Motorola Defy Satellite link two-way Satellite Messenger - Our most FAQ’s

The Motorola Defy Satellite Link device is a great device for when you are out in the outdoors and have no WIFI or mobile phone reception and for peace of mind want to keep in touch with Family & Friends and the backup of an SOS button for emergencies.

Please find some of our most frequently asked questions below from customer who either have the device or are looking to purchase the device.

1. My device it is not logging onto satellites?

 - For the device to lock onto Satellites you must have an active account & plan.

- Ensure you have clear view of the sky with no overhead obstructions, if you are in North America or Europe to achieve the best signal hold the device in a southerly direction, if you are in South America, Africa, Australia, or New Zealand (South of the Equator), you should hold the device in a Northerly direction.

N.B When you open up the paired Bullitt Messenger App and touch on the Satellite icon top right of the app, the screen does display best direction for the Geo Stationary Satellites for you to turn to FIG (1).

 - On the Bullitt messenger app if you touch on the satellite icon in the top right, a screen will open up showing you the connection status, the screen also displays the Satellite direction to hold your unit in and you will see a Signal Strength SINR number - this number needs to be -3 or stronger i.e. -2, -1, 0, 1, 2….etc. FIG (2).

Important If you have had the device in an area with no signal i.e. you may have entered a building with the device still turned on, we recommend that when you come out of the building etc that you turn your device off and then with a clear view of the sky turn the device back on, this will help with the speed of Satellite lock.

This is because when the device goes into a building with no view of the sky, to save battery gradually the device will have periods where it stops looking for satellites and these periods will keep becoming longer, when back outside turning the unit on and off will start the process of looking for satellites again from the start, for a quicker satellite lock.

The indicator at the top right of the app displays your bluetooth status, battery indication & satellite lock FIG (3).

5. Why are my text messages typed on the app are not being sent?


When sending a message via the Bullitt messenger app, if you do have a mobile phone signal the Bullitt messenger app will try to send your messages this way to keep your Satellite messages allowance down, but if you are in an area with a weak mobile signal, you can then have an issue with your messages not being sent.

When you have a Satellite lock there is now an option in the app when sending your messages, to select to only use Satellites, we recommend when in an area that is dropping in and out of mobile signal that you select the option to use Satellites FIG (4).

6. What satellite system does Motorola Defy Satellite Link use?

The Motorola Defy Satellite Link uses the Inmarsat and Echostar geostationary satellite networks. These groups of satellites revolve around the equator at an altitude of around 35,000km.

Using GEO satellites enables the Motoroal Defy Satellite Link to provide stable international coverage. A user does not have to change their existing behaviour, you are generally stationary when you send a message,

GEO connected devices also provide faster access, latency is ~10 seconds compared to ~15-120 seconds for LEO services.

The device can connect to a number of geo-satellite constellations including Inmarsat, Echostar and others.

It takes approx. 500 milli seconds to bounce a message to the satellites and back to the ground station. Any message is then translated into the IP network ensuring that overall latency is ~10 seconds compared to ~15-120 seconds for LEO services

GEO satellites are positioned above the equator and effectively orbiting the earth at the same speed as the earth rotates. Effectively they appear to be stationary in the sky, easier to locate and communicate with.

7. Positioning of the GEO Stationary Satellites in the sky?

To optimise your satellite connection, it is recommended that you place your satellite link in the general direction of the satellite. Typically, in the northern hemisphere this will be in a southerly direction. In the southern hemisphere, you should try to face northerly.

The Bullitt messenger app does display the best direction for you to hold your device in as per FAQ (1) above.



8. Does the person receiving a message need to use the app?

If the person receiving your message does not have the free to use Bullitt Messenger app they can read the message, but if they want to reply to it or wish to see your location, they will need to download the app.

9. What happens if you press SOS and are unable to use your phone?

A SOS will still be sent with your location to Focuspoint International. They will look at your location/any medical history entered in the SOS settings, if you enter these details, it gives the monitoring centre a better ability to work out the appropriate level of response to send to you. In the instance that you cannot communicate they will send who they deem the most suitable given your location and any medical history they have available through the application.

10. When you send & receive messages via the Defy Bullitt Satellite Messenger App (if you have a mobile signal do they come of your Satellite Message allowance?
