1. RTK update rate means the position update rate of the rover working in the “extrapolation” mode. In the

extrapolation mode you may use the base with measurements update rate = 1 Hz and run the rover at
100 Hz RTK update rate.

2. In-Band interference usually is caused by harmonics of external transmitters (like TV stations) located

close to GPS receiver. Interference decreases SNR and may stop receiver operation completely. Our In-
Band Interference Rejection technique suppresses interference and recovers SNR. Multipath signal
propagation worsens code/phase measurements. Advanced Multipath Reduction technique reduces this
harmful effect.

3. The accuracy estimate is applicable to base lines up to several hundreds of km. But normally RTK

works predictable on base lines up to 50 km.
