Confidential document and information
The MP50 is available in two versions, MP50 with Li-Ion battery and MP50M with NiMh
battery.
Through the internal microphone in the MP50, it is possible to communicate with the
survivor/ground rescue party without helmet removal.
Depending on the configuration and part number, the MP50 is equipped with a GPS receiver.
The position of the MP50 may be polled by the PNG Base Station, and presented on the
PNG Control Panel in the aircraft. In addition the Base Station can be connected to a moving
map system and send handheld position data at regular intervals.
The PNG Base Station is typically connected to the aircraft ICS, and may support multiple
connection points for audio. The base station is capable of delivering a PTT signal to other
systems, as well as triggering transmission based on a received PTT signal or VOX
activation.
Radio
The PNG system operates a wireless link between the base station and the MP50 in the
UHF band. Exact frequency configuration is done at production, based on customer input to
available frequencies and bandwidth in the region they are to be operated in. The PNG
system will normally be configured within a 10 MHz band in the frequency range 397 to 470
MHz. The base station will support the full 397 to 470 MHz range (depending on the antenna
installation in the aircraft), while the MP50 supports 10 MHz bands through the 397 to 470
MHz band, depending on the installed antenna. Antennas are available through the band.
The wireless link is a single frequency, duplex, interception free, digital radio link.
The MP50 operates at an output power of up to 400mW using a licence specific frequency
allocation.
The PNG system will not set any limit to the number of simultaneous receivers, but the
number of simultaneous transmitters is limited by the available bandwidth and allocated
timeslots. The PNG system allows three simultaneous transmitting handhelds.
The MP50 supports Maritime VHF mode, and channels can be configured in the 156-162
MHz band.
