4) operation with exterior unit – GPS;
5) operation with exterior terminal (personal computer) through RS232 interface;
In analog mode radio station Р-173М provides the following functions:
speech transmission/reception with frequency modulation and data with frequency-shift keying.
In digital mode radio station Р-173М provides the following functions:
1) file transmission/reception at rate up to 10 МByte (with receipt acknowledgement) in a mode without voice priority:
a) at operating frequency at the rate of 12,8 кBit/s;
b) at a pre-selected frequency (auxiliary channel) with further return to the operating frequency at the rate of 12,8 кBit/s;
2) file transmission/reception at rate up to 10 МByte (with receipt acknowledgement) in a mode with voice priority (C4I) at the operating frequency at the rate of 10 kBit/s;
3) transmission/reception of address short message with acknowledgement of receipt;
4) transmission of short messages in circular mode with acknowledgement of receipt;
5) operation with exterior unit GPS enabling performance of the following functions:
а) determination of object’s own coordinates;
b) request of coordinates of remote object under individual number;
c) request of coordinates of remote objects (up to 15 units) in circular inquiry mode;
d) periodic transmission of own coordinates.
6) determination of radio station parameters from PC.
Radio station is powered by voltage of 27 V from DC mains.
Radio station can be completed with additional power supply units:
- to be powered from 12 V direct-current mains;
- to be powered from 220 V alternating-current mains.
The Radio Station remains serviceable under the environment temperature from minus 40°С to plus 50°С.
