Brief description:
- Designed for MSK modulation of correction information in the RTCM SC-104 v2.2 format
- Support interface with reference station receiver according to the MNEA-0183 standard
- Automatic generation of RTCM type 6 messages if the link to the reference station is down
- The MSK modulator has two adjustable outputs
- The MSK-2ВК modulator has one adjustable output MSK
Functions:
- The Modulator is a professional radio navigational aid
- It provides MSK modulation of correction information received from the Reference Station in RTCM SC-104 v2.2 format
- Meets all the requirements of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) for frequency range 283.5 – 325.0 kHz
- Operates in hardware or software settings mode
- Provides updates of flash memory firmware via interface RS-232 (FW 2.00 and higher)
- Special circuit design provides superior stability of carrier frequency and a low level of phase noise
