SINCGARS FH (1)
Characteristics & Definitions
• Operates in the VHF-Low band from 30 to 87.975 MHz
• 25 kHz channel spacing
• 2320 possible frequencies
• Hopping rate of over 100 frequencies per second
• VINSON or KYV-5 COMSECv
•SINCGARS is an acronym for Single Channel Ground and Airborne Radio
System
• SINCGARS Frequency Hopping (FH) provides Electronic Counter-Counter
Measures (ECCM) qualities of anti-jam and Limited Probability of Intercept (LPI).
An ECM or Electronic Counter Measure is jamming. The SINCGARS radio
counters jamming by continually changing frequencies over 100 times per
second over a 57 mHz bandwidth. The hopping also leads to the fact that the
enemy cannot intercept the radios transmissions because it is not on one
frequency long enough to be detected.
• With a channel spacing of 25 kHz there are 2320 possible frequencies between
30 to 87.975 MHz. The average SINCGARS Hopset contains around 1200
frequencies. The radio hops on these frequencies in a random pattern
determined by a Transmission Security Key (TSK). This is why time is very
important. If a radios’ time is too far off from other radios, it will not be able to
communicate with them.
• Supports secure voice and data using VINSON KY-57 compatible encryption.
KYV-5 is used for enhanced data rates.
