Since 00.02.05 firmware version device supports Iridium devices (TSM232 įrašyt) which can send ''short burst data'' (SBD) to the server. This means that some data can be sent from the FM device to the server through satellites. From firmware version - '''01.02.22.Rev.02''', {{{device|}}} support for '''Iridium Edge''' is added. Iridium Edge features an all-in-one SBD module and antenna, with power supply. The plug-and-play satellite IoT terminal can be easily paired with {{{device|}}} device in order to expand their functionality to no GSM coverage zones.

Current Iridium implementation offers ability to generate and send SBD records after set period after the GSM signal is lost. This ensures constant connectivity as Iridium network is available globally.

===Connecting Iridium device to {{{device|}}}===

===Connecting Iridium device to {{{device|}}}===

In order to properly connect Iridium device to {{{device|}}}, Iridium has to be connect to the device via RS-232 - COM1 or COM2 (paminėt kur TX/RX jungt ir pridėt screenshot COM pinų). Additionally '''Pin No. 6''' - power control (reference in image below) must to be connected to one of the {{{device|}}} DOUTs (1/2/3/4), in order to allow device to power ON/OFF Iridium device on demand.

'''''Save/Send period''''' configures how long will FMB device wait after losing the signal to generate SBD packet. If the signal is not recovered, it will send it indefinitely (or till the SBD Upload limit is reached, if such is set).

'''''SBD Upload Limit''''' is configurable and resets every month. This option can ensure that no additional data is used so that no unexpected costs are experienced by the customer. Default value is 8000 (for 8KB plan). This option can be disabled by setting Upload limit to 0. Monthly data usage counter can be reset by using SMS/GPRS command - '''sbdlimitsreset'''.

In scenario shown in above picture when panic record is made (generated by ''Digital Input 1'' or ''Digital Input 2'') internal 90 seconds timer will start to tick and if in that timeout device will not send record through GPRS network it will be sent with Iridium satellites.

===SDB record structure===

===SDB record structure===

SDB Record which will be sent through Iridium satellites network will be different than the regular record. It will contain: 4 bytes timestamp, 3 bytes longitude, 3 bytes latitude, 1 byte record generation info, 1 byte DIN,DOUT info, 1 byte Speed value.

'''''Longitude''''' - In this packet is encoded in 3 bytes data. Server which gets this data should divide result from 46603,375 and subtract 180 in order to get actual longitude value. This coefficient is got in following way: 16777215(maximum 3 bytes value) divided from 360 (maximum longitude value then 180 is added). This calculation is used to fit negative and positive values to 3 bytes width variable.

'''''Latitude''''' - Is calculated in same way as longitude but since latitude maximum value is two times smaller than longitude it can produce a bit more accurate data. Coefficient for latitude is 93206,75. This coefficient is got in following way: 16777215(maximum 3 bytes value) divided from 180 (maximum latitude value then 90 is added). This calculation is used to fit negative and positive values to 3 bytes width variable.
