Clock Steering Control

Clock Steering is a method that the NetRS can use to adjust its internal clock into close alignment with GPS time. Without Clock Steering, the small frequency error in the NetRS time source will cause the internal clock to slowly drift with respect to GPS time. The offset is never allowed to become greater than 500 microseconds, but to accomplish this, one millisecond adjustments must be made periodically to the internal clock. When Clock Steering is enabled, the NetRS continuously compensates for clock drift, keeping the clock offset very close to zero at all times. This eliminates the millisecond clock jumps.

It is important to note that accurate time, position and GPS measurements can be determined using either method. Both methods are compatible and equally accurate. The use of clock steering may help to reduce problems with some third party post-processing packages that do not properly account for time.
