What is the Search Mode?
To recover an Offshore Nomad operating in the ocean is an equilibrium between the frequency at which you would like to know the position (as high as feasible) and the cost you want to have for the Iridium communications (as low as feasible). The Search Mode is designed to reach that equilibrium. It allows a progressive increase of the position and transmission frequency as the vessel approach the buoy to be recovered. For instance, an Offshore Nomad operating at a sampling and transmission rate of one hour is difficult to recover. Through the Search Mode you may increase progressively the frequency to 30, 20, 10,… minutes as the vessel is at 15, 10, 5,… miles from the buoy.
We strongly recommend no to configure the Offshore Nomad with a long period of high sampling and transmission frequency. The cost in Iridium communications is high.
