- Page 2 Iridium Push-To-Talk Key Points An Iridium satellite radio is a critical communication tool for a variety of scenarios. While standard mobile phones require very little preparation and training, satellite-enabled devices may be unfamiliar to users at first. It is important to ensure your team is familiar with the recommendations of how to best use two-way satellite radio communications.

Contact GlobalSat if you have an questions regarding the operation & setup of your Iridium satellite PTT device. +61 7 3282 8504 | sales@globalsat.com.au...
- Page 4 Icom IC-SAT100 Best Practice Guide STEP 1: UNDERSTANDING THE IRIDIUM NETWORK There are 66 Iridium satellites orbiting the globe at a speed of 30,000 kilometers per hour & at a distance of around 780 km above the earth. They travel latitudinally moving South to North, maintaining their spacing &...

Page 5: Understanding Talk Groups
Talk Groups can be manipulated over the air in real time via the Iridium PTT Command Center which is set up and managed by GlobalSat. Marked 1-15 on the radio, Talk Group names are displayed on the screen when the group is selected. The “Priority” Talk Group will interrupt transmission on all other Talk Groups. - Page 6 STEP 3: SITE SURVEY & SURROUNDINGS With some basic understanding of the Iridium LEO satellite network in mind, it’s important to remain conscious of your surroundings when you’re using any kind of satellite equipment. Anything that obstructs the antennas view to the sky, will reduce the signal strength and therefore reduce the performance of your device.

Page 7: Basic Operation
STEP 4: BASIC OPERATION Before you begin, you need to ensure that you are outside with clear view to the sky. If the transceiver is turned on inside, it can enter a searching loop and can fail to connect when you go outside. - Page 8 STEP 5: TRANSMITTING (TALKING) As the Iridium PTT devices are sending voice messages via satellite, it’s important to follow these guidelines to ensure messages are transmitted and received to all parties LOUD & CLEAR. CAUTION: DO NOT Transmit without the antenna connected STEP 1 •...
- Page 9 CORRECT BEHAVIOR (Talking) • HANDHELD - Hold the device in front of your face with the antenna facing the sky • CHEST HARNESS - Keep the device positioned high on your right shoulder so the antenna is not obstructed by your body.
- Page 10 STEP 6: RECEIVING (LISTENING) When you’re not speaking directly or involved in a conversation, generally you’ll be carrying on with the task at hand however it’s very important that you remain conscious of potential obstructions in order to maintain optimum signal strength. Keeping the device in the correct position will ensure you are contactable at any time.
- Page 11 CORRECT BEHAVIOR (Listening) • When a call is received, STOP, STAND STILL and LISTEN • HANDHELD - Hold the device up with the antenna facing the sky • CHEST HARNESS - Keep the device positioned high on your right shoulder so the antenna is not obstructed by your body.
- Page 12 STEP 7: PTT BUTTON (notes) Correct use of the PTT button is crucial so take note of the key points below: • Press & hold the PTT button for the complete duration of spoken transmission & only release the button when you have finished speaking.

Page 13: Receiving An Emergency Call
STEP 8: EMERGENCY KEY The IC-SAT100 satellite radio has an orange emergency key located on the top of the transceiver. Holding this key for 2 seconds will transmit an emergency call over the PTT network to all users, interrupting transmission regardless of their current talk group/channel (when set as “Priority”... - Page 14 RECOMMENDATIONS: CHEST HARNESS When using the IC-SAT100 satellite radio as a handheld, it’s important to keep the device in a consistent and correct position to maintain satellite signal and connectivity to the Iridium network. Using a chest harness to hold the radio has several benefits and will ensure optimum performance of the device when on foot.

Page 15: Speaker Microphone
RECOMMENDATIONS: SPEAKER MICROPHONE If you’re using a chest harness or an in-vehicle cradle system for the satellite radio, a hand held external speaker microphone lets the radio remain in a fixed position while you’re TALKING or LISTENING. This not only helps with maintaining satellite signal but... -
Page 16: External Antenna
RECOMMENDATIONS: EXTERNAL ANTENNA Connecting a high gain external antenna to your satellite radio will improve performance and allow you to use the device whilst traveling in a vehicle or working in a building. You can connect an external antenna directly to the top of the radio however this is not recommended for frequent use due to the small and vulnerable SMA connector that can be easily damaged. -
Page 17: Text Messaging
RECOMMENDATIONS: TEXT MESSAGING You can send and receive short text messages (up to 100 characters) via the Iridium PTT network. This is a standard feature on all IC-SAT100/M devices and comes at no additional cost. There are two (2) ways to send and receive messages: Directly on your IC-SAT100/M device •... -
