What are the frequency channels that GLONASS use as a technical channel?
a) i=-7 and +4
b) i=+5 and +6
c) i=-7 and +12
d) i=-2 and +7

Explanation: The GLONASS use i= +5 and +6 frequency channels as a technical channel. They are only used for a limited periods of time during orbital intersections or other periods of exceptional circumstances.
