Those in charge of an operation need to know where people are. TETRA radios from Airbus Defence and Space make it easier because they all contain a positioning module.
The radios can be tracked. For example:
'Where are you' lets the radio user take advantage of the location information on the radios.
In short, 'Where are you' becomes the question no-one needs to ask. The user can easily send a 'Where Are You question' to a colleague or team. They can answer by pressing the push-to-talk key.
The user’s radio will now display an arrow that points to the colleague’s direction. He can also see how far the colleague is in that direction.
'Where are you' is only available in TETRA radios from Airbus Defence and Space.
The TH1n light-weight radio, TH9 handportable TETRA radio and the THR9 Ex ATEX TETRA radio are now even faster and easier to locate. They contain the GNSS (Global Navigation Satellite System) positioning module. Also Tactilon Dabat, a smartphone and a TETRA radio in one device includes the GNSS module.
The GNSS module can use any two of these satellite systems at once:
Tall buildings can block a radio’s view to a satellite, and such an area is called an urban canyon. But where the radio may not get line-of-sight to one satellite, another may be in view. The GNSS can use two satellite systems and get more accurate positioning – even in urban canyons.
Use the TETRA radios to track
The radio can send its coordinates as an SDS message
