The JQE-103 is a float-free compact type EPRIB designed to transmit the 406MHz emergency signal and the 121.5MHz homing signal in accordance with IMO/CCIR and COSPAS/SARSAT regulations. This equipment must be fitted to comply with IMO SOLAS regulations.
The 406MHz satellite EPIRB, thrown into the sea from a vessel or automatically released from the bracket in distress, automatically emits a 406Mhz emergency signal, which the COSPAS/SARSAT satellite receives and relays to a Local User's Terminal(LUT) on 1.5GHz. The LUT decodes the signal information including the location of the EPIRB and transmits it to a Rescue Co-ordination Center(RCC) for quick start of SAR operations by aircraft and vessels.
The emergency transmission on 406MHz includes a digitally encoded message containing the ship's identity and nationality, thereby enabling an RCC to quickly catch the distress information.
The ship's location can be determined with an accuracy of 2 to 5km.
The JQE-103 incorporates a 121.5MHz emergency transmitter to emit a homing signal to the search and rescue aircraft in the immediate vicinity of the ship in distress.
The JQE-103 is automatically released from the float-free release bracket under water pressure at a depth of less than 4 meters to float to the surface for continuous emissions for 48 hours or more with automatic flashing of the strobe light.
