped.

    Yes there is nothing on any model to indicate iridium satellite strength or reception unfortunately. That would definitely be a good feature. Even just a bar graph like a cell phone would suffice. On the Gpsmap units you get a satellite page that shows signal strength for navigational satellites only.

    Iridium communication is not like GPS reception. With GPS, the unit listens to the GPS satellites more or less continuously. So it can display bars or approximate position error or whatever. It also knows what satellites are overhead at any given time. So it can display the constellation. (Not all iR devices have a screen for this. And some devices conserve battery by NOT listening continuously. But you get the idea.)

    Iridium is different. The unit does not attempt any communication with the Iridium network unless it needs to do so. For example, to send a message, send a track point, or perform an active mail check. Any such operation either succeeds (good sky view) or temporarily fails (bad sky view). If it fails, the device retries more or less continuously until it succeeds. For messages, there is an audible and visual indication when the send succeeds. For ANY operation, there is a status line indicator for “Iridium modem on”. Some devices have a variation of this icon which means “trouble sending.” The device has no idea of the Iridium constellation and does not need one. (Typically, there are 3 or maybe 4 satellites in view. Only one is needed.) So no screen for this.

    Bottom line: Not possible to provide signal strength indicators or constellation info. You need to be somewhat proactive about checking for success of Iridium operations.

    For the 66i/67i (and some non iR devices) there is a third party app in the Garmin IQ store called iridium where, which can (only) show you the position of the available iR satellites for your area. 

    And there are apps for a phone in the Apple/Google stores. Normally there should almost always an iR satellite be available, but the iR receiption strength depends on the given conditions (clear view to the sky, covered by trees…).

    Iphone:

    Of course it would be a good information to have basically available on all iR devices.And I would also find it very useful/helpful if the iR devices would display the iR signal strength, so the user get a hint to move for a better reception.

    Perhaps a solution like Apple is offering for the Globalstar (SOS) satellite receiption would be help/useful?

    Very informative guys thank you. I checked out that iridium where app and installed it, but just like the reviews say, it crashes every time on the 67i units.

    No it doesn’t it only has navigational satellite info, a satellite display page for it, a satellite status bar for the same, Bluetooth indicator, wifi indicator, antenna indicator for accessories. Nothing for iridium satellite information.

    you have to simply take it, as any indication of 'signal strenghth' of the iridium would be a fake anyway. There is no signal to monitor. 

    Sat listen to your call on a calling channel and will then answer on the apropriate channel within the relevant spotbeam to you.

    The sats are maximum abt 9.5min in view, so the next one is comming sure.
